The only way to address the climate and ecological crisis through our governments, is the war footing, @ProfBillMcGuire mentions. Obviously it is not the same as a war, and it must be as global as possible. The difference between the WW2 precedent and now, is that the aim must not be to return to business as usual as in WW2, but to transition to a sustainable society. One of the big misunderstandings, is that we can know now what a sustainable society would look like. We can only know for certain what a unsustainable society heading for collapse look like, and we are living in it. We can know roughly what we need to do and a lot of it is just stopping what we are doing now. However, creating an actual sustainable society, not heading for collapse, is going to need the collaborative thinking of many great minds (and just ordinary people) working together. In fact, this is one of the first necessities, moving from an artificial competitive situation, created by big egos vying for power, to a collaborative, cooperative situation. It would be an ongoing process. It must start by essentially freezing the current economy and transitioning it to a sustainable one. I know what people will say, that this is far too idealistic, it will never happen. But radical change is coming whether you like it or not. If climate change and ecological catastrophe, collapses our civilization, the change is going to be radical in the most frightening way. We will never be able to put our civilization together again. This danger is not in the distant future, but from now onwards. Our civilization is a lot less resilient than people think. The only thing that currently holds it together is the pursuit of economic growth, profit, returns on investments. But as soon as that becomes difficult it will collapse like a pack of cards, with nothing to hold it together. But if we cooperate and work for the common good, that will not happen. The only way to avoid collapse is people all cooperatively working together for the common good. Then if things get really bad, it won't fall apart like it currently will. It is not me being unrealistic. It is those who believe business as usual, will continue in the face of climate breakdown and ecological catastrophe, who are totally being unrealistic. We have a choice, ignore the climate and ecological crisis and face the collapse of our civilization and the starvation of billions (prior to the industrial revolution, the world only supported a population of less than 1 billion - the only way we can continue to feed 8 billion, is an organized economy, but not one organized in the present way). Or work together cooperatively for the common good to save ourselves. If you think I am being idealistically unrealistic for pointing out how can avert collapse, so be it. But I'm not the unrealistic fantasist. That is those are people who believe that business as usual can carry on. That there is somehow a way to avoid taking radical action by ignoring the climate and ecological crisis. No, if you just ignore it, you face the radical change of nightmares.
