I understand that you have some concerns about global population. And crashes are not pleasant at all. It will be a horrendous experience with terrible suffering. Today, many researchers want to use captive chimps as bio-medical subjects for experiments on aging so that members of the human species can live longer. That just doesn't make any sense to me.
Science is supposed to be rational.
You studied captive chimps for 30 years. That was one of the most amazing experiences in my life. Intellectually I knew about it, I'd read about it. I'd studied chimps for 30 years in America, where they don't belong at all. In Africa I was finally seeing them in their home, and experiencing what it's like to be a stranger among them.
