Video: Heather Tallis on ‘The Ponzi Scheme for Managing the Planet’

Dr. Heather Tallis from Chicago Ideas Week on Vimeo.

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.”

    Excellent presentation … succinct, impactful and forward looking. I liked the fact that she illustrates how it is cheaper to practice good conservation practices and partner with nature to keep our water clean than to clean it up later. She then continues the same theme with other natural conservation solutions to real challenges that cost less to implement than many current method the salt marsh barriers to protect coastal development. $$ talk and hopefully this message can reach more and more of those policy and decision makers who can change the way we do things.
