Yes, it’s that time of year again, when liberals and Gaia-worshippers across America celebrate their High Holy Day. I am speaking, of course, of Earth Day. The Mother of all Earth Days was celebrated on Saturday, on the National Mall in Washington, DC, in a celebration dubbed ‘Global Citizen Earth Day.’

The group sponsoring the event produced a rousing video that promised entertainment from major names in the music industry.

The United Nations promised that Secretary General Ban Ki-moon would be present.
