Editor’s Note: We cannot have infinite growth on a finite planet. Something that should be a part of common sense is somehow lost in meaning among policymakers. In this piece, Elisabeth Robson explains the concept of overshoot to explain just that. She also delves into how the major policy makers have ignored it in favor of focusing on climate change and proposing “solutions” of renewable energy. Finally, she ends with three presentations on the same topic.
Bill Rees spent a good part of his career developing a tool called the ecological footprint analysis — a measurement of our collective footprint in terms of the natural resources humans use each year and the waste products we put back into the environment. His analysis showed that humanity is well into overshoot — meaning, we are using far more resources than can be regenerated by Earth, and producing far more waste than the Earth can assimilate.
Overshoot is like having a checking account and a savings account and using not only all the money in our checking account each year, but also drawing down our savings account. Everyone knows if we spend down our savings account, eventually we’ll run out of money. In ecological terms, eventually we’ll run out of easily-extractable resources and do so much damage from the pollution we’ve created, life-as-we-know-it will cease to exist.
I don’t like using the word “resources” to describe the natural world, but it is a handy word to describe all the stuff we humans use from the natural world to keep ourselves alive and to maintain industrial civilization: whether that’s oil, trees, water, broccoli, cows, lithium, phosphorus, or the countless other materials and living beings we kill, extract, process, refine, and consume to get through each and every day and keep the global economy humming. Please know that I wince each time I write “resources” to represent living beings, ecosystems, and natural communities.
