Scientists have been saying these same things my entire life. While they are absolutely correct, the necessary change does not seem to be a priority for leaders. At best it gets lip service and underwhelming commitments. At worst conservatives completely deny the problem. We have social issues blocking our scientific solutions.
I don't think our existing leadership is capable of being proactive, we are always slow and reactive. We need more radical social change, which I only see happening once a certain generation dies and another takes their place.
It's so ironic how many downvotes this is getting in the context of this thread.
