@fChk That's your considered view. Well with the present state of affairs and rate of increase of population, the Earth wouldn't be able to sustain the whole of humankind, with increasing pollution, industrialization and urbanization. (...)

Why should it ?

Every ecosystem tends to an equilibrium given the forces at play. Indeed, since the Industrial revolution (3 centuries ago) human-beings' footprint on Nature's ecosystems has gotten larger and larger (this is how Capitalism thrives!) The Earth's response will just tend to adjust to a new equilibrium where the conditions for the survival of mankind isn't optimal thus curtailing its nuisance on Nature's ecosystems !... That's how it works.

And if we don't succeed/survive on Earth, we won't (and don't deserve to ) succeed/survive anywhere else in the Universe at large, IMHO.

What's killing us is this disease that's called Capitalism and the greedy for-ever profit/growth mentality that it inculcates to its disciples... Let's start here to tackle the real problem of the current misery that's facing the 99% of the World population... and not get carry away with the silly idea, promoted by the percent-ers (1%) -via movies.. etc-, that our solution is extra-terrestrial.

(...) And says why it belongs to the SciFi genre. It very much is related with the reality, and don't forget we already have a Rover on the Mars.

.. because it does. Having one (or an armada of) Rover(s) up there, doesn't make human inhabitation of Mars possible :-)

Fifty years ago, NASA claimed to have put a Man on the Moon (I'm not saying they didn't, but I'm always cautious, when it comes to US propaganda...) and, here we are today... as far away from it as ever.

Look, I understand your enthusiasm for that idea (especially if your country is involved in the exploration effort) but facts are facts.
