I'm almost 70. First learned about climate change in 1972. Back then I was certain we would prevent at least the worst of the results, because we were passing good laws around pollution and environmental issues. But no, big time capitalism decided that short term (a few decades) profit was more important to them than leaving behind a habitable planet for their great grandchildren. I presume they thought that, being ultra rich, they would be able to either escape to another planet or build viable domes to live in.
Please don't tell my son, but I sometimes wish I'd chosen abortion. Now he has 3 children, and I cry for their future.
