Happy Earth Day! Let’s commemorate it with a view of some majestic Redwood trees in northern California. These coastal Redwoods are the tallest trees in the world.
Today is the 54th anniversary of the first Earth Day in 1970. It was founded on an idea proposed by Sen. Gaylord Nelson of Wisconsin. More than 20 million Americans that day participated in demonstrations and clean-ups. Within two decades the movement went global and now more than one billion people around the world participate in Earth Day activities.
In the early 1970s, incidentally, the Earth Day movement led to the creation of the U.S. Environmental Protection Agency and triggered such legislation as the Clean Air Act and Clean Water Act, all of which had bipartisan support during the Richard Nixon administration.
