I still firmly believe human overpopulation is the greatest threat to the planet. Global warming is sexy while overpopulation is arguably the least sexy political platform today for any politician to tackle. Exchanging gasoline powered automobiles for electric and reducing individual carbon footprints isn't going to matter a lot as long as increasing world population results in increased energy consumption, more pollution, deforestation, destruction of ecosystems, etc. Go watch Our Planet on Netflix if you want a sobering reminder of what overpopulation is contributing to the worlds forests, bodies of waters, extinction of animal and plant life, etc.
