There is but one reason why it is polarizing. It is a serious problem and it is very difficult to solve. So there are 2 camps - those who "care and don't know how to fix it" and those who "don't care and don't know how to fix it".

Perhaps a solution is in order. I do suppose having humanity's global socioeconomic system running on a few ten's of thousands of raspberry pi's is a good start. Then those who care can continue to solve the problem while those who don't care are free to f*ck off to pollute some other planet (though they shouldn't do that either).
