Senator Gaylord Nelson of Wisconsin came up with an idea to raise awareness of environmental issues. On April 22, 1970, Earth Day was born. Demonstrations took place across the United States to protect our planet Earth from pollution and deforestation. Groups picked up litter and planted trees. Earth Day is now an international celebration. About one billion people observe this day every year. There are many more things that humans can do to continue to protect our Earth. This year’s theme is “Invest in our Planet.” Do it!
