You're completely ignoring the political realities of the world we live in. Of course there are a million solutions but try to get Joe Manchin to go against his own self interests and move off coal. Try to get Putin to stop putting the squeeze on Europe so they're using more natural gas (a fossil fuel made of methane) and calling it green. Try to slow down Modi and his growth policies in India. How about China using more coal than it used to. The Paris Climate Agreement has for all purposes fallen apart because none of the signatories lived up their promises. We were going to compensate the countries in the Southern Hemisphere who are suffering as a result of our emissions. Not one penny has been forthcoming.

Goodall is right but give her regeneration message to the people who make all the decisions in the world around CO2 regulation. There is only one thing that counts - vote in politicians (not Republicans) that care about climate change. Not one Republican Senator voted for Biden's climate change bill - where were Collins, Romney and others who are smart enough to know something has to be done about it, but always put their party loyalty first? The ultra-conservative Supreme Court has also tied Biden's hands at the EPA as well.

How do we solve the problem of human stupidity and greed? Perhaps regeneration - a whole new species of us that will be more sensible, and come along in another hundred thousand years. That's our best hope.

Perhaps Goodall is right after all! I however believe that before regeneration happens, like Enrico Fermi has predicted, technologically advanced civilizations like ours, have a high probability of wiping themselves out through their own hubris and ignorance.
