During the last century, evolutionary biologists developed the idea that power (defined as the rate of energy transfer) is key to the survival and success of species. This notion was formalized as the\u00a0maximum power principle<\/em>, which biologist John DeLong has explained as follows:<\/p>\n

\u201cbiological systems organize to increase power whenever the system constraints allow. . . . With greater power, there is greater opportunity to allocate energy to reproduction and survival, and therefore an organism that captures and utilizes more energy than another organism in a population will have a fitness advantage.\u201d[1]<\/a><\/p><\/blockquote>\n

The 20th<\/sup>\u00a0century seemed a propitious time for such an idea to arise, as one species\u2014ours\u2014<\/em>was in the process of gaining unprecedented power by harnessing the energy of fossil fuels. Coal, oil, and natural gas constitute tens of millions of years\u2019 worth of stored ancient sunlight\u2014energy that\u2019s vastly greater in quantity than any energy sources humans had harnessed previously.<\/p>\n

Constraints on all sorts of human activities were suddenly lifted. Soon we were out-competing all other organisms and, in effect, taking over the world. During the last two centuries, human\u00a0per capita<\/em> energy usage grew eight-fold\u2014while the number of \u201ccapitas\u201d also doubled three times over. All this newly available energy found uses in agriculture, mining, manufacturing, transportation, and warfare. Today, just through mining, we displace far more of the planet\u2019s crust each year than do all of nature\u2019s processes (wind, rain, and earthquakes) combined. Human-made stuff now outweighs all of Earth\u2019s biomass. It\u2019s been the biggest power grab on this little planet of ours in tens or hundreds of millions of years…<\/p>\n
