While I abhor imaginary best friends in the sky, I highly feel humans need more than just science (or our bastardization of it) to feel the responsibility to fix this issue (and the way to). There is room for something a little more; perhaps a sense of community and our integral place in it. Scientifically speaking, we are compose of the same very atomic particles of all matter and all nature. We are, on an atomic level, interchangable with the sun, trees, moon and all parts of the universe. Unfortunately, on a spirtual level, we lack this very sense of community and simple facts won't invoke it.
There is room for awe and divinity in the nature of our universe and our existence. We are part of the community of the earth on both an atomic and biological level--not its god-given owner, or even its "steward". We have followed these principles since the dawn of man and lived in balance with nature, symbiotically, for almost a hundred thousand years. Its been a mere blink--a fraction in time--that one technologically superior, growth obsessed group of homo sapiens has converted or conquered everyone else to push its infinite expansion upon the earth (using both science and religion to further their goals).
Lately I've been thinking that perhaps the Pantheists have a good idea, and even if its notion might strike some as "silly", the recognition of our instinct to live with nature and revel in the divinity of the universe is beneficial for our very survival. We are at a critical point in time...and honestly, I don't care what makes people want to change (if its the FSM, Im cool with that as well). But if you can't inspire people to do it with numbers, record droughts, famines even, then I say reach in your tool bag and figure anything else out. Otherwise, its extinction.
