Every April 22nd since 1970, people have celebrated the “holiday” called Earth Day. The day is meant to be a celebration of the Earth, a reminder that our actions directly affect the planet we live on, and a time to educate each other on environmental matters. Each year, organizers pick a theme to shine a light on a particular problem facing the planet. Earth Day has come to be embraced as a day for people to volunteer their time to help in a project to better our planet. In keeping with the spirit of Earth Day (if not the year's chosen theme), we've collected a series of apps that will help you learn more about our planet and strategies and tips that you can use to help save it.
