On April 22, the world celebrated the 42nd annual Earth Day, a global event meant to celebrate the Earth and raise awareness for environmental causes. Even though it's nice to see how far we've come, images from around the planet remind us how much work is still to be done.
”International Earth Day” was first celebrated in 40s of the 19th century. 22 April, 1882 was officially celebrated as “Tree Day” in the US state of Nebraska. Based on the suggestion by the United States Senator Gaylord Nelson in 1970, the name of “Tree Day” was changed to “Earth Day” with the purpose to raise the attention to environmental issues, environmental pollution, and importance of nature.
