Earth Day was started in 1970 by a Wisconsin senator named Gaylord Nelson who was interested in environmental issues after witnessing the destruction of a California oil spill. What started as an American teach-in day has since grown into an global effort, with events now taking place worldwide.
Around 500 million people take part in Earth Day activities each year, and in 2009 it was designated as an International Holiday by the United Nations.
If you are interested in taking part in an Earth Day event, head over to Earthday.org, where they have a huge database of beach cleanups, recycling drives, tree plantings, and much more.
Also, please take a look at the fantastic infographic that I have posted after the break. I try and talk about conservation on AaD as much as I can, but this graphic really sums up the effect we have on animals due to climate change, poaching, and habitat loss .
