There are twice as many people on the earth now than when I was born. The rate is slowing, but the population is still growing. The UN predicts there will be 9.7 billion people by 2050. So the problem won’t be self correcting until it is far too late. Scientists have been warning of a point of no return most of my life, which was promptly ignored, or actively refuted by anyone with the power to do anything about it. We blew past that point years ago, and still aren’t making much progress. So, pardon me if I don’t share your optimism, even as bleak as it was.
