The first Earth Day on April 22, 1970, activated 20 million Americans and is widely credited with launching the modern environmental movement. It remains the largest civic engagement event in human history. Led by Earth Day Network, more than 1 billion people in over 190 countries take action on Earth Day, making it the world's largest civic event.
We work year round on solutions that address environmental challenges from mitigating and adapting to climate change and global warming, to ending plastic pollution and protecting endangered species. We work to broaden and diversify the environmental movement by mobilizing people, communities, businesses and elected leaders across the globe. We address environmental issues that affect us all, including those that impact human health. We are leaders in environmental education and environmental advocacy.
As Earth Day moves towards its 50th anniversary in 2020, we are working harder than ever to expand the environmental movement and inspire the next generation of optimistic and engaged leaders, to move us towards a healthy sustainable future.
