This is why we won't ever fix it.
I think I see what you mean, I must admit I don't really agree with this statement.
I think we (meaning people) can actually fix this by applying pressure to governments to implement the necessary measures/taxes/etc to the polluting corporations all over the world. This pressure can have many forms - protest, boycott, etc. Also, it should be intersectional since climate justice without social justice doesn't really mean anything - it's just an empty vessel with greenwashing tendencies. At least the way I see things.
So many things to say, but I'll be super brief.
It's quite common that people who come from colonial countries, they are taught to ignore that one of the reasons that they currently have a higher standard of living as societies (not as individuals) in comparison to the places their ancestors went and colonised is because they took/expoited/stole/etc the resources from these places, including people. In the process the colonisers also trashed the place, as well as local, thriving communities.
So the way I see things, there are stuff that needs to be acknowledged first. Solutions come after.
