This coming April 22 marks the 51st anniversary of Earth Day - an annual event for showing support for environmental protection. Nonprofit organization Rainforest Trust has released "Seven Ways to Help the Environment."
Earth was first started in America in 1970 as a day to praise the planet. It is celebrated every year to raise public awareness about environment safety.
Today is the 45th anniversary of Earth Day, and to celebrate NASA has planned a series of activities to celebrate the beauty of our little corner of the galaxy.
