BIODIVERSITY

Big progress begins with small acts.

In 1970, 20 million Americans took to the streets on the first Earth Day. That collective action helped propel the Clean Air Act, the Clean Water Act and the Endangered Species Act — fundamentally reshaping the nation’s relationship with the natural world. It's hard to imagine what the United States might look like without them.

Today, that legacy is global.

The same force that drove the first Earth Day is still what moves conservation forward today. Around the world, scientists, Indigenous leaders and local communities are pressing seedlings into mud, changing the way they farm and training the next generation to carry the work forward. In Madagascar, they're keeping rice fields from being buried by sediment. In Colombia, they're helping mountains hold water again. In Timor-Leste, they're reading the reefs and acting on what they find.

It is persistent, human-powered work. This Earth Day, we’re sharing a few of those stories.
