You know, for a while I wondered why Earth day was on Lenin's Birthday Vladimir Ilyich Lenin (22 April 1870 – 21 January 1924), was the godfather and founder of the modern communist movement. I suspected that the environmental movement is just a cloak for anti-capitalistic activities since capitalism is the great satan to the communist and other hard and softcore leftist that hang around the Western based societies like parasites. You will not find them anywhere else. They are with us because of our laws protect idiots, and other places rule of law is a nasty gulag or a 9mm bullet in the ear.
The following defination is complimentary of Wiki
Earth Day is a day that is intended to inspire awareness and appreciation for the Earth's natural environment. Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. While this first Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 175 countries every year. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues. In 2009, the United Nations designated April 22 International Mother Earth Day.
