Since 1970, Earth Day has raised awareness on some of the most important environmentally critical issues, from recycling to global warming. It's grown from being a small grassroots campaign centered in American cities to a global celebration that crosses continents.
Earth Day has helped the "Green Movement" immensely, but more than just raising awareness, Earth Day has always been an appreciation of the planet's natural beauty.
