For youth climate activists, Earth Day 2020 was going to be epic. Fueled by the global climate strikes that drew millions of young people into streets around the world in 2019, the holiday's historic 50th anniversary held the promise of unprecedented participation and enthusiasm.
Then the pandemic hit. When the ability to hold large gatherings came to a screeching halt in March, just a handful of weeks before Earth Day, events and marches were cancelled. Activists rallied as best they could and managed to pull off an impressive three-day livestream event online, but like everything we've experienced since COVID-19 arrived, it wasn't the same.
Add on climate-focused candidate Bernie Sanders dropping out of the U.S. presidential race in April, and the spring of 2020 was a tough time for youth climate activists. "We just really felt like there was this energy sucked out of the movement," says Katie Eder, 19-year-old founder and Executive Director of Future Coalition. "And there was a lot of cynicism around the election."
Isha Clarke, 17-year-old cofounder of Oakland's Youth vs. Apocalypse, says she was "upset" and "depressed" the following month in the wake of George Floyd's murder. "It was like, I'm already here, stuck inside because of COVID," she recalls, "which is already disproportionately killing Black people and Indigenous people. And it's putting people out of work and making frontline communities even more vulnerable. And I'm missing my senior year, and everything is just crazy—and then this."
Clarke started doing some organizing around Black Lives Matter, which led her to consider the weight of this moment. "I was thinking about strategy and tactics, and I was thinking 'What is going to make this a pivotal moment in history, rather than just a memorable one?' And I think what is going to make this a pivotal moment is this real understanding and organizing around true intersectionality, on really finding the points on which our struggles intersect, and tear down this foundational system that is the root cause of all of these things."
Eder also says that the Black Lives Matter movement helped re-energize and re-focus the youth climate movement. "It sort returned this energy to young people that said, 'Okay, we don't need a presidential candidate to be the person driving this revolution. This is a people's revolution, and so that's what we need to do. So over the course of the summer we saw the climate movement showing up for the Black Lives movement in a big way, with that really being the priority."
Intersectionality—the idea that things like climate justice and racial justice and economic justice are not separate spheres, but rather interconnected issues that need to be tackled together—has become a dominating theme of the youth climate movement. In Clarke's opinion, white supremacy, patriarchy, colonialism, and capitalism have led us to the climate crisis, and progress on the climate front must include addressing those issues.
"We know that to fix the problem we're going to need as many young people in the streets, voting, and in legislative offices as possible, and so far we've been able to work with pretty much anyone and everyone when there's overlap."
"Climate justice has to be about working to dismantle these systems of oppression in every way that they exist, whether that be through environmental racism or police brutality or our faulty education system or detention centers, or whatever that is," says Clarke. "There are so many ways in which these foundational systems of oppression are harming people."
Eder concurs. "I think we've known this all along, but it's heightened this year, that when we talk about climate justice, we have to talk about racial justice and social justice. That needs to be the leading theme. It's not just about the polar bears and the ice caps—it's about people. That's a people's problem, and that's what we need to keep coming back to, finding the humanity in the crisis that otherwise feels really abstract."
Now, with the election just weeks away, activists are focusing much of their energies on getting out the vote.

Saad Amer is the 26-year-old founder of Plus1Vote, an organization launched prior to the 2018 midterm elections that encourages voter registration and participation by asking everyone to bring one person with them to the polls. Amer, who holds a degree in Environmental Science and Public Policy from Harvard, has been an environmental activist since he was 13 and has traveled the world exploring different ways people and communities are trying to battle climate change.
"What I found was that there were just consistent barriers to actually accomplishing anything with regard to climate action," says Amer. "And what so much of it comes down to is our elected officials." He founded Plus1Vote to mobilize young adults to get out and vote with the logic that "young people could fundamentally swing the election in a direction of climate champions."
Plus1Vote doesn't just advocate for climate policy, though. It also folds the issues of gun violence, health care, voting rights, and social justice in its campaigns. Like the other activists we spoke to, intersectionality is key to Amer's approach to change—and voting in supportive elected officials is key to facilitating all of it."Whether you're a racial justice organization, whether you're a climate-focused organization, women's rights, whatever it is, there's a clear common denominator in how we can take action on every single one of those fronts," says Amer. That common denominator is voting.

One quirk of youth activism is that many of the young people in the trenches aren't even old enough to vote themselves. Isha Clarke still has another year before she reaches voting age, but that isn't stopping her from pushing to get out the vote. In fact, her latest collaborative project is a campaign called "This is the Time," which launches in October and includes an action website where voting-age Americans can pledge to fight for the future and to vote for candidates who will too.
However, it would be a mistake to assume that all young climate change activists share the same political views—or even sit on the same side of the political aisle.
Benji Backer is a 22-year-old from Appleton, Wisconsin, who has been active in conservative politics since he was 10. Growing up in a family where "the environment was the number one value," Backer found himself frustrated with the political divide when it comes to the environment. So he decided to change it.
In 2017, he founded the American Conservative Coalition to make environmentalism bipartisan again, and to put forth market-based, limited-government ways to solve environmental challenges.
Backer says we need both sides at the table to solve the problem of climate change. He testified before Congress next to Greta Thunberg, and though they don't agree on everything, they shared the unified message that their generation was being left behind because of the unnecessary politicizing of climate change.
"Our generation doesn't look at the environment from a conservative vs. liberal angle," says Backer. "They look at it from an environmental angle. And to most young people, there's a deep frustration at the lack of action on a lot of issues, but most importantly climate change, because everyone knows it's a problem."
Backer believes that local, state, and federal governments have a role to play in solving climate change, but that role should be more about incentivising innovation in the marketplace than implementing hefty regulations. "The marketplace has spurred innovation and competition to create electric vehicles, to create better solar panels, to create wind energy," says Backer. "That's the marketplace doing it's thing." He points out that we don't have all the answers to solving climate change yet, and that we need to encourage innovation and technology in the marketplace to help us get there faster.
To show how companies are already playing a role in finding climate change solutions, Backer is currently on a 50-day tour of the country—in a Tesla—dubbed the "Electric Election Road Trip." His team is interviewing 40 companies, sharing their sustainability initiatives in a podcast, and compiling the experience into a documentary that will be released sometime next year.

Despite their different approaches to solutions, climate change activists across the political spectrum have found ways to work together. "We definitely collaborate on messaging," says Backer, "the importance of fighting climate change, the importance of youth action. And we know that to fix the problem we're going to need as many young people in the streets, voting, and in legislative offices as possible, and so far we've been able to work with pretty much anyone and everyone when there's overlap."
"And when there's not overlap," he adds, "we just go our separate ways for that specific issue."
There's no doubt that the pandemic and political upheaval we're all experiencing pose challenges to youth activists, but these young leaders are adjusting and charging ahead. The digital savvy they possess makes mobilizing and collaborating easier for them than for older generations, and they certainly aren't going to let a global virus outbreak stop them. The most striking thing about these young people is how their environmental knowledge, activism know-how, and ability to express themselves feels far beyond their years, without exception. While they're having to endure the uncertainty of the moment while navigating a pivotal stage of their own lives, these youth continue to provide a hopeful perspective and vision of the future—one that the world desperately needs.

Responding to COVID-19 outbreaks at more than 200 mink farms, the Danish government, in November 2020, culled its entire mink population. The Danish armed forces helped farmers slaughter each of their 17 million minks, which are normally farmed for their valuable fur.
The SARS-CoV-2 virus, said officials, spread from human handlers to the small, ferret-like animals, mutated, and then spread back to several hundred humans. Although the mass extermination faced much criticism, Denmark’s prime minister defended the decision last month, stating that the step was “necessary” and that the Danish government had “a responsibility for the health of the entire world.”
Over the past two and half years, COVID-19 infections have been reported in numerous animal species around the world. In addition to the Danish minks, there is other evidence that the virus can mutate as it’s transmitted back and forth between humans and animals, which increases the risk to public health. According to the World Health Organisation (WHO), COVID-19 vaccines for animals may protect the infected species and prevent the transmission of viral mutations. However, the development of such vaccines has been slow. Scientists attribute the deficiency to a lack of data.
“Several animal species have been predicted and found to be susceptible to SARS-CoV-2,” says Suresh V. Kuchipudi, interim director of the Animal Diagnostic Laboratory at the Huck Institutes of Life Sciences. But the risk remains unknown for many animals in several parts of the world, he says. “Therefore, there is an urgent need to monitor the SARS-CoV-2 exposure of high-risk animals in different parts of the world.”
In June, India introduced Ancovax, its first COVID-19 vaccine for animals. The development came a year after the nation reported that the virus had infected eight Asiatic lions, with two of them dying. While 30 COVID-19 vaccines for humans have been approved for general or emergency use across the world, Ancovax is only the third such vaccine for animals. The first, named Carnivac-Cov, was registered by Russia in March last year, followed by another vaccine four months later, developed by Zoetis, a U.S. pharmaceutical company.
Christina Lood, a Zoetis spokesperson, says the company has donated over 26,000 doses of its animal vaccine to over 200 zoos – in addition to 20 conservatories, sanctuaries and other animal organizations located in over a dozen countries, including Canada, Chile and the U.S. The vaccine, she adds, has been administered to more than 300 mammalian species so far.
“At least 75 percent of emerging infectious diseases have an animal origin, including COVID-19,” says Lood. “Now more than ever before, we can all see the important connection between animal health and human health."
The Dangers of COVID-19 Infections among Animals
Cases of the virus in animals have been reported in several countries across the world. As of March this year, 29 kinds of animals have been infected. These include pet animals like dogs, cats, ferrets and hamsters; farmed animals like minks; wild animals like the white-tailed deer, mule deer and black-tailed marmoset; and animals in zoos and sanctuaries, including hyenas, hippopotamuses and manatees. Despite the widespread infection, the U.S. Centres for Diseases Control and Prevention (CDC) has noted that “we don’t yet know all of the animals that can get infected,” adding that more studies and surveillance are needed to understand how the virus is spread between humans and animals.
Leyi Wang, a veterinary virologist at the Veterinary Diagnostic Laboratory, University of Illinois, says that captive and pet animals most often get infected by humans. It goes both ways, he says, citing a recent study in Hong Kong that found the virus spread from pet hamsters to people.
Wang’s bigger concern is the possibility that humans or domestic animals could transmit the virus back to wildlife, creating an uncontrollable reservoir of the disease, especially given the difficulty of vaccinating non-captive wild animals. Such spillbacks have happened previously with diseases such as plague, yellow-fever, and rabies.
It’s challenging and expensive to develop and implement animal vaccines, and demand has been lacking as the broader health risk for animals isn’t well known among the public. People tend to think only about their house pets.
In the past, other human respiratory viruses have proven fatal for endangered great apes like chimpanzees and gorillas. Fearing that COVID-19 could have the same effect, primatologists have been working to protect primates throughout the pandemic. Meanwhile, virus reservoirs have already been created among other animals, Wang says. “Deer of over 20 U.S. states were tested SARS-CoV-2 positive,” says Wang, pointing to a study that confirmed human-to-deer transmission as well as deer-to-deer transmission. It remains unclear how many wildlife species may be susceptible to the disease due to interaction with infected deer, says Wang.
In April, the CDC expressed concerns over new coronavirus variants mutating in wildlife, urging health authorities to monitor the spread of the contagion in animals as threats to humans. The WHO has made similar recommendations.
Challenges to Vaccine Development
Zoetis initiated development activities for its COVID-19 vaccine in February 2020 when the first known infection of a dog occurred in Hong Kong. The pharmaceutical giant completed the initial development work and studies on dogs and cats, and shared their findings at the World One Health Congress in the fall of 2020. A few months later, after a troop of eight gorillas contracted the virus at the San Diego Zoo Safari Park, Zoetis donated its experimental vaccine for emergency use in the great ape population.
Zoetis has uniquely formulated its COVID-19 vaccine for animals. It uses the same antigen as human vaccines, but it includes a different type of carrier protein for inducing a strong immune response. “The unique combination of antigen and carrier ensures safety and efficacy for the species in which a vaccine is used,” says Lood.
But it’s challenging and expensive to develop and implement animal vaccines, and demand has been lacking as the broader health risk for animals isn’t well known among the public. People tend to think only about their house pets. “As it became apparent that risk of severe disease for household pets such as cats and dogs was low, demand for those vaccines decreased before they became commercially available,” says William Karesh, executive vice-president for health and policy at EcoHealth Alliance. He adds that in affected commercial mink farms, the utility of a vaccine could justify the cost in some cases.
Although scientists have made tremendous advances in making vaccines for animals, Kuchipudi thinks that the need for COVID-19 vaccines for animals “must be evaluated based on many factors, including the susceptibility of the particular animal species, health implications, and cost.”.
Not every scientist feels the need for animal vaccines. Joel Baines, a professor of virology at Cornell University’s Baker Institute for Animal Health, says that while domestic cats are the most susceptible to COVID-19, they usually suffer mild infections. Big cats in zoos are vulnerable, but they can be isolated or distanced from humans. He says that mink farms are a relatively small industry and, by ensuring that human handlers are COVID negative, such outbreaks can be curtailed.
Baines also suggests that human vaccines could probably work in animals, as they were tested in animals during early clinical trials and induced immune responses. “However, these vaccines should be used in humans as a priority and it would be unethical to use a vaccine meant for humans to vaccinate an animal if vaccine doses are at all limiting,” he says.
William Karesh, president of the World Animal Health Organization Working Group on Wildlife Diseases, says the best way to protect animals is to reduce their exposure to infected people.
In the absence of enough vaccines, Karesh says that the best way to protect animals is the same as protecting unvaccinated humans - reduce their exposure to infected people by isolating them when necessary. “People working with or spending time with wild animals should follow available guidelines, which includes testing themselves and wearing PPE to avoid accidentally infecting wildlife,” he says.
The Link between Animal and Human Health
Although there is a need for animal vaccines in response to virus outbreaks, the best approach is to try to prevent the outbreaks in the first place, explains K. Srinath Reddy, president of the Public Health Foundation of India. He says that the incidence of zoonotic diseases has increased in the past six decades because human actions like increased deforestation, wildlife trade and animal meat consumption have opened an ecological window for disease transmission between humans and animals. Such actions chip away at the natural barriers between humans and forest-dwelling viruses, while building conveyor belts for the transmission of zoonotic diseases like COVID-19.
Many studies suggest that the source of COVID-19 was infected live animals sold at a wet market in China’s Wuhan. The market sold live dogs, rats, porcupines, badgers, hares, foxes, hedgehogs, marmots and Chinese muntjac (small deer) and, according to a study published in July, the virus was found on the market’s stalls, animal cages, carts and water drains.
This research strongly suggests that COVID-19 is a zoonotic disease, one that jumps from animals to humans due to our close relationship with them in agriculture, as companions and in the natural environment. Half of the infectious diseases that affect people come from animals, but the study of zoonotic diseases has been historically underfunded, even as they can reduce the likelihood and cost of future pandemics.
“We need to invest in vaccines,” says Reddy, “but that cannot be a substitute for an ecologically sensible approach to curtailing zoonotic diseases.”
