Earth Day 45

First organized in 1970, Earth Day is a day set aside to remember and appreciate the Earth's environment, and our responsibilities and roles within it.

In the past 45 years, the population of the Earth has doubled—75 percent of the people alive today were born after 1970—and the increased demand on our limited resources makes sustainable solutions even more important.
