April 22 was the 41st Earth Day. I remember the very first one. I was in 6th grade and our teachers made quite a big deal about conservation, clean air and water, and environmentalism in general. The American public was just beginning to catch on to the idea that we should take care of the place. NASA celebrated #41 by publishing some special photos of what we earthlings like to call Home, Sweet Home.
