Earth Day just hit its 50th birthday.
Wednesday marked 50 years since Earth Day was started in 1970, according to the Earth Day website.
The day was started by Wisconsin Sen. Gaylord Nelson and took off in the U.S. with the help of activist Denis Hayes.
The purpose of Earth Day was to fight against pollution, the loss of wilderness and the extinction of wildlife, the website said. And in fact, the day even led to the creation of the U.S. Environmental Protection Agency.
Since then, hundreds of environmental organizations have been founded, focusing on all different aspects of the globe.
This year for Earth Day, FOX Business found the top-rated environmental organizations listed on Charity Navigator to see how much the groups make.
The five that made it to the list all had four-star ratings, worked internationally and had $13.5 million or more. The organizations also had their impact information listed on Charity Navigator.
Here are the groups that made it to the list.
