Yes I agree with you! Greed is at the heart of our predicament. I just think that the focus on CO2 emissions as the main problem is missing all of the other planetary boundaries we are crossing. There is an ecological problem in addition to the economic one. Without a doubt the economic problem has multiplied the harm of overpopulation manyfold, wealthy and exploitative countries are disproportionately to blame for the dangers we face, and we should seek new ways of living that are not inherently exploitative to minimize the loss of life as we adjust to drastic change.
