There are 100,000 people registered for a one way journey to Mars says a report. http://www.theregister.co.uk/2013/08/12/mars_one_hundred_thousand_applications/
They have registered for one way, meaning they don't mind not coming back.
One view is, it is a great achievement, able to go to Mars. Like flying to the US, in the near future man will fly to Mars, which is more than 200 million miles away(average distance). From day one, we will have a cellular network their, Cogo-Coola and Facebuk account getting operated from Mars.
Mars will have evolved humans who know to increase carbon footprint from day one, unlike earth seeing an evolving destruction.
On the other hand, mankind has enough of land to be taken care on the earth. For instance in India with one of the densest population in the world, the arable land to population ratio is approx. 1 acre to 1 person even now.
We are already discussing about highest level of carbon dioxide emission levels which could endanger humanity.
Mars is definitely a solution to escape from earth. But it will be of an 'Elysium' type, a solution for world's richest.
Mars is only 11% of earths mass and if that can be a solution, definitely saving the world is an easier, and a solution for all human beings.
