Metaphors are powerful. While many of us have the sense (often vague, sometimes acute) that human beings are living unsustainably with regards to the Earth, that feeling often reflects less fact than our prejudices against consumption. But when a scientist describes how we manage natural resources as “a Ponzi scheme for managing the planet,” chances are we’ll sit up and listen.
Nature Conservancy lead scientist Heather Tallis made just that case last October at the Chicago Ideas Week. She argued that human society is conducting what amounts to a pyramid scheme — using borrowed capital and receiving returns too good to be true — for the way we produce and consume agriculture, fresh water supplies, energy, timber and fish, as well as the ways in which we protect ourselves from storms and floods.
“In every one of these cases, we are making incredibly risky investments that are not safe–and we pretend that they are,” Tallis told the audience. “And in each of these cases, we have an alternative in investing in nature that’s much less risky.”
