I’ve been giving lectures on Peak Oil for over a decade now, and always look forward to the question period after the main show. It’s an opportunity to interact with the audience, and to see where my presentation may need tweaking or where my thinking may be shallow or incorrect.
Now Post Carbon Institute is offering a tool to help others who wish to give presentations about our global sustainability crisis—a beautiful PowerPoint called “YOU ARE HERE: The Oil Journey,” featuring a script and images that are geared to a general audience with little prior understanding of the issue. Presenters of “YOU ARE HERE” are likely to be bombarded by a lot of the same questions I’ve heard over the years, so I thought it might be helpful if I compiled some of those.
Here are the top 11, along with brief sample replies and some resources for further reading.
1. But what about natural gas? I’ve heard we had a 100 year supply. Can’t we use natural gas in place of oil? Won’t natural gas be a good “bridge fuel” to get us to a green, growing energy economy?
A: Actually, U.S. proven reserves of natural gas amount to only about 12 years’ worth of supply. More gas resources will no doubt be discovered, thus adding to those reserves, but most of the new sources will be in “tight” shale deposits, where production costs and depletion rates are high. Currently there is a shale gas supply glut due to very high rates of drilling a few years ago, when natural gas prices were several times their current level. But now that gas is so cheap, the producers that specialize in shale “fracking” are actually losing money; therefore they’re cutting back on drilling. In a year or two we will see declining production and higher prices. Bottom line—while it’s true that new technology has increased natural gas supplies over the short term, the long-term outlook is more complicated. Natural gas is a depleting fossil fuel, and technology cannot change that fundamental fact. Natural gas will not substitute in any meaningful way for increasingly expensive oil, because very few vehicles currently are able to use natural gas and it will take decades to change that situation—and gas supplies won’t be sufficient even if we could retrofit existing vehicles fast enough. Moreover, the climate impact of producing and burning gas from shale deposits is no better than that of mining and burning coal—so the environmental argument for using more natural gas doesn’t hold up to scrutiny.

2. I’ve read about the extraordinary potential for “tight oil”—petroleum trapped in low-porosity rocks like shale, that’s produced by hydrofracturing and horizontal drilling. Apparently so much of this is coming from North Dakota now that it’s causing total U.S. oil production to increase. Some people are even saying that America could be oil independent within a few years.
A: Yes, tight oil production in North Dakota is booming—but why? Geologists have known about the Bakken oil deposits for a long time, and have had the technology to get the oil out of the ground. But costs of extraction were too high to justify drilling. Now that rates of global crude oil production are stagnant, oil prices are very high—and that makes production of marginal sources like tight oil economically viable. And that in turn means continued production from these sources depends upon continued high oil prices: if the price level falls, production will slow. Several analysts have described recent claims for reserves and potential production rates from tight oil plays as overoptimistic. A realistic forecast shows U.S. crude oil production continuing to increase for the next decade (as a result of additional tight oil and deepwater production), but then resuming its decline. In this most-likely-case scenario, U.S. crude oil production in 2020 will not come close to matching the peak it achieved in 1970. Unless Americans reduce their oil consumption significantly, the nation will still be hooked on imports.
3. What about coal? I heard we have a 250-year supply. Won’t coal keep our economy growing, even if the environmental consequences are awful?
A: Several recent studies (including ones by the U.S. Geological Survey) have concluded that coal supplies for the U.S. and the world as a whole have been exaggerated. Enormous amounts of coal exist, but the great majority of it is unlikely ever to be mined because of its depth, the insufficient thickness of seams, and the quality of the resource. As with other fossil fuels, we have already picked the low-hanging fruit. Two recent studies conclude that global coal output could peak within the next decade or so. Meanwhile, as China’s consumption grows (that country now uses 4 billion tons per year, fully half the world’s production), coal prices are set to increase substantially even in countries that are self-sufficient in supply, like the U.S.

4. Then what about nuclear? Couldn’t modular/thorium/breeder reactors power the world for centuries?
A: Too expensive and too risky. A detailed report in a recent issue of The Economist magazine—not known for an anti-nuclear stance—called nuclear power “the dream that failed,” and concluded that its role in the foreseeable world energy picture will never be more than marginal. The ongoing nuclear catastrophe in Japan has led that country to abandon nuclear power, and Germany is following suit. Even though China appears to be doubling down on its nuclear bets, from a global perspective the industry is essentially moribund.

5. Isn’t the real problem human population? What’s a truly sustainable human population? Won’t there be a huge die-off?
A: Yes, population is a vitally important issue. Population growth exacerbates every problem facing us. As the global economy stagnates or contracts, declines in per-capita output can be reduced by policies to rein in population growth. Moreover, a good argument can be made that family planning investments will benefit the poorest nations first and foremost, since large, poor families tend to spend all their income on food and shelter, leaving no surplus for education or the formation of a small business. But while good population policy is desperately needed, it is no cure-all: changing demographic trends is a slow process, and many of the challenges facing us will converge over the course of the next couple of decades—far too quickly to be adequately addressed by reducing birth rates. So we need to think systemically to address a range of economic and ecological issues simultaneously while doing our best to support seven billion humans and counting.

6. When I think about all of these challenges, I just get overwhelmed. Where do we go for hope?
A: First, address your mental state. If you’re emotionally overwhelmed by information about climate change and resource depletion, you may need to ration your news intake so as to increase your effectiveness at helping tackle these enormous global problems. Spending hours a day in front of a computer screen feeds depression. Take time off, go outdoors, do some gardening, and interact with other people face-to-face. You will probably find inspiration in community resilience-building projects, where you can see and touch the results of your and your friends’ efforts. Cultivate a creative hobby and spend time in nature. Your efforts to save the world will be far more effective if other people perceive your mental and emotional state as being grounded and balanced. That doesn’t mean you should deny and suppress the pain and fear that any healthy human inevitably feels when contemplating the fix we’re in. Allow yourself to feel those emotions (otherwise you’ll be detached and inauthentic at best, unhinged at worst), but don’t wallow.

7. I’ve been thinking this way for years. The problem is all those people who don’t “get it.” How do we convince them?
A: I wish I had a sure-fire answer to that one. Sometimes simple persistence pays off. If people have dug themselves into a certain worldview, it may take time for them to change their views. It’s important for you to have the facts at your command, but it’s just as important to create “frames,” as George Lakoff calls them—stories that make sense of the data. Often simple metaphors, such as “low-hanging fruit,” help people grasp the essential character of situations that might otherwise require lengthy explanation. It’s also important to tailor the message to the audience: if you understand where other people are coming from, it’s much easier to connect with them. Unfortunately, there are many people who are completely invested in maintaining a cornucopian view of the world, and there may be no way of reaching those people. Don’t waste your time on them; focus your attention on people who can be educated.

8. Isn’t the real problem one of distribution? If wealthy Americans didn’t consume so much, there’d be enough for everyone. Similarly, if the “one percent” weren’t siphoning all the world’s wealth, we’d all be doing fine. Shouldn’t we just be fighting for fairness?
A: As long as our economy is set up in such a way that it requires continued growth in order to function, then even if we distribute wealth fairly we will hit resource limits and fail. That’s not to say that equity is unimportant. As the national and global economy inevitably shift from growth to contraction, more equitable distribution will be necessary if we are to maintain social stability. If distribution of wealth becomes even more inequitable (and that’s the current trend), people will rightly conclude that the system is unfair and not worth saving. They will rebel, and governments will crack down brutally to maintain the status quo. The result will be a chaotic, violent collapse of the entire system. It doesn’t have to end this way. If wealth is more evenly distributed as a result of reform, and if everyone is encouraged to understand the challenge facing us, then people can be persuaded to make shared sacrifices in order to build an economy that fits within Earth’s limits.

9. Aren’t the oil and car companies sitting on patents for free energy devices or carburetors that get 100 mpg? Can’t we solve our energy problems just by defeating these evil corporations?
A: I’ve heard stories about suppressed energy technologies, but have been unable to verify them. Typically the stories entail oil or car companies buying up patents and hiding them, but every patent ever issued in the U.S. is freely searchable, so it should be easy enough to find these “suppressed” inventions. On the other hand, many machines that have been patented don’t actually work, and that’s why they haven’t been commercialized. Now, it’s true that the automobile industry actively discouraged the development of new safety features, including seat belts, and also lobbied Congress for decades to delay energy-efficiency regulations. Moreover, the oil companies have spent enormous sums in efforts to distort and mute both the scientific research and the public discussion regarding climate change. Such corporate abuses must be brought to an end, and I support activist efforts to do that. However, even if they succeed, that won’t solve the basic problem: we’ve become addicted to energy sources that are unsustainable, and there are no “silver bullet” alternatives that will enable us to maintain economic growth such as we’ve seen over the past century.

10. The problems seem so huge, the solutions so small. How can little efforts like Transition Towns hope to deal with war, resource depletion, and climate change, if national governments can’t?
A: There are two answers to that question. First: We have to do what we can. Yes, fundamental national and international reforms are needed to deal with global problems like climate change and resource depletion, and activist efforts to address those issues are needed now more than ever. But we are seeing a general deterioration in the ability of our national political system to respond both to converging global problems and to the public’s concerns. Reforming our own national government is a big, multi-decade job, if it’s even possible to accomplish. Our economic and environmental problems will not remain on hold while we put the country’s political system in order, so we have to accomplish what we can where we have more leverage—at the local level. Second: There are good reasons for working at locally anyway, regardless of difficulties in achieving national and international reforms. Localization is inevitable as transport fuels become more scarce and expensive. If we don’t increase local self-sufficiency proactively, the reversal of globalization will result in the collapse of essential support systems—so building local food systems should be our first priority. Also, local organizing creates the necessary basis for political, social, and economic change at higher levels.
11. Innovation has solved problems and opened opportunities for us in the past. Why would you think that innovation can’t solve all our problems now? Don’t we just need to put more money into research?
A: Innovation will be essential to our adaptation to our new economic reality. Some new technologies (such as renewable energy and ways to use energy and resources more efficiently) will need to expand significantly. But every technology has its costs. Economies cannot grow forever, even if they are based on renewable energy. We must adjust to the fact that our own civilization has reached limits with regard to population, water, soil, raw materials and energy. In the end, our adaptation will require as much social innovation as technological change, as we learn to live with less, and to live more equitably.

With record high unemployment, a reeling global economy, and concerns of food shortages, the world as we know it is changing. But even as these shifts expose inequities in the health and food systems, many experts hope that the current moment offers an opportunity to build a new and more sustainable food system.
1. Be My Guest: Reflections on Food, Community, and the Meaning of Generosity by Priya Basil (forthcoming November 2020)<p>Priya Basil explores the meaning of hospitality within a variety of cultural, linguistic, and sociopolitical contexts in this short read. Basil uses her cross-cultural experience to illustrate how food amplifies discourse within families and touches on the hospitality and the lack thereof that migrants and refugees experience. <em>Be My Guest </em>is at once an enjoyable read and a hopeful meditation on how food and hospitality can make a positive difference in our world.</p>
2. Biodiversity, Food and Nutrition: A New Agenda for Sustainable Food Systems by Danny Hunter, Teresa Borelli, and Eliot Gee<p>In <em>Biodiversity, Food and Nutrition</em>, leading professionals from Bioversity International examine the positive impacts of biodiversity on nutrition and sustainability.

Through this analysis, the authors propose that the localized activities in these countries are not only benefiting communities, but are transferable to other regions.</p>
3. Black Food Geographies: Race, Self-Reliance, and Food Access in Washington, D.C. by Ashanté M. Reese<p>In <em>Black Food Geographies, </em>Ashanté Reese draws on her fieldwork to highlight community agency in response to unequal food access. Focusing on a majority-Black neighborhood in Washington, DC, Reese explores issues of racism, gentrification, and urban food access. Through her analysis, she argues that racism impacts and exacerbates issues of unequal food distribution systems.</p>
4. Black Food Matters: Racial Justice in the Wake of Food Justice edited by Hanna Garth and Ashanté M. Reese (forthcoming October 2020)<p>Access, equity, justice, and privilege are the central themes in this forthcoming collection of essays. The food justice movement often ignores the voices of Black communities and white food norms shape the notions of healthy food. Named for Black Lives Matter, <em>Black Food Matters </em>highlights the history and impact of Black communities and their food cultures in the food justice movement.</p>
5. Diners Dudes & Diets: How Gender and Power Collide in Food Media and Culture by Emily J.H. Contois (forthcoming November 2020)<p>In <em>Diners, Dudes & Diets</em>, Emily Contois looks at media's influence on eating habits and gendered perceptions of food. Focusing on the concept of dude foods, the book follows the evolution of food marketing for men. In doing so, Contois shows how industries used masculine stereotypes to sell diet and weight loss products to a new demographic. She argues that this has influenced both the way consumers think about food and their own identities.</p>
6. Feeding the Crisis: Care and Abandonment in America’s Food Safety Net by Maggie Dickinson<p>The Supplemental Nutrition Assistance Program (SNAP) is essential for individuals who face food insecurity on a daily basis. Still, the program fails to reach many, including those who are unemployed, underemployed, or undocumented. <em>Feeding the Crisis</em> provides a historical overview of SNAP's expansion and traces the lives of eight families who must navigate the changing landscape of welfare policy in the United States.</p>
7. Feeding the Other: Whiteness, Privilege, and Neoliberal Stigma in Food Pantries by Rebecca T. de Souza<p>In <em>Feeding the Other</em>, Rebecca de Souza explores the relationship between food pantries and people dependent on their services. Throughout the work, de Souza underscores the structural failures that contribute to hunger and poverty, the racial dynamics within pantries, and the charged idea of a handout. She argues that while food pantries currently stigmatize clients, there is an opportunity to make them agents of food justice.</p>
8. Feeding the People: The Politics of the Potato by Rebecca Earle<p>In <em>Feeding the People,</em> Rebecca Earle tells the story of the potato and its journey from a relatively unknown crop to a staple in modern diets around the world. Earle's work highlights the importance of the potato during famines, war, and explains the politics behind consumers' embrace of this food. Interspersed throughout are also potato recipes that any reader can try.</p>
9. Food in Cuba: The Pursuit of a Decent Meal by Hanna Garth<p>In <em>Food in Cuba</em>, Dr. Hannah Garth looks at food security and food sovereignty in the context of Cuba's second largest city, Santiago de Cuba. Throughout the work, Garth defines a decent meal as one that is culturally appropriate and of high quality. And through stories about families' sociopolitical barriers to food access, Garth shows how ideas of food and moral character become intimately linked.</p>
10. Franchise: The Golden Arches in Black America by Marcia Chatelain<p>Scholar, speaker, and strategist Marcia Chatelain provides readers insight into the ways fast food restaurants expanded throughout Black communities. Dr. Chatelain traces their growth during the 20th century and their intersection with Black capitalists and the civil rights movement. This book highlights the dichotomy between fast food's negative impacts on Black communities and the potential economic and political opportunities that the businesses offered them.</p>
11. Honey And Venom: Confessions of an Urban Beekeeper by Andrew Coté<p>In <em>Honey and Venom,</em> Andrew Coté provides a history of beekeeping while taking the reader through his own trajectory in the industry. A manager of over one hundred beehives, Coté raises colonies across New York City, on the rooftops of churches, schools, and more. Coté's<em> </em>passion for beekeeping comes through clearly as he narrates the challenges and rewards of his career.</p>
12. Life on the Other Border: Farmworkers and Food Justice in Vermont by Teresa M. Mares<p>Agriculture, immigration, and Central American and Mexican farm workers may conjure ideas of the Mexico-U.S. border, but in <em>Life on the Other Border</em>, Teresa Mares gives a voice to those laboring much farther north. Mares introduces the readers to the Latinx immigrants who work in Vermont's dairy industry while they advocate for themselves and navigate life as undocumented workers. This is an inspiring read that touches on the intersection of food justice, immigration, and labor policy.</p>
13. Meals Matter: A Radical Economics Through Gastronomy by Michael Symons<p>In <em>Meals Matter</em>, Michael Symons argues that economics used to be, in its essence, about feeding the world but has since become fixated with the pursuit of money. Symons introduces readers to gastronomic liberalism and applies the ideas of philosophers like Epicurus and John Locke to the food system. Through this approach, he seeks to understand how large corporations gained control of the market and challenges readers to rethink their understanding of food economics.</p>
14. No One is Too Small to Make a Difference by Greta Thunberg<p>Greta Thunberg addressed the United Nations at the 2019 UN Climate Action Summit and has since been a global symbol of environmental activism. Her community organizing and impassioned speeches are uncompromising as she argues that climate change is an existential crisis that needs to be confronted immediately. <em>No One Is Too Small to Make a Difference </em>includes Thunberg's speeches and includes her 2019 address to the United Nations.</p>
15. Perilous Bounty: The Looming Collapse of American Farming and How We Can Prevent It by Tom Philpott (forthcoming August 2020)<p>In <em>Perilous Bounty</em>, journalist Tom Philpott critically analyzes the centralized food system in the U.S. and argues that it is headed for disaster unless it sees some much-needed changes. Philpot argues that actors within the U.S. food system are prioritizing themselves over the nation's wellbeing and provides well-researched data to back up his claims. Providing readers insight into the experiences of activists, farmers, and scientists, this is a great read for those starting to learn about the state of the country's food system and for those who are already deeply involved.</p>
16. Plucked: Chicken, Antibiotics, And How Big Business Changed The Way The World Eats by Maryn McKenna<p>In this exposé on the chicken industry, acclaimed author Maryn McKenna explains the role antibiotics played in making chicken a global commodity. <em>Plucked </em>makes it clear that food choices matter and show how consumers' desire for meat, especially chicken, has impacted human health. McKenna also offers a way forward and outlines ways that stakeholders can make food safer again.</p>
17. Stirrings: How Activist New Yorkers Ignited a Movement for Food Justice by Lana Dee Povitz<p>Between 1970 and 2000, food activists in New York City pushed to improve public school lunches, provide meals to those impacted by the AIDS epidemic, and established food co-ops. In <em>Stirrings</em>,<em> </em>Lana Dee Povitz draws on oral histories and archives to recount the stories of individuals who led these efforts. She highlights the successes of grassroots movements and reminds readers of the many women leaders in the New York food justice movement.</p>
18. The New American Farmer: Immigration, Race, and the Struggle for Sustainability by Laura-Anne Minkoff-Zern<p>In <em>The New American Farmer</em>, Laura-Anne Minkoff-Zern offers a look at farm labor in the U.S. Although most farm owners are white Americans, farm workers are overwhelmingly immigrants and people of color. In this book, Minkoff-Zern details the experiences of farm laborers who are becoming farm owners themselves and outlines the many barriers that workers must overcome during this transition. Through interviews with farmers and organizers, Minkoff-Zern shows that these farmers bring sustainable agricultural practices that can benefit our food system.</p>
19. The Story of More: How We Got to Climate Change and Where to Go from Here by Hope Jahren<p>Hope Jahren breaks down climate change for readers in an accessible and data-driven book. <em>The Story of More </em>explains<em> </em>how greenhouse gas emissions and consumption of natural resources in developed nations exacerbate climate change and outlines the consequences of these actions.

The COVID-19 pandemic has disrupted the U.S. recycling industry. Waste sources, quantities and destinations are all in flux, and shutdowns have devastated an industry that was already struggling.

Recyclers Under Pressure<p>Since March 2020, when most shelter-in-place orders began, sanitation workers have noted massive increases in municipal garbage and recyclables. For example, in cities like Chicago, workers have seen up to <a href="https://chicago.suntimes.com/coronavirus/2020/4/7/21212543/coronavirus-chicago-garbage-pickup-streets-sanitation-masks" target="_blank">50% more waste</a>.</p><p>According to the <a href="https://swana.org/" target="_blank">Solid Waste Association of North America</a>, U.S. cities saw a <a href="https://swana.org/news/swana-news/article/2020/06/17/swana-submits-statement-on-recycling-challenges-for-u.s.-senate-hearing" target="_blank">20% average increase</a> in municipal solid waste and recycling collection from March into April 2020. Increased trash can be attributed partly to spring cleaning, but most of it is due to people spending greater time at home. Restaurants struggling to survive under COVID-19 restrictions are contributing to the rise in plastic and paper waste with <a href="https://theconversation.com/using-lots-of-plastic-packaging-during-the-coronavirus-crisis-youre-not-alone-135553" target="_blank">takeout packaging</a>.</p><p>Although higher volumes of recyclables are being set on the curb, budget deficits are squeezing recycling programs. Many municipalities are struggling with <a href="https://www.ketv.com/article/omaha-mayor-health-officials-to-provide-covid-19-update-friday-afternoon/32498068#" target="_blank">multimillion-dollar shortfalls</a>. Some communities, such as Rock Springs, Wyoming, and East Peoria, Illinois, <a href="https://resource-recycling.com/recycling/2020/05/27/budget-shortfalls-threaten-local-recycling-programs/" target="_blank">have cut recycling programs</a>.</p><p>And these stresses are testing a business already faced uncertainty.</p>

Turmoil in Scrap Markets<p>The global recycling economy has suffered since 2018 as first China and then other Asian nations <a href="https://theconversation.com/as-more-developing-countries-reject-plastic-waste-exports-wealthy-nations-seek-solutions-at-home-117163" target="_blank">banned imports of low-quality scrap</a> — often meaning improperly cleaned food packaging and poorly sorted recyclable materials. As in any business, the value of raw recyclables is linked to supply and demand. Without demand from nations like China, which formerly took up to 700,000 tons of U.S. scrap annually, recyclers have scrambled to stay in business.</p><p>The pandemic has boosted prices for some materials. One industry leader told us that between February and May 2020, prices doubled for recycled paper and tripled for recycled cardboard. These shifts reflect higher demand for tissue products and shipping packaging under shelter-in-place orders.</p><p>However, he also reported that prices for the most-recycled categories of reclaimed plastics — PET (#1) and PE (#2 and #4) – were at 10-year lows. An influx of cheap oil has driven the raw material cost of oil-derived virgin plastics to their lowest levels in decades, <a href="https://millerrecycling.com/oil-prices-recycling#:%7E:text=Higher%20oil%20prices%20can%20also,robust%20market%20for%20recycled%20plastic." target="_blank">outcompeting recycled feedstocks</a>.</p>
Difficult Economics<p>Ideally, revenues from recycling offset municipalities' costs for collecting and disposing of solid wastes. However, given worker safety concerns, low market prices for scrap materials, a slowed economy and cheaper alternatives for disposal, many communities and businesses across the U.S. have <a href="https://www.wastedive.com/news/recycling-mrfs-prison-labor-suspensions-coronavirus-covid-19/574301/" target="_blank">temporarily suspended</a> collection of recyclables and bottle deposits.</p><p>Meanwhile, as the commercial sector slowed, the distribution of waste generation changed. As people have spent more time producing waste at home, waste collectors implemented <a href="https://www.wastedive.com/news/coronavirus-covid-waste-recycling-safety-collection-mrf/574359/" target="_blank">new procedures</a> to protect their employees from infection.</p><p>Recycling is a very hands-on process that requires workers to manually sort out items from the collection stream that are unsuitable for mechanical processing. Workers and waste collection companies have <a href="https://www.wastedive.com/news/coronavirus-covid-waste-recycling-safety-collection-mrf/574359/" target="_blank">raised many safety questions</a> about recycling during the pandemic.</p><p>Precautions like social distancing and use of personal protective equipment have become commonplace among waste collectors and sorters, though concerns remain. Sorters are increasingly relying on automation, but implementation can be costly and takes time.</p>
Collections on Pause<p>Based on monitoring since 2017 by the trade publication <a href="https://www.wastedive.com/news/curbside-recycling-cancellation-tracker/569250/" target="_blank">Waste Dive</a>, nearly 90 curbside recycling programs had experienced or continue to experience a prolonged suspension over the past several years. About 30 of these suspensions have occurred since January 2020.</p>
Like many bottle deposit programs, Kroger's Ann Arbor, Mich. drop-off center shut down on March 23. Michigan bottle deposits across the state resumed on June 15, 2020 with new safety protocols. Brian Love / CC BY-ND<p>On a broader scale, it's not clear how much more waste Americans are currently producing during shutdowns. Commercial and residential waste aren't directly comparable. For example, a granola bar wrapper thrown away at the office is tallied differently than if discarded at home.</p><p>It is also challenging to quantify the effects of the pandemic while it is still unfolding. Historically, waste output from the commercial and industrial sectors has far outweighed the municipal stream. With many offices and business closed or operating at low levels, total U.S. waste production could actually be at a record low during this time. However, data on commercial and industrial wastes are not readily available.</p><p>At the California-based <a href="https://resource-recycling.com/recycling/2020/04/28/city-data-shows-covid-19-impacts-on-recycling-tonnages/" target="_blank">Peninsula Sanitary Service</a>, which serves the Stanford University community, total tonnage was down 60% in March. The company attributes this drop to reduced commercial waste, particularly from construction. Similarly, the city of Vancouver, British Columbia, noted a <a href="https://www.cbc.ca/news/canada/british-columbia/metro-vancouver-garbage-decrease-covdi-19-1.5544942" target="_blank">10% decrease</a> year over year of waste collection levels for April.</p>

More Plastic Trash<p>As cities and industries reopen in the coming months, new data will show the pandemic's effects on consumer habits and waste generation. But regardless of total volume, the mix of materials in household wastes has shifted given the new ubiquity of single-use plastic containers, online shopping packaging and disposable gloves, wipes and face masks. Many of these new staples of pandemic life are made from plastics that are simply not worth recycling if there are any other disposal options.</p><p>Today Americans are trying to balance their physical well-being against ever-mounting piles of plastic waste. At a time when reducing and reusing could be dangerous, and recycling economics are unfavorable, we see a need for better options, such as more <a href="https://theconversation.com/bio-based-plastics-can-reduce-waste-but-only-if-we-invest-in-both-making-and-getting-rid-of-them-98282" target="_blank">compostable packaging</a> that is both safer and more sustainable.</p>
1. Processed ‘Low-Fat’ and ‘Fat-Free’ Foods<p>The "war" on <a href="https://www.healthline.com/nutrition/saturated-fat-good-or-bad/" target="_blank">saturated fat</a> could be considered one of the most misguided decisions in the history of nutrition.</p><p>It was based on weak evidence, which has now been completely <a href="https://www.healthline.com/nutrition/it-aint-the-fat-people/" target="_blank">debunked</a>.</p><p>When this discussion started, processed food manufacturers jumped on the bandwagon and started removing the fat from foods.</p><p>But there's a huge problem. Food doesn't taste well when the fat has been removed. That's why they added a lot of sugar to compensate.</p><p>Saturated fat is harmless, but added sugar is incredibly harmful when consumed in excess.</p><p>The words "low fat" or "fat free" on packaging usually means that it's a highly processed product that's loaded with sugar.</p>
2. Most Commercial Salad Dressings<p>Vegetables are incredibly healthy.</p><p>The problem is that they often don't taste very good on their own.</p><p>That's why many people use dressings to add flavor to their salads, turning these bland meals into delicious treats.</p><p>But many salad dressings are actually loaded with unhealthy ingredients like sugar, vegetable oils, and <a href="https://www.healthline.com/nutrition/why-trans-fats-are-bad/" target="_blank">trans fats</a>, along with various artificial chemicals.</p><p>Although vegetables are good for you, eating them with a dressing high in harmful ingredients negates any health benefit you get from the salad.</p><p>Check the ingredients list before you use a salad dressing or make your own using healthy ingredients.</p>
3. Fruit Juices … Which Are Basically Just Liquid Sugar<p>A lot of people believe <a href="https://www.healthline.com/nutrition/fruit-juice-is-just-as-bad-as-soda/" target="_blank">fruit juices</a> are healthy.</p><p>They must be because they come from fruit, right?</p><p>But most fruit juice you find in the grocery store isn't really fruit juice.</p><p>Sometimes they don't have any actual fruit in them, just chemicals that taste like fruit. What you're drinking is basically fruit-flavored sugar water.</p><p>That being said, even if you're drinking 100% quality fruit juice, it's still not the best choice.</p><p>Fruit juice is like fruit, except with all the good stuff (like the <a href="https://www.healthline.com/nutrition/why-is-fiber-good-for-you/" target="_blank">fiber</a>) taken out. The main thing left of the actual <a href="https://www.healthline.com/nutrition/is-fruit-good-or-bad-for-your-health/" target="_blank">fruit</a> is the sugar.</p><p>Fruit juice actually contains a similar amount of sugar as a sugar-sweetened beverage.</p>
4. ‘Heart-Healthy’ Whole Wheat<p>Most "whole wheat" products aren't really made from whole wheat.</p><p>The grains have been pulverized into very fine flour, which causes them to raise blood sugar just as fast as their refined counterparts.</p><p>In fact, whole wheat bread can have a similar glycemic index as white bread.</p><p>But even true whole wheat may be a bad idea because modern wheat is unhealthy compared to the wheat our grandparents ate.</p><p>Around 1960, scientists modified the genes in wheat to increase the yield. <a href="https://www.healthline.com/nutrition/modern-wheat-health-nightmare/" target="_blank">Modern wheat</a> is less nutritious and has some properties that make it much worse for people who have a gluten intolerance.</p><p>There are also studies showing that modern wheat may cause inflammation and increased cholesterol levels, at least when compared to the older varieties.</p><p>Wheat may have been a relatively healthy grain back in the day, but the stuff most people are eating today should be consumed with caution.</p>
5. Cholesterol-Lowering Phytosterols<p>Phytosterols are nutrients that are basically like plant versions of cholesterol.</p><p>Some studies have shown that they can lower blood cholesterol in humans.</p><p>For this reason, they're often added to processed foods that are then marketed as "cholesterol lowering" and claimed to help prevent heart disease.</p><p>However, studies have shown that despite lowering cholesterol levels, phytosterols have negative effects on the cardiovascular system and may even increase the risk of heart disease and death.</p><p>People with phytosterolaemia (a genetic condition that raises plant sterol level in blood) are more susceptible to the negative effects of phytosterols.</p>
6. Margarine<p><a href="https://www.healthline.com/nutrition/7-reasons-why-butter-is-good-for-you/" target="_blank">Butter</a> was labeled a bad food choice in the past because of its high saturated fat content.</p><p>Various health experts started promoting margarine instead.</p><p>Back in the day, margarine used to be high in trans fats. These days, it has fewer trans fats than before, but it's still loaded with refined vegetable oils.</p><p>Not surprisingly, the Framingham Heart Study <a href="https://www.healthline.com/nutrition/butter-vs-margarine/" target="_blank">showed</a> that people who replace butter with margarine are actually more likely to die from heart disease.</p><p>If you want to improve your health, try to eat real butter (preferably <a href="https://www.healthline.com/nutrition/grass-fed-butter-superfood-for-the-heart/" target="_blank">grass fed</a>), and avoid margarine with trans fat. Trans-fat-free margarine has become more available in recent years.</p><p>Always read nutrition facts carefully and limit products that contain trans fat.</p><p>Recommending trans fat-laden margarine instead of natural butter may be considered some of the worst nutrition advice in history.</p>
7. Sports Drinks<p>Sports drinks were designed with athletes in mind.</p><p>They contain electrolytes (salts) and sugar, which can be useful for athletes in many cases.</p><p>However, most people don't need additional salt or liquid sugar in their diet.</p><p>Although often considered "less bad" than sugary soft drinks, there's really no fundamental difference in the two, except the sugar content in sports drinks is sometimes <em>slightly</em> lower.</p><p>It's important to stay hydrated, especially when working out, but most people will be better off sticking to plain <a href="https://www.healthline.com/nutrition/how-much-water-should-you-drink-per-day/" target="_blank">water</a>.</p>
8. Low-Carb Junk Foods<p><a href="https://www.healthline.com/nutrition/low-carb-diet-meal-plan-and-menu/" target="_blank">Low carb diets</a> have been incredibly popular for many decades.</p><p>In the past 12 years, <a href="https://www.healthline.com/nutrition/23-studies-on-low-carb-and-low-fat-diets/" target="_blank">studies</a> have confirmed that these diets are an effective way to lose weight and improve health.<a href="http://onlinelibrary.wiley.com/doi/10.1111/j.1467-789X.2008.00518.x/abstract" target="_blank"></a></p><p>However, food manufacturers have caught up on the trend and brought various low carb "friendly" processed foods to the market.</p><p>This includes highly processed foods like the <a href="https://www.healthline.com/nutrition/are-atkins-low-carb-bars-healthy/" target="_blank">Atkins bars</a>. If you take a look at the ingredients list, you see that there's no real food in them, just chemicals and highly refined ingredients.</p><p>These products can be consumed occasionally without compromising the metabolic adaptation that comes with low carb eating.</p><p>However, they don't really nourish your body. Even though they're technically low carb, they're still unhealthy.</p>
9. Agave Nectar<p>Given the known <a href="https://www.healthline.com/nutrition/10-disturbing-reasons-why-sugar-is-bad/" target="_blank">harmful effects</a> of sugar, people have been looking for alternatives.</p><p>One of the more popular "natural" sweeteners is agave nectar, which is also called agave syrup.</p><p>You'll find this sweetener in all sorts of "healthy foods," often with attractive claims on the packaging.</p><p>The problem with agave is that it's no better than regular sugar. In fact, it's much worse.</p><p>One of the main problems with sugar is that it has excessive amounts of <a href="https://www.healthline.com/nutrition/why-is-fructose-bad-for-you/" target="_blank">fructose</a>, which can cause severe metabolic problems when consumed in excess.</p><p>Sugar is about 50% fructose and 55% high fructose corn syrup, but agave contains even more — up to 70-90%.</p><p>Therefore, gram for gram, agave is even worse than regular sugar.</p><p>"Natural" doesn't always equal healthy. Whether agave should even be considered natural is debatable.</p>
10. Vegan Junk Foods<p>Vegan diets are very popular these days, often due to ethical and environmental reasons.</p><p>However, many people promote vegan diets for the purpose of improving health.</p><p>There are many processed vegan foods on the market, often sold as convenient replacements for non-vegan foods.</p><p>Vegan bacon is one example.</p><p>But it's important to keep in mind that these are usually highly processed, factory made products that are bad for almost anyone, including people who are vegan.</p>
11. Brown Rice Syrup<p><a href="https://www.healthline.com/nutrition/brown-rice-syrup-good-or-bad/" target="_blank"><br>Brown rice syrup</a>, also known as rice malt syrup, is a sweetener that's mistakenly assumed to be healthy.</p><p>It's made by exposing cooked rice to enzymes that break down the starch into simple sugars.</p><p>Brown rice syrup contains no refined fructose, just glucose.</p><p>The absence of refined fructose is good, but rice syrup has a glycemic index of 98, which means that the glucose in it will spike blood sugar extremely fast.<a href="http://www.glycemicindex.com/foodSearch.php?num=2648&ak=detail" target="_blank"></a></p><p>Rice syrup is also highly refined and contains almost no essential nutrients. In other words, it's considered "empty" calories.</p><p>Some concerns have been raised about arsenic contamination in this syrup, which is another reason to be extra careful with this sweetener.</p><p>There are other sweeteners out there, including low calorie sweeteners like:</p><ul><li><a href="https://www.healthline.com/nutrition/stevia/" target="_blank">stevia</a></li><li><a href="https://www.healthline.com/nutrition/erythritol/" target="_blank">erythritol</a></li><li><a href="https://www.healthline.com/nutrition/xylitol-101/" target="_blank">xylitol</a></li></ul><p>In general, try to use all sweeteners wisely and follow recommended serving sizes.</p>
12. Processed Organic Foods<p>Unfortunately, the word "organic" has become a typical marketing buzzword in many instances.</p><p>Food manufacturers have found all sorts of ways to make the same products, except with ingredients that happen to be organic.</p><p>This includes ingredients like organic raw cane sugar, which is basically 100% identical to regular sugar. It's still just glucose and fructose with little to no nutrients.</p><p>In many cases, the difference between an ingredient and its organic counterpart is next to none.</p><p>Processed foods that happen to be labeled organic aren't necessarily healthy. Always check the label to see what's inside.</p>
13. Vegetable Oils<p>We're often advised to eat seed and vegetable oils, which includes soybean oil, <a href="https://www.healthline.com/nutrition/canola-oil-good-or-bad/" target="_blank">canola oil</a>, <a href="https://www.healthline.com/nutrition/grape-seed-oil/" target="_blank">grapeseed oil</a>, and numerous others.</p><p>This recommendation is based on the fact that these oils have been shown to lower blood cholesterol levels, at least in the short term.<a href="https://pubmed.ncbi.nlm.nih.gov/23731447/" target="_blank"></a></p><p>However, it's important to keep in mind that blood cholesterol is a <em>risk factor</em>. It's not a disease in itself.</p><p>Even though vegetable oils can help improve a risk factor, there's no guarantee that they'll help prevent actual health outcomes like heart attacks or death, which is what really counts.</p><p>In fact, several controlled trials have shown that despite lowering cholesterol, these oils can increase the risk of developing heart disease and memory impairment.</p><p>It's important to eat healthy, natural fats like butter, <a href="https://www.healthline.com/nutrition/top-10-evidence-based-health-benefits-of-coconut-oil/" target="_blank">coconut oil</a> and <a href="https://www.healthline.com/nutrition/extra-virgin-olive-oil/" target="_blank">olive oil</a> in moderation.</p><p>Also, follow the recommended serving size, but limit processed <a href="https://www.healthline.com/nutrition/are-vegetable-and-seed-oils-bad/" target="_blank">vegetable oils</a> as if your health depended on it, which it does.</p>
14. Gluten-Free Junk Foods<p>According to a <a href="http://www.npd.com/wps/portal/npd/us/news/press-releases/percentage-of-us-adults-trying-to-cut-down-or-avoid-gluten-in-their-diets-reaches-new-high-in-2013-reports-npd/" target="_blank">2013 survey</a>, about a third of people in the United States are actively trying to limit or avoid gluten.</p><p>Many experts believe this is unnecessary, but the truth is, <a href="https://www.healthline.com/nutrition/6-shocking-reasons-why-gluten-is-bad/" target="_blank">gluten</a>, especially from modern wheat, can be problematic for a lot of people.</p><p>Not surprisingly, the food manufacturers have brought <em>all sorts</em> of gluten-free foods to the market.</p><p>The problem with these foods is that they usually have the same negative effects on your body as their gluten-containing counterparts, if not worse.</p><p>These are highly processed foods containing few nutrients and often made with refined starches that can lead to very rapid spikes in blood sugar.</p><p>Try to choose foods that are naturally gluten free, like plants and animals, not gluten-free processed foods.</p><p>Gluten-free junk food is still junk food.</p>
15. Most Processed Breakfast Cereals<p>The way some breakfast cereals are marketed can be deceiving.</p><p>Many of them, including those that are marketed toward children, have various health claims listed on the box.</p><p>This includes claims like "whole grain" or "low fat" that may be misleading.</p><p>This is especially true when you look at the ingredients list and see that these products mostly contain:</p><ul><li>refined grains</li><li>sugar</li><li>artificial chemicals</li></ul><p>It's important to always review product packaging to confirm what you're actually putting in your body and whether it's healthy for you.</p><p>Truly healthy foods are whole, single-ingredient foods. Their health benefits speak for them.</p><p>Real food doesn't even need an ingredients list, because real food is the ingredient.</p>

Human actions have taken a steep toll on whales and dolphins. Some studies estimate that small whale abundance, which includes dolphins, has fallen 87% since 1980 and thousands of whales die from rope entanglement annually. But humans also cause less obvious harm. Researchers have found changes in the stress levels, reproductive health and respiratory health of these animals, but this valuable data is extremely hard to collect.

A Lot to Learn From Hormones<p>When sampling the blow, we are looking for hormones in mucus as these can be used to gauge psychological and physiological health. We are specifically interested in <a href="https://dx.doi.org/10.1371%2Fjournal.pone.0114062" target="_blank">hormones like cortisol</a> and <a href="https://doi.org/10.1016/j.ygcen.2018.04.003" target="_blank">progesterone</a>, which indicate stress levels and reproductive ability respectively, but can also help determine overall health.</p><p>Additionally, blow samples can detect <a href="https://dx.doi.org/10.1128%2FmSystems.00119-17" target="_blank">respiratory pathogens</a> in the lungs or nasal passages - blowholes evolved from noses after all.</p><p>This health analysis is especially important in areas with oil spills as the chemicals can cause hormonal problems that harm <a href="https://www.carmmha.org/investigating-how-oil-spills-affect-dolphins-and-whales/" target="_blank">development, metabolism and reproduction</a> in dolphins.</p><p>Hormone samples can provide scientists with valuable data, but collecting them from intelligent and unpredictable animals is challenging.</p>
Cetacean Collaborators<p>To build a drone that can stealthily collect spray from moving dolphins, we needed more data on their eyesight and hearing, and this is data that couldn't be collected in the wild nor simulated in a lab.</p><p>We worked with dolphins at facilities like Dolphin Quest in Bermuda, which provides guests opportunities to learn about dolphins while allowing <a href="https://dolphinquest.com/about-us/our-story/" target="_blank">scientists access to animals for noninvasive research</a>. Here the dolphins can swim away if they choose not to work with us, so we had to design the study like a game; the way a kindergarten teacher entertains a class. If the dolphins aren't interested, we don't get to do the science.</p><p>Over the course of hundreds of sessions, we sought to answer two questions: What can dolphins hear and what can they see around their heads?</p><p>To test dolphin hearing, we set up microphones and cameras to record dolphin behavior as we played drone noise in the air. We analyzed the responses to each noise – such as how many dolphins looked at the speaker – and used these as a proxy for their ability to hear the sounds.</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="5f31daf07a652b8d64a093b993ee4e96"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/UjmQeH3vXHI?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
Robodolphin doesn't look like a real dolphin, but it doesn't need to in order to train our drone pilots. C.J. Barton / Oklahoma State University / CC BY-ND<p>To build robodolphin, we worked with dolphins trained to "chuff" or sneeze on command to measure spray characteristics. We used high-speed photography to see the dolphins' breath as it moved through the air. Then we conducted high resolution CT scans of a dolphin head and 3D-printed a replica of a nasal passage.</p><p>Now, we have a complete robodolphin and are tweaking its sprays to be nearly identical to the real thing. This will allow us to determine how close we need to get to collect the samples, and therefore, how quiet our drone needs to be.</p>
The replica dolphin blowhole was designed from a scan of a real blowhole passage, and the spray it produces closely matches the real thing. Alvin Ngo, Mitch Ford and CJ Barton / Oklahoma State University / CC BY-ND
A Bit of Practice, Then Into the Wild<p>In the next few months, we will test flights over robodolphin with existing drones to determine the timing and strategy for collection. From there, we will fabricate a low-noise drone that can fly fast enough and with sufficient maneuverability to capture samples from wild dolphins. Like a video game, we will use the visual field data to develop approach trajectories to stay in the visual blindspots.</p><p>We plan to test our drones on a truck-mounted robodolphin moving down a runway, then using a boat to simulate realistic conditions. The next steps will involve ocean testing with dolphins trained for open ocean swimming. These tests will determine if our devices can catch and hold the hormones as the drone flies back to a researcher's boat.</p><p>Finally, we will deploy the system to collect data on wild dolphins. Our first goal is to test resident dolphins – animals that live on the coasts and deal directly with boat and oil industry noise – which will allow us to learn more about stress resulting from human impacts.</p><p>Those samples are a way off, but if all goes well we will have a specially built drone capable of flying long distances and capturing samples undetected in a few years. The samples collected will allow researchers to do better science with impact on the animals they study.</p>
