@Oyster: Heh, what good is your personal profit when you're dead, anyway? I can never fully wrap my head around that kinda profiteering myself, but that's probably because it isn't so high on my agenda. Anyway, interesting question you bring up.
My opinion is that, for the first time in history, we are becoming conscious of our interactions with our habitat at a biospheric level: instead of thinking only about local environmental health, we're beginning to analyse the big picture. Simply put, we're going into another alien territory, exploring our own planet more deeply than Magellan or Cook have -- we're exploring what makes it tick the way it does. If you look back in history, industrial pollution has had many sources, and can probably be attributed to some effects. Population health was the primary concern, and so we began to single out products that provide direct, active harm to the human body: lead pipes, for example.
However, we're now looking beyond the health of singular human organisms, and toward the health of the greater Earthly organism, the interconnection of species as is understood by modern ecology. It also doesn't appear to be something we yet fully understand, because a lot of the yelling has to do with increasing temperatures, rising sea levels, and the like; sea levels and temperatures fluctuate through history, and though industrial output exacerbates it, we're not looking at increases that are supremely higher than they were 13,000 years ago. The problem is human, but it's in regards to the territories we occupy now: humanity stretches almost all the way across the globe, from coasts to mountain.
Technology exists as a means for the human population to live efficiently with its environment, whether it is man-made or the natural one: a problem in the environment, be it simply that communication is too slow between locales (telegraph, telephone, radio, TV, cell phones, e-mail) or that we can't live out in the open in the natural environment (housing), is generally responded to by a modification of that environment. Therefore, the only natural course that I can see is to modify our environment again, with technology, towards a more normalized setting. This isn't to say that we completely subvert the natural process, but rather help to restore the natural process to being natural, rather than driven by humans.
Hubris, maybe, but it seems that humans are best at manipulating specific environments.
