Most space fans hope that humans will eventually reach Mars. As for cows and chickens, that’s another question.
Animal rights group PETA (People for the Ethical Treatment of Animals) has sent a letter to space entrepreneur Elon Musk, founder of rocket company SpaceX, urging him to make any SpaceX missions to Mars vegan.
“We can get off on the right foot on our new biosphere by ensuring that SpaceX crafts traveling to Mars are stocked only with vegan food and that Mars’ colonists commit to enjoying an animal-free diet once they’ve arrived,” the group wrote in the Aug. 8 letter.
