Yup, I watched that work really well in South Africa. Not. Sorry, even if one does listen to some people, there is no guarantee that it will be a two way street.

People essentially protect their own tribe, and that's it. Nothing is going to change that. At this point, the only sensible thing to do is find a place that is relatively safe from climate change, get together with a bunch of people you can live with in an intentional community, and forget about the rest.

There is no hope.
