On April 22, more than one billion people around the world will take part in the 43rd Anniversary of Earth Day. Communities around the world will voice their concerns for the planet, and take action to help protect it.

In the face of unprecendented occurences of extreme weather, loss of species, and pollution, it is more important than ever that communities do their part to help protect the planet.

See what universities can do to take part here.
