Schools purposely don't enforce that concept. The science curriculum in Earth Science and Living Environment(Biology) focus on the fact that we're 'ruining' our ozone layers and greenhouse gases(us) are responsible for 'climate change' and that it is our duty to do something about it.

So you have adults who are totally okay with shit like this because its for 'the greater good' and that's what they learned in school and how can they be wrong?
