> So what does that realistic optimism look like? I think it looks radical, literally: we have to expect, in a world that has well and truly tackled climate change, things like car travel becoming a thing of the past, replaced by bikes, cargo bikes, trains, and airships. (As an aside, "climate change" is just the beginning, we have entered the so-called Anthropocene Age, and that comes with vast responsibilities. E.g. what to do about "non-native invasive" species? Shall we garden the whole Earth? https://en.wikipedia.org/wiki/Anthropocene https://en.wikipedia.org/wiki/Anthropocene ) Expanding on the no-more-cars thing: EVs are a stop-gap, it doesn't make sense to put batteries in cars. But even if the whole fleet of ICE vehicles were to be converted to battery-powered EVs we still have to deal with the tire pollution! We can't have all that vulcanized rubber grinding against all those millions of kilometers of asphalt. It's one of the single largest sources of particulate pollution. Go check. It's fucked up. We're going to have to seriously re-imagine and reconfigure our economic systems over the whole globe. We might could have a resurgence in sail-powered cargo shipping: https://postcarbonlogistics.org/ https://postcarbonlogistics.org/ https://www.sailcargo.inc/ https://www.sailcargo.inc/ (As opposed to the current very cheap but very polluting system.) I believe we can live in harmony with nature (that is, increasing life rather than destroying it by applying ecological science), and that we can do it and maintain our populations (no genocide or mass starvation or any of that) and maintain a decent standard of living for the everybody. We just have to apply the technology and resources we already have efficiently. We will still be subject to the human condition, but at least we would have time to work out all our other problems, eh?
