perhaps the inverse is true, we send a load of people and a spend a huge amount of resources to be able to make an inhospitable planet, hospitable, through the means of huge domes etc.
Perhaps then we will realise how fortunate we are to have a planet where this is not required and that may cause us to increase our efforts to save earth.
I would agree however that finding a hospitable planet that did not require 'terraforming' would be the death knell for the earth. Mainly because the rich/powerful would see their exit and would happily use all of earths remaining resources to get themselves there even if it was at the cost of most of the rest of the population of earth and earth itself.
