Fighting Climate Change Isn’t Just an Environmental Issue — it’s a Social Justice Issue Too
By Emily Dao
We constantly hear the narrative that climate change impacts us all. And while that's true, the issue is disproportionately impacting people of color, especially Black, Latino, and Native Americans. And when it comes to environmental justice, we just aren't talking about social equity enough.
A decade ago, Grist reporter Alan Durning wrote on the topic of climate change and race, "It's 2010. Some things have changed; others have not. Racial discrimination has diminished but persists, often in hidden and even subconscious ways."
Even now, seemingly hidden barriers continue to burden marginalized communities with the effects of climate change.
So, even well-intentioned plans to adopt new eco-friendly practices could severely hurt vulnerable groups. The plea for environmental justice deals with ensuring basic human rights. This includes access to clean water, clean air, power, and shelter.
Flint Serves as One of the Most Popular Instances of Denied Environmental Justice.
Perhaps your first time being exposed to environmental racism was when you learned about Flint, Michigan. In fact, University of Michigan researcher Paul Mohai called it "the most egregious example of environmental injustice in recent U.S. history."
When residents complained about contaminated water supply, state officials quickly and publicly dismissed citizens' claims. Residents almost immediately noticed a change in their water supply back in April 2014. Flint is a city of nearly 100,000 people. But, the state waited over a year to address the issue, finally doing so in October 2015…a full eighteen months.
Let's look at some numbers. Black Americans made up only 14% of Michigan. However, the most heavily polluted zip code in Michigan is 84% Black. For Flint and their Republican-controlled state government, NYT report John Eligon said it meant the city had "little political power."
A state report by the Michigan Civil Rights Commission verified that racism was a contributing factor in the water crisis. Government inaction led to a major Legionnaire's outbreak from the poisoned water. This disease is a severe form of bacterial pneumonia. Michigan reported at least 90 citizens were sickened and 12 died. However, a PBS FRONTLINE investigation found that 115 people actually died in Flint.
In January, over 30,000 Flint residents have filed lawsuits against city and state regulators for reparations. But, NPR says it's "unclear" if anyone will ever face trial for this injustice.
"The people in Flint, in terms of justice, holding people accountable and compensation…we are batting zero," Flint resident Claire McClinton told NPR.
So, it's no surprise that people often refer to Flint when it comes to environmental racism.
Lacking Social Equity: Underserved Communities Experience More Exposure to Dangerous Air.
Overwhelmingly, Latino and Black Americans live closer to toxic waste facilities, coal plants, or other areas not compliant with federal air pollution regulations. These instances, in turn, are associated with significant respiratory problems among these marginalized groups.
An analysis in California from the Union of Concerned Scientists affirmed this idea. In the study, they found that U.S., Black, Latino, Asian, and low-income communities suffered the most from poor air quality — and impacted Black Americans the most.
They experience 43% more exposure to PM2.5 pollution than White Californians. (Fine particulates from PM2.5 pollution are smaller in width than human air and form from diesel exhaust, smokestacks, construction projects, etc. Exposure to PM2.5 pollution is actually the 6th leading cause of death in the world.) And you'd think that more would be done to fix this as a respiratory virus, COVID-19 ravaged the world. Instead, the EPA stopped enforcing air pollution rules during the virus. This, among other reasons, explains why people of color are at higher risk of contracting COVID-19.
Tragically, those hit hardest by pollution contribute the least. The same study found that California households without a personal vehicle were actually exposed to higher levels of air pollution. This is because these households are usually in urban areas, which are typically surrounded by heavy traffic.
Those living in low-income households already are at increased risk of a lower life expectancy. They're also more likely to contract chronic conditions like heart disease and diabetes. So, for poor communities, living near polluting facilities only makes them more vulnerable to dangerous health effects.
Low-Income Households, People of Color Are Left in the Dark.
The transition to renewable energy revealed a lack of equity for the poor and people of color. (Minority groups often overrepresent impoverished neighborhoods. A study by the U.S. Department of Health and Human Services found that 40% of Americans living in poverty are black. Take in mind, Black Americans make up less than 20% of the U.S. population).
840 million people in the world still suffering from energy poverty. Overwhelmingly in the U.S., those struggling to pay for rising energy costs tend to be low-income Black and Latino Americans.
Given that many underserved communities don't even have reliable power, it makes sense that they're also less likely to have access to clean or energy-efficient technologies.
Time and Time Again, Research Reveals Inequity in Clean Energy.
University of Michigan Professor, Tony Reames found financial inequity in clean energy. His study revealed that upgrading to energy-efficient lightbulbs cost twice the amount in low-income neighborhoods compared to more affluent areas. And, for every dollar, Michigan spent on energy efficiency programs for low-income customers? The state spent $4.34 on high-income customers.
Additionally, in New Orleans, Grist reported that 20% of residents' income went to their energy bills. It's no wonder that the city, which has one of the nation's highest poverty rates, is also one of the least energy-efficient in the U.S.
And unfortunately, extreme rising temperatures due to climate change will only continue threatening power grids. This will result in heightened cases of blackouts. California's series of wildfires last year also hurt low-income households the most.
Last year, the California Department of Social Services reported that almost 51,000 households relying on food assistance lived in areas heavily impacted by planned outages to mitigate wildfires. For some, blackouts can definitely be an inconvenience. But, they can be devastating — and even deadly — to the poor and elderly.
Natural Disasters Disproportionately Impact Poorer Communities.
Natural disasters caused over $80 billion in damages in 2019. While disasters don't discriminate which areas they affect, recovery is much harder for the poor.
In times of despair, people tend to rally together. However, there's not an even dispersion of aid and attention. The Atlantic pointed out that private and public aid often "accrue to the haves more so than the have nots."
Brad Kieserman, VP of Disaster Logistics and Operations at the American Red Cross, discussed this after the Camp Fire wildfire.
"Disasters, for most communities, exacerbate already existing issues, which is why we often see in shelters what we sometimes refer to as the least, the last, and the lost'," he told the Atlantic. "The people who had the least, who were the last to get services, who were already at the end, who were lost beforehand, especially financially."
Environmental Justice a Big Challenge for the Native American Community.
According to The Conversation, 90 years of data show poverty rates climbing by 1% after natural disasters, impacting the poor most. For them, resiliency after devastations might not be possible.
"Our research suggests that the rich may have the resources to move away from areas facing natural disasters, leaving behind a population that is disproportionately poor," it wrote.
Then, when applying for recovery aid, Native Americans struggle most. Extreme heat and droughts harm plants and wildlife. They also create higher risks of wildfires and habitat loss. Since Native Americans depend heavily on natural resources, plants, and animals, it makes them vulnerable to climate change.
Yet, the National Congress of American Indians revealed that tribal citizens only received $3 on average for recovery efforts. Conversely, U.S. citizens received $26. Nelson Andrews Jr., Emergency Management Director for Mashpee Wampanoag Tribe discussed this with High Country News.
"It's basically like you're [Congress] setting us up to fail," he said.
The Importance of Your Vote in Achieving Environmental Justice.
After the Green New Deal was introduced back in 2019, AOC's sweeping proposal helped put climate policy on the map. One reason this outline got so much traction was that it heavily confronted social issues. This emphasis on social justice proved its important role in the climate narrative.
Although the Green New Deal did receive significant backlash over its feasibility, it did reinforce the idea that social justice and climate cannot exist as separate battles. In order for us to make significant progress in the fight against climate change, everyone must reap the benefits of a cleaner world.
The environment is the third most important issue in swing states. However, just focusing on the environment is not enough. When creating these solutions, poor, vulnerable communities must also be taken into consideration. We must demand environmental justice to enact real change.
Now more than ever is the time to use your voice, get loud, and stand up for what you believe is right. Now is the time to vote for our future.

Climate Explained is a collaboration between The Conversation, Stuff and the New Zealand Science Media Centre to answer your questions about climate change.
If you have a question you'd like an expert to answer, please send it to firstname.lastname@example.org
What was the climate and sea level like at times in Earth’s history when carbon dioxide in the atmosphere was at 400ppm?<p>The last time global carbon dioxide levels were consistently at or above 400 parts per million (ppm) was around <a href="https://www.nature.com/articles/nature14145" target="_blank">four million years ago</a> during a geological period known as the <a href="http://www.geologypage.com/2014/05/pliocene-epoch.html" target="_blank">Pliocene Era</a> (between 5.3 million and 2.6 million years ago). The world was about 3℃ warmer and sea levels were higher than today.</p><p>We know how much carbon dioxide the atmosphere contained in the past by studying ice cores from Greenland and Antarctica. As compacted snow gradually changes to ice, it traps air in bubbles that contain <a href="https://www.cambridge.org/core/journals/annals-of-glaciology/article/enclosure-of-air-during-metamorphosis-of-dry-firn-to-ice/09D9C60A8DA412D16645E6E6ABC1892F" target="_blank">samples of the atmosphere at the time</a>. We can sample ice cores to reconstruct past concentrations of carbon dioxide, but this record only takes us back about a million years.</p><p>Beyond a million years, we don't have any direct measurements of the composition of ancient atmospheres, but we can use several methods to estimate past levels of carbon dioxide. One method uses the relationship between plant pores, known as stomata, that regulate gas exchange in and out of the plant. The density of these stomata is <a href="https://journals.sagepub.com/doi/abs/10.1177/095968369200200109" target="_blank">related to atmospheric carbon dioxide</a>, and fossil plants are a good indicator of concentrations in the past.</p><p>Another technique is to examine sediment cores from the ocean floor. The sediments build up year after year as the bodies and shells of dead plankton and other organisms rain down on the seafloor. We can use isotopes (chemically identical atoms that differ only in atomic weight) of boron taken from the shells of the dead plankton to reconstruct changes in the acidity of seawater. From this we can work out the level of carbon dioxide in the ocean.</p><p>The data from four-million-year-old sediments suggest that <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2010PA002055" target="_blank">carbon dioxide was at 400ppm back then</a>.</p>
Sea Levels and Changes in Antarctica<p>During colder periods in Earth's history, ice caps and glaciers grow and sea levels drop. In the recent geological past, during the most recent ice age about 20,000 years ago, sea levels were at least <a href="https://science.sciencemag.org/content/292/5517/679.abstract" target="_blank">120 meters lower</a> than they are today.</p><p><span></span>Sea-level changes are calculated from changes in isotopes of oxygen in the shells of marine organisms. For the Pliocene Era, <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2004PA001071" target="_blank">research</a> shows the sea-level change between cooler and warmer periods was around 30-40 meters and sea level was higher than today. Also during the Pliocene, we know the West Antarctic Ice Sheet was <a href="https://www.nature.com/articles/nature07867" target="_blank">significantly smaller</a> and global average temperatures were about 3℃ warmer than today. Summer temperatures in high northern latitudes were up to 14℃ warmer.</p><p>This may seem like a lot but modern observations show strong <a href="https://journals.ametsoc.org/jcli/article/23/14/3888/32547" target="_blank">polar amplification</a> of warming: a 1℃ increase at the equator may raise temperatures at the poles by 6-7℃. It is one of the reasons why Arctic sea ice is disappearing.</p>
Impacts in New Zealand and Australia<p>In the Australian region, there was no Great Barrier Reef, but there may have been <a href="https://link.springer.com/content/pdf/10.1007/BF02537376.pdf" target="_blank">smaller reefs along the northeast coast of Australia</a>. For New Zealand, the partial melting of the West Antarctic Ice Sheet is probably the most critical point.</p><p>One of the key features of New Zealand's current climate is that Antarctica is cut off from global circulation during the winter because of the big <a href="https://www.tandfonline.com/doi/abs/10.3402/tellusa.v54i5.12161" target="_blank">temperature contrast</a> between Antarctica and the Southern Ocean. When it comes back into circulation in springtime, New Zealand gets strong storms. Stormier winters and significantly warmer summers were likely in the mid-Pliocene because of a weaker polar vortex and a warmer Antarctica.</p><p>It will take more than a few years or decades of carbon dioxide concentrations at 400ppm to trigger a significant shrinking of the West Antarctic Ice Sheet. But recent studies show that <a href="http://nora.nerc.ac.uk/id/eprint/521027/" target="_blank">West Antarctica is already melting</a>.</p><p>Sea-level rise from a partial melting of West Antarctica could easily exceed a meter or more by 2100. In fact, if the whole of the West Antarctic melted it could <a href="http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.695.7239&rep=rep1&type=pdf" target="_blank">raise sea levels by about 3.5 meters</a>. Even smaller increases raise the risk of <a href="https://www.pce.parliament.nz/publications/preparing-new-zealand-for-rising-seas-certainty-and-uncertainty" target="_blank">flooding in low-lying cities</a> including Auckland, Christchurch and Wellington.</p>

Investment in U.S. offshore wind projects are set to hit $78 billion (€69 billion) this decade, in contrast with an estimated $82 billion for U.S. offshore oil and gasoline projects, Wood Mackenzie data shows. This would be a remarkable feat only four years after the first offshore wind plant — the 30 megawatt (MW) Block Island Wind Farm off the coast of Rhode Island — started operating in U.S. waters.
Corporates Shift<p>Helping to drive offshore growth, U.S. corporate buyers <a href="https://www.dw.com/en/cities-leading-the-transition-to-renewables/a-42850621" target="_blank">are increasingly relying on wind energy to power their businesses</a>. Walmart and AT&T are the two top corporate wind buyers, while 14 newcomers entered the wind market in 2019, including Estée Lauder and McDonald's.</p><p>"Oil and gas companies have jumped into the U.S. offshore wind market, where they can transfer expertise in offshore fossil fuel development to clean energy investments," says Max Cohen, principal analyst, Americas Power & Renewable research at Wood Mackenzie. Many international oil and gas companies have already recognized this huge potential and entered the US offshore wind market, including Orsted, Equinor and Shell.</p><p>"Given the recent tumult in oil prices, fossil fuel companies may more and more be looking to diversify their portfolios, particularly with assets that are contracted or offer returns uncorrelated with oil and gas," Cohen says. "Offshore wind is an area where they may have a comparative advantage, and they can then leverage the experience with that technology to make the leap to onshore wind, solar, and other renewable technologies," he says.</p>
East Coast leads the way<p>"There is enormous opportunity, especially off the East Coast, for wind. I am very bullish," said former Interior Secretary Ryan Zinke. "Market excitement is moving towards offshore wind. I haven't seen this kind of enthusiasm from industry since the Bakken shale boom," he said.</p><p>Offshore wind initiatives require excessive upfront spending: a 250 MW venture costs about $1 billion, based on International Energy Agency data, but as costs fall the tipping point after which costs fall faster gets nearer</p><p>"The opportunity has been created by Northeastern states seeing the large price declines for offshore wind in Europe," says Cohen. Onshore wind is historically the lowest cost renewable resource, but is at its most expensive in the Northeast, he adds. "But costs are falling slower than for other technologies," he says.</p>
Jobs and Coastal Revitalization<p>U.S. wind energy now supports 120,000 US jobs and 530 domestic factories. A study by the University of Delaware predicted that the supply chain needed to build offshore turbines to feed power to seven East Coast states by 2030 would generate nearly $70 billion in economic activity and at least 40,000 full-time jobs. An American Wind Energy Association's (AWEA's) March 2020 report estimated that developing 30,000 MW of offshore wind along the East Coast could support up to 83,000 jobs and $25 billion in annual economic output by 2030.</p><p>Having said that, not all of the jobs are American jobs. The offshore wind developers with commercial leases in the US are all foreign companies. There is growing interest from the shipbuilding sector in the Gulf of Mexico in partnering with offshore wind companies to provide services. As a result, some of the US oil trade associations have submitted comments supporting certain aspects of offshore wind. "However, it is unclear to what extent offshore wind developers plan to use US vessels and crew, and the existing projects did not incorporate US vessels or labor at all," Hawkins says.</p>

The COVID-19 pandemic has revealed both the strengths and limitations of globalization. The crisis has made people aware of how industrialized food production can be, and just how far food can travel to get to the local supermarket. There are many benefits to this system, including low prices for consumers and larger, even global, markets for producers. But there are also costs — to the environment, workers, small farmers and to a region or individual nation's food security.

The human body comprises around 60% water.
It's commonly recommended that you drink eight 8-ounce (237-mL) glasses of water per day (the 8×8 rule).
1. Helps Maximize Physical Performance<p>If you don't stay hydrated, your physical performance can suffer.</p><p>This is particularly important during intense exercise or high heat.</p><p>Dehydration can have <a href="https://www.healthline.com/health/how-to-tell-if-youre-dehydrated" target="_blank">a noticeable effect</a> if you lose as little as 2% of your body's water content. However, it isn't uncommon for athletes to lose as much as 6–10% of their water weight via sweat.</p><p>This can lead to altered body temperature control, reduced motivation, and increased fatigue. It can also make exercise feel much more difficult, both physically and mentally.</p><p>Optimal hydration has been shown to prevent this from happening, and it may even reduce the <a href="https://www.healthline.com/health/oxidative-stress" target="_blank">oxidative stress</a> that occurs during high intensity exercise. This isn't surprising when you consider that muscle is about 80% water.<a href="https://pubmed.ncbi.nlm.nih.gov/19344695" target="_blank"><span></span></a></p><p>If you exercise intensely and tend to sweat, staying hydrated can help you perform at your absolute best.</p><p><strong>Summary</strong></p><p><strong></strong>Losing as little as 2% of your body's water content can significantly impair your physical performance.</p>
2. Significantly Affects Energy Levels and Brain Function<p>Your brain is strongly influenced by your hydration status.</p><p>Studies show that even mild dehydration, such as the loss of 1–3% of body weight, can impair many aspects of brain function.</p><p>In a study in young women, researchers found that fluid loss of 1.4% after exercise impaired both mood and concentration. It also increased the frequency of headaches.</p><p>Many members of this same research team conducted a similar study in young men. They found that fluid loss of 1.6% was detrimental to working memory and increased feelings of anxiety and fatigue.<a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/mild-dehydration-impairs-cognitive-performance-and-mood-of-men/3388AB36B8DF73E844C9AD19271A75BF/core-reader" target="_blank"></a></p><p>A fluid loss of 1–3% equals about 1.5–4.5 pounds (0.5–2 kg) of body weight loss for a person weighing 150 pounds (68 kg). This can easily occur through normal daily activities, let alone during exercise or high heat.</p><p>Many other studies, with subjects ranging from <a href="https://www.healthline.com/health/parenting/signs-of-dehydration-in-toddlers" target="_blank">children</a> to <a href="https://www.healthline.com/health/symptoms-of-dehydration-in-elderly" target="_blank">older adults</a>, have shown that mild dehydration can impair mood, memory, and brain performance.</p><p><strong>Summary</strong></p><p><strong></strong>Mild dehydration (fluid loss of 1–3%) can impair energy levels, impair mood, and lead to major reductions in memory and brain performance.</p>
3. May Help Prevent and Treat Headaches<p>Dehydration can trigger <a href="https://www.healthline.com/health/dehydration-headache" target="_blank">headaches</a> and migraine in some individuals.<span></span></p><p>Research has shown that a headache is one of the most common symptoms of dehydration. For example, a study in 393 people found that 40% of the participants experienced a headache as a result of dehydration.</p><p>What's more, some studies have shown that drinking water can help relieve headaches in those who experience frequent headaches.</p><p>A study in 102 men found that drinking an additional 50.7 ounces (1.5 liters) of water per day resulted in significant improvements on the Migraine-Specific Quality of Life scale, a scoring system for <a href="https://www.healthline.com/health/migraine-symptoms" target="_blank">migraine symptoms</a>.<a href="https://academic.oup.com/fampra/article/29/4/370/492787" target="_blank"></a></p><p>Plus, 47% of the men who drank more water reported headache improvement, while only 25% of the men in the control group reported this effect.<a href="https://academic.oup.com/fampra/article/29/4/370/492787" target="_blank"></a></p><p>However, not all studies agree, and researchers have concluded that because of the lack of high quality studies, more research is needed to confirm how increasing hydration may help improve headache symptoms and decrease headache frequency.<a href="https://pubmed.ncbi.nlm.nih.gov/26200171" target="_blank"></a></p><p><strong>Summary</strong></p><p><strong></strong>Drinking water may help reduce headaches and headache symptoms. However, more high quality research is needed to confirm this potential benefit.</p>
4. May Help Relieve Constipation<p><a href="https://www.healthline.com/health/constipation" target="_blank">Constipation</a> is a common problem that's characterized by infrequent bowel movements and difficulty passing stool.</p><p>Increasing fluid intake is often recommended as a part of the treatment protocol, and there's some evidence to back this up.</p><p>Low water consumption appears to be a risk factor for constipation in both younger and older individuals.</p><p>Increasing hydration may help decrease constipation.</p><p><a href="https://www.healthline.com/nutrition/mineral-water-benefits" target="_blank">Mineral water</a> may be a particularly beneficial beverage for those with constipation.</p><p>Studies have shown that mineral water that's rich in magnesium and sodium improves bowel movement frequency and consistency in people with constipation.<a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC5334415" target="_blank"></a></p><p><strong>Summary</strong></p><p><strong></strong>Drinking plenty of water may help prevent and relieve constipation, especially in people who generally don't drink enough water.</p>
5. May Help Treat Kidney Stones<p>Urinary stones are painful clumps of mineral crystal that form in the urinary system.</p><p>The most common form is <a href="https://www.healthline.com/health/kidney-stones" target="_blank">kidney stones</a>, which form in the kidneys.</p><p>There's limited evidence that water intake can help prevent recurrence in people who have previously gotten kidney stones.<a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD004292.pub3/full" target="_blank"></a></p><p>Higher fluid intake increases the volume of urine passing through the kidneys. This dilutes the concentration of minerals, so they're less likely to crystallize and form clumps.</p><p>Water may also help prevent the initial formation of stones, but studies are required to confirm this.</p><p><strong>Summary</strong></p><p><strong></strong>Increased water intake appears to decrease the risk of kidney stone formation.</p>
6. Helps Prevent Hangovers<p>A hangover refers to the unpleasant symptoms experienced after drinking <a href="https://www.healthline.com/nutrition/alcohol-good-or-bad" target="_blank">alcohol</a>.</p><p>Alcohol is a diuretic, so it makes you lose more water than you take in. This can lead to dehydration.</p><p>Although dehydration isn't the main cause of hangovers, it can cause symptoms like thirst, fatigue, headache, and dry mouth.</p><p>Good ways <a href="https://www.healthline.com/nutrition/7-ways-to-prevent-a-hangover" target="_blank">to reduce hangovers</a> are to drink a glass of water between drinks and have at least one big glass of water before going to bed.</p><p><strong>Summary</strong></p><p><strong></strong>Hangovers are partly caused by dehydration, and drinking water can help reduce some of the main symptoms of hangovers.</p>
7. Can Aid Weight Loss<p>Drinking plenty of water can help you <a href="https://www.healthline.com/nutrition/how-to-lose-weight-as-fast-as-possible/" target="_blank">lose weight</a>.</p><p>This is because water can increase satiety and boost your metabolic rate.</p><p>Some evidence suggests that increasing water intake can promote weight loss by slightly increasing your metabolism, which can increase the number of calories you burn on a daily basis.</p><p>A 2013 study in 50 young women with overweight demonstrated that drinking an additional 16.9 ounces (500 mL) of water 3 times per day before meals for 8 weeks led to significant reductions in body weight and body fat compared with their pre-study measurements.</p><p>The timing is important too. Drinking water half an hour before meals is the most effective. It can make you feel more full so that you <a href="https://www.healthline.com/nutrition/35-ways-to-cut-calories" target="_blank">eat fewer calories</a>.</p><p>In one study, dieters who drank 16.9 ounces (0.5 liters) of water before meals lost 44% more weight over a period of 12 weeks than dieters who didn't drink water before meals.</p>
The Bottom Line<p>Even mild dehydration can affect you mentally and physically.</p><p>Make sure that you <a href="https://www.healthline.com/nutrition/how-much-water-should-you-drink-per-day" target="_blank">get enough water each day</a>, whether your personal goal is 64 ounces (1.9 liters) or a different amount. It's one of the best things you can do for your overall health.</p>

The enduring pandemic will make conventional forms of travel difficult if not impossible this summer. As a result, many will consider virtual alternatives for their vacations, including one of the oldest forms of virtual reality – books.
