When discussing the environment with non-converts, the debate often degenerates to someone commenting “you want us to go back to living in caves”. The sentiment reveals a shocking but widespread ignorance about the vast quantities of energy and materials that we squander. Energy is cheap and ubiquitous, and it seems that humans are doomed to waste whatever is abundant.

In fact, we could reduce consumption by over 90% and still live better than kings and emperors did 300 years ago. (Yes, monster truck rallies would have to go. If by “living in caves” you mean “stop driving my Hummer around while Tweeting on my cell phone”, then I stand corrected.)
