Earth Day, which was first celebrated on April 22, 1970, has now reached more than 190 countries.

The purpose of Earth Day is to raise awareness about the environmental challenges faced around the world. The theme for 2017 is “Environmental and Climate Literacy.”

More than 100 billion people participate in Earth Day events every year, which makes it the largest civic observance in the world, according to Earth Day Network.

In an effort to join in on the festivities, many Ball State and Muncie organizations are hosting events.
