Some think it is too late, mostly people with no knowledge about resources or simply blindly religious, but these blind religious people did not analyze the recourses we have on the planet and did not think long-term, something that is a good ability for a politician or anyone trying to get into it.
Because growth is unfortunately like an impossible hamster that thinks it can double for ever (Youtube-clip 1 min) eventually leading to environmental destruction, wars and cannibalism. So looking at population without looking at resources is down right imbecile and unfortunately there are many of these imbeciles around in western politics and that is what I try to change with the Swedish Scientific party.
