How did the coronavirus affect what you plan to focus on this year? It has squashed the big public events, but you were planning to focus on the climate crisis. Is the respite from cars and commerce all over the world—the cleaner air, lack of fossil fuels spewing through town and country during the lockdown—now a part of the Earth Day message?

For Earth Day 2020—the 50th anniversary of Earth Day—the coronavirus proved to be the ultimate Black Swan. For more than two years, a large team of talented people have been organizing around the planet to produce huge crowd events demanding bold action on climate. Essentially, a global Green New Deal. 

Events were planned in more than 180 nations—some of them enormous. In the United States, I was hoping for 750,000 people on the National Mall. Internationally, building on the work of the student climate strikers, 350.org, and Extinction Rebellion, as well as all the major environmental groups; colleges & universities; K-12 schools around the world; museums, zoos, aquariums, and botanical gardens; religions (Pope Francis had pledged a very major service on Earth Day in St. Peter’s Square); social justice groups; indigenous groups, public health groups; and others, I had hoped to have 1 billion people in the streets on April 22—many with diverse specific goals but all with a shared belief that, after decades of reports, conferences and official indecisiveness, we have run out of time to dawdle.  

COVID-19 came roaring out of a wet market in Wuhan and overnight spread to the world.  Essentially everything that we had spent two years organizing around the entire planet became impermissible—actually became illegal—in a couple of weeks.

What does this mean for Earth Day 2020?

At a personal level, it is devastating. I gave my first global warming speech—a keynote to the AAAS—in January 1980.  I never dreamed we’d have made no global progress reducing greenhouse gases in 40 years. I dreamed of Earth Day 2020 as the climate inflection point where mankind began producing less and less greenhouse gas emissions every future year.  I’ve been involved with Earth Day for 50 years now, and this 50th anniversary was when we were to bring it all home—doing for the planet what the first Earth Day did for America—successfully demanding swift, bold action. 

How does the Earth Day Network plan to save the day? 

The Earth Day Network staff is working its collective tail off trying to stitch together a significant online stream event that is interesting and educational and inclusive.  But in terms of political impact, there is simply no substitute for a billion people in the streets—and right now, that is against the law.  

Looking for positives…seeds, as you know, are a hot commodity these days. Do you think the pandemic, because of the clearer air and slowed down pace of life we’re experiencing, will lead to greener habits? Or do you think people will revert to how they have always behaved once the coronavirus crisis has abated?

The biggest impact of Covid-19 on behavior is almost certainly the shift to working at home by those lucky enough to have jobs that can be done at home. One indicator of the business shift is that three months ago, Zoom averaged 10 million calls a day; today it has scaled to 200 million calls per day. This saves all the fuel used for traveling to the office and all the pollution from its combustion. People who ordinarily have long, aggravating commutes or have to change buses two or three times to get to work are finding better ways to use those hours. They are able to spend time with their families (albeit not with their neighbors.)  

Don’t you think this will change once the pandemic is squashed?

If everyone in the company worked one day a week from home, the group could reduce the size of it’s office space by one-fifth (which eventually could reduce office energy costs for HVAC, etc.)

What other pandemic-forced changes in everyday life could lead to lasting benefits for the planet?

Besides seeds, the big shift in food is cooking at home, as so very many of the nation’s restaurants have closed. Cooking your own food is much cheaper, for starters, because you are doing work you used to pay chefs and waiters to do, and you can absolutely control the quality of the ingredients and the size of the portions. In theory, there should be much less wastage because you can stick leftovers right in the refrigerator. And the increased demand for seeds and starter plants suggests that people will grow more of their own food, reducing the energy costs of transporting and processing food—and assuring that it is genuinely organic. Also, since people are not buying cows and pigs, they may be shifting lower on the food chain—which is healthier for them and better for the environment. 

What about our social lives?

Movie theaters have essentially stopped operating, and Netflix, Hulu, Amazon, et al. are thriving. Again, that saves on transportation, valuable land being paved for parking lots, and in all times significantly lowering the chances of catching a cold or other minor disease from someone else in the theater. It will be interesting to see whether this will carry over permanently to competitive athletics. Some people love the group experience of joining 80,000 fellow fans in a stadium, though I’ve always preferred to watch at home (better views; informed commentary; greater comfort; no driving/parking, and vastly less expensive) but I expect that change will not prove permanent.  

The most important potential impact, if I allow myself to be optimistic, may not be behavioral but attitudinal. Covid-19 has no respect for borders, and in our globalized world every nation gains a benefit from keeping other nations safe. There is some degree of deference to medical expertise and to the World Health Organization—which has authority but no power.  Similarly, many of the most important environmental issues are similarly global, or transcend national borders. No nation can solve global warming by itself, or prevent migratory species from going extinct when some other nation destroys crucial habitat, or protect deep ocean fisheries or ocean acidification. If Covid-19 helps us understand that we need to confront some things as Homo sapiens, not as Americans, Turks, Chinese, Filipinos, Indians, Saudis or other hyper-nationalist politics, that would be a huge benefit.

No one expected a disease to usurp the urgency of the most urgent crisis of our time. 

In the environmental arena, it is the latest and perhaps the scariest zoonotic disease to emerge. These tend to bear some relationship to a growing human population with a desire for greater prosperity encroaching on natural habitats, driving wild animals into smaller and smaller areas. (If you put all the human on the planet on one side of a scale and all the terrestrial wild vertebrates—the elephants and tigers and deer and bears and wolves and elk and zebra and wildebeests and everything else on the other side, humans would outweigh everything else by a ratio of two to one. If you put all our domesticated animals—cows, pigs, chickens, pets—with us on the scale, we would outweigh everything else by a ratio of eight to one.) 

These zoonotic diseases that can be transmitted not just from animals to people but from people to animals, and among animals and among people, to which we have developed no immunity, are a real threat. And they offer a pretty strong argument to leave more natural areas free from human cultivation and development.
