I don't think this hope is warranted. Our species is doing awful things to the planet:
* Animals and plants are dying at a mind-boggling rate. This has consequences for us eventually too, but on it's own, this is an atrocity.
* We're stuffing the air, sea and water with plastic, PFAs, insecticides, herbicides, etc. This will also have consequences for us.
* Our polar ice is melting, our vital weather systems collapsing, our topsoil eroding, our old growth forest near forgotten. As noted above, our oceans are doing some terrifying shit. Consequences are imminent.
* Inequality exacerbates all the above, and gives me serious doubt as to how our children will actually fare. Climate refugees are already a thing, and it could get soo much worse if our current path is maintained.
A stunning proportion of our leaders, megacorps, media, banks, and institutions are making this all worse. They subsidize and invest in fossil fuels, arms, big agri etc. They provide cover for them, enable them, and profit from them. They savagely beat anyone fighting against their acts into submission; sometimes with mortal methods, sometimes just with smears and legal abuse.
Have you considered any of this in your declaration of "we're in the best place ever"? I feel like we have a responsibility to our children and grandchildren to be honest about our fuck-ups.
