Every activist engaged in combating human-caused climate change or specific elements of the current energy economy knows that the work is primarily oppositional. It could hardly be otherwise. For citizens who care about ecological integrity, a sustainable economy and the health of nature and people, there is plenty to oppose—biomass logging in Massachusetts, mountaintop-removal coal mining in West Virginia, natural gas drilling in Wyoming, poorly sited solar developments in California, river-killing dams in Chile and Brazil, and new nuclear and coal plants around the globe.
These and many other fights against destructive energy projects are crucial, but they can be draining and tend to focus the conversation in negative terms. Sometimes it’s useful to reframe the discourse about ecological limits and economic restructuring in positive terms, that is, about what we’re for. The following list is not comprehensive, but beauty and biodiversity are fundamentals that the energy economy must not diminish. And energy literacy, conservation, relocalization of economic systems, and family planning are necessary tools to achieve our vision of a day when resilient human communities are imbedded in healthy ecosystems, and all members of the land community have space enough to flourish.
Energy is arguably the most decisive factor in both ecosystems and human economies. It is the fulcrum of history, the enabler of all that we do. Yet few people have more than the sketchiest understanding of how energy makes the world go ’round.
Basic energy literacy consists of a familiarity with the laws of thermodynamics, and with the concepts of energy density and energy returned on energy invested (EROEI). It requires a familiarity with the costs and benefits of our various energy sources—including oil, coal, gas, nuclear, wind and solar. It also implies numeracy—the ability to meaningfully compare numbers referring to quantities of energy and rates of use, so as to be able to evaluate matters of scale.
Without energy literacy, citizens and policy makers are at the mercy of interest groups wanting to sell us their vision of the future energy economy. We hear from the fossil fuel industry, for example, that Canada’s oil reserves (in the form of “tar sands”) are second only to Saudi Arabia’s, or that the U.S. has more than 100 years of natural gas thanks to newly tapped “shale gas” resources. And it’s tempting to conclude (as many people do) that there are no real constraints to national fossil fuel supplies other than environmental regulations preventing the exploitation of our immense natural treasures.
On the other end of the spectrum, we hear from techno-optimists that, with the right mix of innovative energy generation and efficiency technologies, we can run the growth economy on wind, solar, hydropower and biofuels. And it’s tempting to conclude that we only need better government incentives and targeted regulatory reform to open the floodgates to a “green” high-tech sustainable future.
Energy literacy arms us with the intellectual tools to ask the right questions—What is the energy density of these new fossil fuel resources? How much energy will have to be invested to produce each energy unit of synthetic crude oil from oil shale, or electricity from thin-film solar panels? How quickly can these energy sources be brought online, and at what rate can they realistically deliver energy to consumers? When we do ask such questions, the situation suddenly looks very different. We realize that the new fossil fuels are actually third-rate energy sources that require immense and risky investments and may never be produced at a significant scale. We find that renewable energy technologies face their own serious constraints in energy and materials needs, and that transitioning to a majority-renewable energy economy would require a phenomenal re-tooling of our energy and transportation infrastructure.
With energy literacy, citizens and policy makers have a basis for sound decisions. Householders can measure how much energy they use and strategize to obtain the most useful services from the smallest energy input. Cities, states and nations can invest wisely in infrastructure both to produce and use energy with greatest efficiency and with minimal damage to the natural world. With energy literacy, we can undertake a serious, clear-eyed societal conversation about the policies and actions needed to reshape our energy system.
The current energy economy is toxic not simply because of its dependence on climate-altering fossil fuels, but also because of its massive scale and wastefulness. A first step toward reducing its global impacts is simply using less energy, a goal readily accomplished through conservation practices that are widely available and cost effective.
Energy conservation consists of two distinct strategies—efficiency and curtailment. Energy efficiency means using less energy to produce a similar or better service. For example, we can exchange old incandescent light bulbs for compact fluorescents or LEDs that use a fraction of the electricity and still enjoy satisfactory levels of indoor illumination.
Curtailment means exactly what you’d think—cutting out a use of energy altogether. In our previous example of indoor lighting, this strategy might take the form of turning off the lights when we leave a room.
Efficiency is typically more attractive to people because it doesn’t require them to change their behavior. We want services that energy provides us, not energy per se, and if we can still have all the services we want, then who cares if we’re using less energy to get them? Much has been achieved with energy efficiency efforts over recent decades, but much more remains to be done—nearly all existing buildings need to be better insulated, and most electric power plants are operating at comparatively dismal efficiencies, to mention just two examples.
Unfortunately, increasing investments in energy efficiency typically yield diminishing returns. Initial improvements tend to be easy and cheap; later ones are more costly. Sometimes the energy costs of retooling or replacing equipment and infrastructure wipe out gains from efficiency. Nevertheless, the early steps toward efficiency are almost always rewarding.
While curtailment of energy use is a less inviting idea, it offers clearer savings as compared with improved efficiency. By simply driving fewer miles we unequivocally save energy, whether our car is a more or less efficient model. We’ve gotten used to using electricity and fuels to do many things that can be done by well enough with muscle power, or that don’t need doing at all.
Conservation helps us appreciate the energy we use. It fosters respect for resources, and for the energy and labor that are embodied in manufactured products. It reduces damage to already stressed ecosystems and helps us focus our attention on dimensions of life other than sheer consumption.
During the latter decades of the 20th century, most Americans achieved a standard of living that was lavish from both historical and cross-cultural perspectives. They were coaxed and cajoled from cradle to grave by expensive advertising to consume as much as possible. Simply by reversing the message of this incessant propaganda stream, people can be persuaded to happily make do with less—as occurred during World War II, when fuels were rationed and billboards promoted recycling.
Many social scientists claim that our consumptive lifestyle damages communities, families and individual self-esteem. A national or global ethic of conservation could even be socially therapeutic.
Resilience is “the capacity of a system to withstand disturbance while still retaining its fundamental structure, function and internal feedbacks.” Resilience contrasts with brittleness—the tendency to shatter and lose functionality when impacted or perturbed.
Ecologists who study resilience in natural systems have noted that ecosystems tend to progress through a series of phases—growth, consolidation and conservation, release (or “collapse”), and reorganization. Each turning of this adaptive cycle provides opportunities for individual species and whole systems to innovate in response to external and internal change (i.e., disturbance). Resilient ecosystems (in the early growth phase) are characterized by species diversity; many of the organisms within such systems are flexible generalists, and the system as a whole contains multiple redundancies. In contrast, less-resilient ecosystems tend to be more brittle, showing less diversity and greater specialization particularly in the consolidation phase.
Resilience can be applied to human systems as well. Our economic systems, in particular, often face a trade-off between resilience and efficiency. Economic efficiency implies specialization and the elimination of both inventories and redundancy (which typically guarantee greater resilience). If a product can be made most cheaply in one region or nation, manufacturing is concentrated there, reducing costs to both producers and consumers. However, if that nation were to suddenly find it impossible to make or ship the product, that product would become unavailable everywhere. Maintaining dispersed production and local inventories promotes availability under crisis conditions, though at the sacrifice of economic efficiency (and profits) in “normal” times.
From a resilience perspective one of the most vulnerable human systems today is the American transportation system. For over seventy years we’ve built trillions of dollars of transportation infrastructure that is completely dependent (i.e., “specialized”) on affordable petroleum fuels, and we’ve removed or neglected most alternative methods of transport. As petroleum fuels become less affordable, the effects reverberate throughout the system.
Resilience becomes more of a priority during periods of crisis and volatility, such as the world is experiencing today. Households, towns and regions are better prepared to endure a natural disaster such as a flood or earthquake if they have stores of food and water on hand and if their members have a range of practical self-sufficiency skills.
While the loss of economic efficiency implies trade-offs, resilience brings incidental benefits. With increased local self-sufficiency comes a shared sense of confidence in the community’s ability to adapt and endure. For the foreseeable future, as global energy, finance and transport systems become less reliable, the re-balancing of community priorities should generally weigh in favor of resilience.
A central strategy needed to increase societal resilience is localization—or, perhaps more accurately, re-localization. Most pre-industrial human societies produced basic necessities locally. Trade typically centered on easily transportable luxury goods. Crop failures and other disasters therefore tended to be limited in scope—if one town was devastated, others were spared because they had their own regional sources—and stores—of necessities.
Economic globalization may have begun centuries ago with the European colonization of the rest of the world, but really took hold during the past half-century with the advent of satellite communications and container ships. The goal was to maximize economic growth by exploiting efficiency gains from local specialization and global transport. In addition to driving down labor costs and yielding profits for international corporations, globalization maximized resource depletion and pollution, simplified ecosystems and eroded local systems resilience.
As transport fuel becomes less affordable, a return to a more localized economic order is likely, if not inevitable. The market’s methods of re-balancing economic organization, however, could well be brutal as global transport networks become less reliable, transport costs increase, and regions adapt to less access to goods now produced thousands of miles away.
Government planning and leadership could result in a more organized and less chaotic path of adaptation. Nations can begin now to prioritize and create incentives for the local production of food, energy and manufactured products, and the local development of currency, governance, and culture.
Natural ecological boundaries—such as watersheds—bordered traditional societies. Bioregions defined by waterways and mountain ridges could thus become the basis for future re-localized economic and political organization.
Deliberate efforts to re-localize economies will succeed best if the benefits of localism are touted and maximized. With decentralized political organization comes greater opportunity for participation in decision-making. Regional economic organization offers a wide variety of productive local jobs. Society assumes a human scale in which individuals have a sense of being able to understand and influence the systems that govern their lives. People in locally organized societies see the immediate consequences of their production and waste disposal practices, and are therefore less likely to adopt an “out of sight, out of mind” attitude toward resource depletion and pollution. Local economic organization tends to yield art, music, stories and literature that reflect the ecological uniqueness of place—and local culture in turn binds together individuals, families and communities, fostering a sense of responsibility to care for one another and for the land.
The human demographic explosion, amplified by rapacious consumption in the overdeveloped world, is at the root of the global eco-social crisis. Virtually every environmental and social problem is worsened by overpopulation. With more mouths to feed—and freshwater becoming scarcer and topsoil eroding—global famine becomes an ever-greater likelihood. An expanding population leads to increased consumption of just about every significant resource, and thus to increasing rates of ecological damage, from deforestation to climate change.
Family planning helps avert those threats. If we want future generations to enjoy a healthy planet with wild spaces, biodiversity, abundant resources, and a livable climate, we should reduce fertility now.
But family planning can do more than mitigate future resource depletion; it has direct and in some cases nearly immediate benefits. Some of those benefits are economic. For example, Ireland’s declining birth rate in the 1970s is often credited as one of the factors leading to its economic boom in the ’80s and ’90s. China’s one-child policy similarly contributed to its economic ascendancy. The mechanism? In poor societies where family size is typically large, all household income must go toward food and shelter, and none is left over for education and business formation. If the birth rate is reduced, household income is freed up to improve quality of life and economic prospects for the next generation.
Without access to contraceptives, the average woman would have 12 to 15 pregnancies in her lifetime. In contrast, women in industrial nations want, on average, only two children.
It turns out that when women are economically and, this is critical, culturally empowered to make decisions about their own fertility, the result is improved health for mother and children, fewer unplanned pregnancies and births, and reduced incidence of abortion. Numerous studies have shown that women who have control over their fertility also tend to have more educational and employment opportunities, enhancing their social and economic status and improving the well-being of their families.
Discussions about energy rarely focus on beauty. But the presence or absence of this ineffable quality offers us continual clues as to whether or not society is on a regenerative and sustainable path, or on the road to further degradation of nature’s integrity.
From the time of the earliest cave paintings, human ideals of beauty have been drawn from nature. Animals, plants, rivers, oceans and mountains all tend to trigger a psychological response describable as pleasure, awe and wonder. The sight of a great tree or the song of a goldfinch can send poets and mystics into ecstasy, while the deep order inherent in nature inspires mathematicians and physicists.
Nature achieves its aesthetic impact largely through anarchic means. Each part appears free to follow its own inner drives, exhibiting economy, balance, color, proportion and symmetry in the process. And all of these self-actualizing parts appear to cooperate, with multiple balancing feedback loops maintaining homeostasis within constantly shifting population levels and environmental parameters. The result is beauty.
Ugliness, by contrast, is our unpleasant aesthetic response to the perception that an underlying natural order has been corrupted and unbalanced; that something is dreadfully out of place.
Beauty is a psychological and spiritual need. We seek it everywhere, and wither without it. We need beauty not as an add-on feature to manufactured products, but as an integral aspect of our lives.
With the gradual expansion of trade—a process that began millennia ago but that quickened dramatically during the past century—beauty has increasingly become a valuable commodity. Wealthy patrons pay fortunes for rare artworks, while music, fashion, architecture and industrial design have become multi-billion-dollar industries. Nature produces the most profound, magnificent and nurturing examples of beauty in endless abundance, for free.
Industrialism, resulting from high rates of energy use, tends to breed ugliness. Our ears are bombarded by the noise of automobiles and trucks to the point that we can scarcely hear birdsong. The visual blight of highways, strip malls and box stores obscures natural vistas. With industrial-scale production of buildings, we have adopted standardized materials produced globally to substitute for local, natural materials that fit with their surroundings. But industrialism does not just replace and obscure natural beauty—it actively destroys it, gobbling up rivers and forests to provide resources for production and consumption.
Large-scale energy production—whether from coalmines and power plants, oil derricks and refineries, or massive wind and solar installations—comes at a cost of beauty. While some energy sources are inherently uglier than others, even the most benign intrudes, dominates and depletes if scaled up to provide energy in the quantities currently used in highly industrialized nations.
The aesthetic impact of industrial processes can be mitigated somewhat with better design practices. But the surest path to restoring the beauty of nature is to reduce the scale of human population and per-capita production and consumption. Returning to a sustainable way of life need not be thought of as sacrifice; instead it can be seen as an opportunity to increase aesthetic pleasure and the spiritual nourishment that comes from living in the midst of incalculable beauty.
The family of life on Earth is very large—more than a million species have been identified and formally described by taxonomists, and estimates of the total number of species on the planet range between three and one hundred million. We humans depend for our very existence on this web of life of which we are a part. Indeed, it is part of us—each human is inhabited by hundreds of species of microbes that enable digestion and other basic functions. Yet through our species’ appropriation and destruction of natural habitat we are shredding microbial, forest, prairie, oceanic, riparian, desert and other ecosystems. Habitat loss, overharvesting, climate change, and other results of human numbers and behavior endanger untold thousands of species with extinction.
Extinction is nothing new—it is an essential part of the process of evolution. Throughout the billions of years of life’s history, life forms have appeared, persisted for thousands or millions of years, and vanished, usually individually but occasionally in convulsive mass events triggered by geological or astrophysical phenomena. There were five ancient extinction events so catastrophic that 50 to 95 percent of all species died out.
Today, humans are bringing about the sixth mass extinction in the history of life on Earth. While the normal rate of extinction is about one in a million species per year, the extinction rate today is roughly 1000 times that. According to recent studies, one in five plant species faces extinction as a result of climate change, deforestation and urban growth. One of every eight bird species will likely be extinct by the end of this century, while one third of amphibian and one quarter of mammal species are threatened.
As species disappear, we are only beginning to understand what we are losing. A recent U.N. study determined that businesses and insurance companies now see biodiversity loss as presenting a greater risk of financial loss than terrorism—a problem that governments currently spend hundreds of billions of dollars per year to contain or prevent.
Non-human species perform ecosystem services that only indirectly benefit our kind, but in ways that often turn out to be crucial. Phytoplankton, for example, are not a direct food source for people, but comprise the base of oceanic food chains, in addition to supplying half of the oxygen produced each year by nature. The abundance of plankton in the world’s oceans has declined 40 percent since 1950, according to a recent study, for reasons not entirely clear. This is one of the main explanations for a gradual decline in atmospheric oxygen levels recorded worldwide.
Efforts to determine a price for the world’s environmental assets have concluded that the annual destruction of rainforests alone entails an ultimate cost to society of $4.5—$650 trillion for each person on the planet. Many species have existing or potential economically significant uses, but the value of biodiversity transcends economics—the spiritual and psychological benefits to humans of interaction with other species are profound.
Most fundamentally, however, non-human species have intrinsic value. Shaped by the same forces that produced humanity, our kin in the community of life exist for their own sake, not for the pleasure or profit of people. It is the greatest moral blot, the greatest shame on our species, for our actions to be driving other life forms into the endless night of extinction.

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.

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.

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>
