22 April is Earth Day. While the coronavirus (COVID-19) has been spreading around the world and dominating news headlines, thoughts, and attention, the need to take climate action has remained as urgent as ever. Earth Day is not just the 50th anniversary of Earth Day, but also the anniversary of the signing of the Paris Agreement to take climate action. The pandemic is a stark reminder of the vulnerability of humans and the planet in the face of global-scale threats. Unchecked damage to our environment must be addressed, as we see more of these viruses now we need to understand why they are showing up. So a little history about Earth Day. The first Earth Day took place in 1970. Outraged by oil spills, smog, and polluted rivers, 20 million people took to the streets, protesting what they recognized as an environmental crisis. It was the planet’s largest civic event at the time and compelled governments to take concrete actions, including passing environmental laws and establishing environmental protection agencies. In addition to these practical outcomes, the event demonstrated just how much can be achieved when people come together and demand action.
