It's hardly a revelation to say that climate change is bad, like we know, we don't need to be lectured by a 16 year old girl. The problem is that the solutions are incredibly complex because there's no Political will amongst the voting base, it would need every countries Politicians to make sweeping changes across their countries, changes which would lead to people going hungry, lead to a lack of money to care for old people and damage their economies irreparably. Every country would have to do this. The Politicians who made those changes would be voted out as soon as people started lining up for welfare and inflation and interest rates started to rise. People who support her and think that solving climate change is some easy thing to accomplish that isn't being done out of laziness or stupidity are literally brain dead to the point I wonder if they're capable of an original thought, go read a ******* book and learn some basic economics. Actually people lining up for welfare is best case, in some countries you'd have mass riots and civil war.
The sensible solution is to get countries to have something like a green fund that goes into researching technological solutions to environmental issues, building more nuclear power stations, working towards electric vehicles, less damaging forms of agriculture, etc.
