That's not a threat, it's an opportunity.

Really.

Applications are being accepted for those of you who are sick of this planet and want to go to a different one.

At mars-one.com:

"Mars One is a not-for-profit organization that will take humanity to Mars in 2023, to establish the foundation of a permanent settlement from which we will prosper, learn, and grow. Before the first crew lands, Mars One will have established a habitable, sustainable outpost designed to receive astronauts every two years. To accomplish this, Mars One has developed a precise, realistic plan based entirely upon existing technologies. It is both economically and logistically feasible, in motion through the integration of existing suppliers and experts in space exploration.

We invite you to participate in this journey, by sharing our vision with your friends, by supporting our effort and, perhaps, by becoming the next Mars astronaut yourself."

But you better like it there because you're not coming back.

Think long and hard about it.

Imagine if you had to bunk with Sheldon from The Big Bang Theory?

You might live long but you most definitely wouldn't prosper. :-P
