I'm pretty cynical when it comes to faith in humanity to save us from ourselves. We're too selfish to make sacrifices to our quality of life that are not foisted upon us. I really do hope for some magic bullet of clean energy that will solve our problems; the warp core and matter-replicators will remove humanity's scraping desire for material wealth and usher in a new age of enlightenment. /dream big!

Rather, I think we're going to keep shitting into our water and atmosphere until we reach a tipping point to inspire massive change - probably long after our personal lifetime.
