Earth Day, celebrated each year on April 22, commemorates the birth of the modern environmental protection movement. Started in 1970 during an era when pollution was rampant in our country, Earth Day is credited with bringing the concept of environmental protection into the national political agenda. The first Earth Day was marked by massive rallies and demonstrations advocating for a healthy and sustainable environment. In 2017, Earth Day will be marked by a national call to action around science, with a march in Washington DC and other communities throughout the nation.
