From the authentic website this:
Earth Day, observed by over 1 billion people, is the only event celebrated simultaneously around the globe by people of all backgrounds, faiths and nationalities.
The first Earth Day, on April 22, 1970, activated 20 million Americans from all walks of life and is widely credited with launching the modern environmental movement. The passage of the Clean Air Act, Clean Water Act, Endangered Species Act and establishment of the EPA soon followed. Growing out of the first Earth Day, Earth Day Network (EDN) works with over 22,000 partners in 192 countries to broaden, diversify and mobilize the environmental movement. More than 1 billion people now participate in Earth Day activities each year, making it the largest civic observance in the world.
And this from CityLab:
In 2015, Earth Day feels fairly anodyne. The litter pick-ups, the festivals selling recycled crayons, even the President's speech in the Everglades: It all seems quaint in light of the daunting climate issues we confront daily in the news. But if you, like plenty of our readers, look to cities for a bit of environmental hope, give a nod to Earth Day. It's what made [cities] look green.
