We take it for granted, we believe that we have the right to exist. At every turn we're trying to defeat death and illness. Trying to defeat nature's (and the planet's) mechanisms of a form of population control.
Then on the other hand, we sort of complain about overpopulation.
Don't get me wrong, I don't want to see people die, but on the other hand I fully understand that we must die. Me must get ill.
