One straightforward route to fixing all of that consumerism is a carbon tax. People will consume less when it costs more. But no carbon tax will be passed, because of denialists.
You can reduce your own consumption, and a lot of people do. But that's not sufficient, and it gets less sufficient every day. The longer we took to act, the bigger changes were required to deal with it. And it was the denialists that prevented action.
Industry played a big part in convincing them, but they made the individual choices to believe corporate shills over scientists. So yes, I blame them.
