April 22, 2011 is the global celebration of Earth Day. Back in 1970, when Senator Nelson of Wisconsin first proposed Earth Day, it began as an environmental teach-in movement to be held at colleges and universities throughout the United States. Thousands of campuses organized environmental events and protests, which helped Earth Day become known as a day for environmental awareness. Today, Earth Day is celebrated in over 175 countries, with hundreds of thousands of environmental activists joining together in public spaces all across the globe to remind us that we must take care of our planet.
