i think it depends on who remains in control in the political arenas.
right now we have politicians who are willing to obscure the issues and blame other factors, or pretend it doesnt exist, in order to not deal with the realities of how it will effect business and buying habits. they want to keep making money. they will put money into smearing and belittling to keep it from being a relevant issue, just like they put money into keeping their position.
I think there are many people who will follow that lead, because admitting the earth is in trouble is just too damned scary, and trying to change the habits of a lifetime and give up all the wasteful perks of living the entitled life we lead brings out the greed, racism and ill will inherent in our social structure.
i think what could possibly save us is technology, and awareness. but it might just take a revolution, or war, to overthrow the people at top who just dont give a damn.
