Are efforts to colonise Mars justified?
- We might be hit by an asteroid or some object from space leading to total destruction of the planet; and hence we need a backup mechanism.
- We need to satisfy our curiosity and prove to ourselves that we CAN indeed conquer Mars.
- Satisfy our bloated ego.
- ...and you may add other reasons that are in favour.
I'm all game for advancement of science, knowledge, technology and engineering; but I firmly believe that all those efforts, time and money with the best brains available on the Earth may be deployed to save and protect our own planet.
What's your take?
