Earth Day Turns 43
4/22/13 / Matt Bruce
Sandwiched between signings of the Wilderness Act and the Clean Water Act, the first Earth Day was celebrated in 1970. A lot has changed over four decades of the environmental movement, but one thing hasn’t changed—the need to track metrics and gauge progress. Here at Corona, we thought it would be fun to dig into the numbers, and see what has happened around the world and around Denver since the first Earth Day.
