Cute Earth Day Wallpapers

This was the first year that Earth Day used the Internet as its principal organizing tool, and it proved invaluable nationally and internationally.

The event ultimately enlisted more than 5,000 environmental groups outside the United States, reaching hundreds of millions of people in a record 183 countries.

The April 22 Earth Day in 2000 combined the big-picture feistiness of the first Earth Day with the international grassroots activism of Earth Day 1990.

For 2000, Earth Day had the internet to help link activists around the world.
