The first Earth Day was celebrated on April 22, 1970. With support from Wisconsin senator Gaylord Nelson, a Washington, D.C. environmental group organized an event called the Environmental Teach-In to raise environmental awareness. This event became Earth Day. Earth Day spread from being recognized in cities and colleges in the United States to being observed in places all over the world.
Over one billion people from 180 countries around the world celebrate Earth Day every year.
See some pictures from the first EARTH DAY from National Geographic
The Earth
- The Earth is humongous, having a diameter of 7,926 miles. It orbits around the sun at a speed of 18.5 miles per second or 67,000 miles per hour. Seventy-one percent of the Earth's surface is water; the Pacific Ocean makes up 70 million squared miles of that coverage. The force of gravity is so strong that you would need to travel at a speed of at least seven miles per second to escape it. Approximately two million species of animals, plants and other organisms have been identified and named; it is estimated that approximately 50 million species have yet to be identified.
Incentives to Recycle
- If everyone in the United States recycled their newspapers, the lives of 41,000 trees would be spared. One single tree can detoxify the air of up to 60 pounds of pollutants.
To make an aluminum can from recycled materials takes only five percent of the energy normally needed to make a can, an energy savings of 95%. The energy saved by recycling just one aluminum can is enough to power a television set for three hours.
Recycling glass bottles allows the energy consumption for new glass products to be cut in half.
