'Eco-Optimism'?

Gaia Vince (Author, Journalist and Broadcaster) claims that our 'extraordinary capacity to adapt' may well enable humans to overcome the effects of climate breakdown (https://www.theguardian.com/commentisfree/2023/apr/11/climate-breakdown-climate-crisis-solutions-idea). Vince's 'eco-optimism' is rooted in the belief that the extraordinary capacity of humans to adapt, has been key to our success in the past. She maintains that 'radical, pragmatic solutions, all begin with an idea' and, when change occurs, it can happen extremely quickly. This could be dismissed as a sermon on the power of the technofix but I don't believe that this is her point. Vince thinks, far from feeling doomed, we simply have to be brave enough to change things. Individuals can, she feels, collectively decide to do the right thing(s), producing a healthy, liveable world for all. That's, however, making a number of optimistic assumptions. The first is that we have sufficient time, for societal change to counter the climate crisis. The second is that there's such a thing as a world-wide 'society', all prepared to make these changes. Members of the human population often don't have any of the choices regarded as available to folk in the more affluent parts of the world. Affluent folk can be generally unwilling to give up their advantages. Poorer folk also would like to have them. Thirdly, many industrialists and politicians are very resistant to even contemplating allowing 'society' to change in directions that don't suit them. Finally, unfortunately, the historical adaptive 'successes' (patchy, at least?) of our species, have actually little relevance to today's problems. There's never been 8bn of us before. We've never had such an impact on our planet. A little 'guerilla gardening' certainly aint going to fix things! It's good to be positive but realism is also required, if humans are going to extract themselves from a mess of their own creation.
