An argument to colonize Mars had gained considerable strength recently with some prominent scientists and business leaders expressing interest and drawing up plans to do so. Mars, we are told, is very similar to Earth because of its similar diurnal cycle, existence of atmosphere, presence of water and even the possibility of life. People however lament about the distance, the difficulty of aligning a spaceship towards Mars and difficulties of communicating with earth from so far away. But for the continuity of mankind, it is argued, it is essential to colonize another planet because a catastrophic event can happen anytime on earth – an asteroid hit or a war which leaves earth a nuclear wasteland.
Except that these two catastrophic scenarios are not the same. The first is a cosmic event over which mankind has little or no control. Humans themselves, however, will cause the second. Despite the dangers of a full blown nuclear war being known now for nearly eight decades, mankind’s appetite for proliferation of weapons of mass destruction continues to increase unabated. Even if the existing nuclear stockpile was used in the event of a third world war a nuclear catastrophe on earth is assured. So the question arises that even if the humans were able to escape the nuclear catastrophe on earth and colonized Mars, will this scenario not replay again there. And if they escaped Mars and the same self-destructive event happened there they will need to go to another planet, then another planet and so on. If mankind continues to develop technical abilities to develop more and more sophisticated weapons but at the same time continues to survive by hopping on to other planet(s) then in time the destructive capabilities of these weapons is bound to increase exponentially. It will then become just a matter of time whether humankind’s ability to find newer worlds can keep ahead of its capability for destroying itself. And we will be back to the situation that we are at at present.
So before we colonize Mars, humankind may have to first confront its self-destructive tendencies, which lie deep in its brain make up. Otherwise the effort to colonize Mars may be a futile effort. Business and scientific leaders and organizations who are focused on the technical (Musk, Enriquez, SETI etc.) aspects of colonizing Mars may want to first focus their efforts on how to make the human brain more capable of survival in the long run. Even if we do not get to Mars, such advances may make life better and more sustainable here on earth.
