How did you celebrate Earth Day on Thursday? One group got into the spirit by taking a jab at Earth's closest neighbor. A billboard was spotted in Hawthorne, California, that read "Mars Sucks. - Earth". It was placed near the headquarters for SpaceX - the Elon Musk-founded company that hopes to send humans to Mars one day. Turns out, the billboard was from an environmental group called The Mars Sucks Project, sponsored by environmental groups like Greenpeace and World Wildlife.
There's even a MARS SUCKS website! lol
If humans ever colonize Mars, will they still celebrate Earth Day?
