It's the 50th anniversary of Earth Day! Our planet has been around for way longer (super duper amazingly incredibly mind-bogglingly longer!) but people only started officially celebrating Earth Day on April 22, 1970. It was the birth of the modern environmental movement, and today there are Earth Day events and activities in more than 190 countries. You can play a part in protecting our planet, too - everyday, not just on Earth Day!
You probably already recycle and do your best to save paper and electricity. Maybe you help take care of plants at home or participate in Eco Kids Club at school or the library. Looking for more green ideas? Check out some books about environmental issues you care about, like endangered species or clean water.
