A previously-unmentioned wrinkle in the most feasible plan for humanity to reach a second planet: meat eaters will be left behind to languish on Earth. Russia Today writes:
A US billionaire and co-founder of PayPal, Elon Musk, has made plans to build a settlement for 80,000 people on Mars when technology makes it possible for man to live there, for a price of $500,000.
Musk is a considered one of America’s most respected private space entrepreneurs and was in charge of creating SpaceX, a space transport company that produced the Falcon 9 rocket that delivers NASA cargo to the International Space Station. The billionaire’s estate and prominence in the space industry could make his plans [for a city on Mars] feasible, but the California-based engineer has not left behind his personal ideologies: Musk will only allow vegetarians to live in his settlement.
