I disagree and would like to point out that "12 years" is a strawman. You've got to think a bit more long-term and about all effects on the environment and living conditions as a whole. If you take an unbiased look at climate change, resource exhaustion, and species extinction, then it becomes hard to believe that mankind will have the conditions to thrive on Earth in 200 years from now. It may be possible, maybe with technological inventions, but it certainly doesn't look that way. We're only about 200 years into massive industrialization and have already damaged Earth on an unprecedented scale. The current species extinction graph alone should worry people way more than it tends to do right now. Changes to the oceans are also extremely alarming, because certain conditions in the oceans could trigger a collapse of most of the ecosystem.
