A sure sign that folks are troubled by spikes, shortages and slumps:

slug power generatorsI had a dream last night that we solved the energy crisis by forcing the animal kingdom to create energy for us, but the trick was picking an animal ugly and unlikeable enough that the least number of people opposed the enslavement. So in the end, we had these enormous generators pushed by massive armies of slugs on land and eels in the water that created the entire world’s energy needs.

There were of course, slug and eel appreciation societies that picketed the energy companies but most people didn’t mind because they hated the selected animals so much.
