Bernie Sanders to College Graduates: Take on the Fossil Fuel Industry, Transform Our Energy System
By Jon Queally
Sen. Bernie Sanders delivered the commencement address at Brooklyn College on Tuesday and told graduating students that entering an "oligarchic" society, like one the U.S. is fast becoming, will demand vigilance and perseverance on their parts but that it was because of determined young people that he has "enormous confidence" in the country's ultimate future.
Sanders recounted learning about "oligarchic societies" when he was a high school student in Brooklyn. Described to him as "small developing countries" in which the "economic and political life of the nation were controlled by a handful of very wealthy people," Sanders admitted it "never occurred to me as a kid in Brooklyn that the United States of America, our great nation, could move in that direction." But, he added, "that is precisely ... what is happening today."

While commending graduating students and their parents for often working multiple jobs in order to make ends meet, Sanders lamented that more than fifty percent of all new income now "goes to the top one percent" of earners.
And in order to disrupt and combat such a system, Sanders said that throwing up your hands and giving up was simply not a viable option.
"The truth is that the only rational choice we have, the only real response we can make is to stand up and fight back—reclaim American democracy and create a government that works for all of us, not just the one percent," he said. "And for us to do that it is necessary that we fight for a vision of a new America. An America based on progressive, humane values, not the values of the oligarchy."
As he railed against economic inequality and a system rigged in favor of the wealthy and powerful, Sanders told students that unity would be key in order to defeat the destructive forces represented by President Donald Trump.
Sanders referenced his Jewish heritage and his family's experience with the Holocaust in Europe, which he said offered important lessons for "tough times" like these.
"From that experience, what was indelibly stamped on my mind was the understanding that we must never allow demagogues to divide us up by race, by religion, by national origin, by gender or sexual orientation," Sanders said to wide applause. "Black, white, Latino, Asian American, Native American, Christian, Jew, Muslim and every religion, straight or gay, male or female—we must stand together. This country belongs to all of us."
Sanders concluded on a message of hope, telling the graduates that Americans are "prepared to stand together; if we take on greed and selfishness; if we refuse to allow demagogues to divide us up there is no end to what the great people of our nation can accomplish."

The full transcript of Sanders remarks follows:
You know and I know that these are tough times for our country. But I do want to say that standing up here and looking out at the beautiful people in front of me, I have enormous confidence in the future of our country.
Let me begin by congratulating the graduating class of 2017. Today is an important day in your lives, something that I know you have worked very hard to achieve, and I want to wish all of you the very best of luck in your future endeavors.
I do want, on behalf of my wife, Jane, and myself, to pray that you all live healthy and happy lives, doing the work you enjoy surrounded in love by family and friends.
Let me thank President Michelle Anderson, Nicole Haas, the Brooklyn College Administration, faculty and staff and all of you for inviting Jane and me back to Brooklyn where we were both born and raised. I am greatly honored of the honorary degree you have given me.
I grew up in Flatbush and, like Senator Schumer, graduated from James Madison High School. My wife, Jane, was also raised Flatbush and Bedford-Stuyvesant, and graduated from St. Savior's High School a few miles away from here.
In 1959, as a first-generation college student I attended Brooklyn College for a year—a year which had a major impact in my life. After that year I left for the University of Chicago, where I eventually graduated. My mom had died the previous year and I felt it was time to leave the neighborhood and see what the rest of the world looked like.
My childhood in Brooklyn was shaped by two profound realities. First, my mom, dad and older brother, who graduated from Brooklyn College, lived in a 3 1/2 room rent-controlled apartment. As with many of your families who don't have a lot of money, financial pressures caused friction and tension within our household. From those experiences of growing up without a lot of money, I have never forgotten that there are millions of people throughout this country who struggle to put food on the table, pay the electric bill, try to save for their kids' education or for retirement—people who against great odds are fighting today to live in dignity.
The second reality that impacted my life was that my father left Poland at the age of 17 from a community which was not only very poor, but from a country where anti-Semitism, pogroms and attacks on Jews were not uncommon. While my father emigrated to the United States, and escaped Hitler and the Holocaust, many in his family did not. For them, racism, right-wing extremism and ultra-nationalism were not "political issues." They were issues of life and death—and some of them died horrific deaths.
From that experience, what was indelibly stamped on my mind was the understanding that we must never allow demagogues to divide us up by race, by religion, by national origin, by gender or sexual orientation. Black, white, Latino, Asian American, Native American, Christian, Jew, Muslim and every religion, straight or gay, male or female, we must stand together. This country belongs to all of us.
As a United States senator from Vermont let me give you a very brief overview of some of the serious crises we currently face—crises which do not often get attention they deserve.
As a student at James Madison High School, many years ago, I recall my social studies teacher talking about how there were small developing countries around the world that were "oligarchic" societies—places where the economic and political life of the nation were controlled by a handful of very wealthy people. It never occurred to me as a kid in Brooklyn that the United States of America, our great nation, could move in that direction. But that is precisely, in my view, what is happening today.
Today, the top one-tenth of one percent now owns almost as much wealth as the bottom 90 percent. Twenty Americans now own as much wealth as the bottom half of America and one family now owns more wealth than the bottom 42 percent of our people. In the last 17 years, while the middle class continues to decline, we have seen a tenfold increase in the number of billionaires. Today in America CEOs are earning almost 350 times more than the average worker makes. In terms of income, while you and your parents are working in some cases two or three jobs, 52 percent of all new income goes to the top one percent.
At the same time as we have more income and wealth inequality than any other major nation, 43 million Americans live in poverty, we have the highest rate of childhood poverty of almost any major country in earth, half of older workers have nothing in the bank as they approach retirement and in some inner cities and rural communities, youth unemployment is 20, 30, 40 percent. Unbelievably, in our country today as a result of hopelessness and despair we are seeing a decline in life expectancy. People are giving up. And they're turning to drugs, to alcohol, and even to suicide. And because of poverty, racism today in a broken criminal justice system we have more people in jail than any other country on Earth. Those people are disproportionately black, Latino and Native American.
Directly related to the oligarchic economy that we currently have is corrupt political system which is undermining American democracy and it's important we talk about that and understand that. As a result of the disastrous Citizens United Supreme Court decision, corporations and billionaires are able to spend unlimited sums of money on elections. The result is that today a handful of billionaires are spending hundreds of millions of dollars every single year, often on ugly 30-second TV ads, helping to elect candidates who represent the rich and the powerful get elected.
And we are seeing the results of how oligarchy functions right now in Congress where the Republican leadership wants to throw 23 million American off of health insurance, cut Medicaid by over $800 billion, defund Planned Parenthood, cut food stamps and other nutrition programs by over $200 billion, cut Head Start and after school programs, and by the way, make drastic cuts in Pell grants and other programs that help working class kids be able to go to college.
And, unbelievably, at exactly the same time that they are throwing people off health care, making it harder to people to go to college, they have the chutzpah to provide the $300 billion in tax breaks to the top one percent. In other words, the very, very rich are getting richer and they get huge tax cuts. The working class and the middle class are struggling and they are seeing drastic cuts in life or death programs that could mean survival or not for those families.
Now, in response to these very serious crises it seems to me that we have two choices. First we can throw up our hands in despair. We can say, "I am not going to get involved."
That is understandable. But it is wrong.
Because the issues that we deal with today—the economic issues, the social issues, the racial issues, the environmental issues—not only impact your lives, they impact the lives of future generations and you do not have the moral right to turn your back on saving this planet and saving future generations.
The truth is that the only rational choice we have, the only real response we can make is to stand up and fight back — reclaim American democracy and create a government that works for all of us, not just the one percent.
And for us to do that it is necessary that we fight for a vision of a new America. An America based on progressive, humane values, not the values of the oligarchy.
And what does that mean, briefly in concrete terms?
It means that, no, we are not going to throw 23 million Americans off the health care they have. We are going to bring about health care for all as a right, not a privilege.
It means that, no, we are not, as the current administration does, deny the reality of climate change. We are going to take on the fossil fuel industry, transform our energy system away from fossil fuels to energy efficiency and sustainable energy.
It means no we are not going to cut Pell grants and other student assistance. We are going to do what Germany, what Scandinavia, what countries all over the world do. And that is to make certain the public colleges and universities are tuition-free and we're going to significantly lower student debt because we believe that anyone in America who has the ability and the desire to be able to get a higher education regardless of his or her income.
And no we're not going to do what the attorney general of the United States now wants. We're not going to put more people in jail. We're going to fix a broken criminal justice system and invest in education and jobs for our young people, not more jails and incarceration.
No, we're not going to defund Planned Parenthood. We're going to vigorously defend a woman's right to choose.
My friends, let me conclude by saying this. We live in the wealthiest country in the history of the world. We are seeing exploding technology, which if used well, has extraordinary potential to improve life. We are an intelligent and hardworking people. If we are prepared to stand together; if we take on greed and selfishness; if we refuse to allow demagogues to divide us up there is no end to what the great people of our nation can accomplish.
So today as you graduate Brooklyn College, my message to you is very simple. Think big, not small, and help us create the nation that we all know we can become. Thank you all very much.

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>
The U.S. reported more than 55,000 new coronavirus cases on Thursday, in a sign that the outbreak is not letting up as the Fourth of July weekend kicks off.

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>

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>

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.

Billions worth of valuable metals such as gold, silver and copper were dumped or burned last year as electronic waste produced globally jumped to a record 53.6 million tons (Mt), or 7.3 kilogram per person, a UN report showed on Thursday.
Environmental and Health Hazard<p>Experts say e-waste, which is now the world's fastest-growing domestic waste stream, poses serious environmental and health risks.</p><p>Simply throwing away electronic items without ensuring they get properly recycled leads to the loss of key materials such as iron, copper and gold, which can otherwise be recovered and used as primary raw materials to make new equipment, thereby reducing greenhouse gas emissions from extraction and refinement of raw materials.</p><p>Refrigerants found in electronic equipment such as fridge and air conditioners also contribute to global warming. A total of 98 Mt of CO2-equivalents, or about 0.3% of global energy-related emissions, were released into the atmosphere in 2019 from discarded refrigerators and ACs that were not recycled properly, the report said.</p><p>E-waste contains several toxic additives or hazardous substances, such as mercury and brominated flame retardants (BFR), and simply burning it or throwing it away could lead to serious health issues. Several studies have linked unregulated recycling of e-waste to adverse birth outcomes like stillbirth and premature birth, damages to the human brain or nervous system and in some cases hearing loss and heart troubles.</p><p>"Informal and improper e-waste recycling is a major emerging hazard silently affecting our health and that of future generations. One in four children are dying from avoidable environmental exposures," said Maria Neira, director of the Environment, Climate Change and Health Department at the World Health Organization. "One in four children could be saved, if we take action to protect their health and ensure a safe environment."</p>
Europe Leads the Way<p>While most of the e-waste was generated in Asia (24.9 Mt) in 2019, Europe led the charts on a per person basis with 16.2 kg per capita, the report said.</p><p>But the continent also recorded the <a href="https://www.dw.com/en/the-eu-declares-war-on-e-waste/a-51108790" target="_blank">highest documented formal e-waste collection and recycling</a> rate at 42.5%, still below its target of 65%. Europe was well ahead of the others on this front. Asia ranked second with 11.7%.</p><p>The authors said while more that 70% of the world's population was covered by some form of e-waste policy or laws, not much was being done toward implementation and enforcement of the regulations to encourage the take-up of a collection and recycling infrastructure due to lack of investment and political motivation.</p><p>"You have to think about new economic systems," said Kühr.</p><p>One approach could be that consumers no longer buy the products, but only the service they offer. The device would remain the property of the maker, who would then have an interest in offering his customers the best service and the necessary equipment. The maker would also be interested in designing his products in such a way that they are easier to repair and easier to recycle, Kühr said.</p>
