Damian Carrington, the Guardian:

Their exploration of future fossils has led [Prof. Sarah] Gabbott and [Prof. Jan] Zalasiewicz to draw some conclusions. One is that understanding how human detritus could become fossils points towards how best to stop waste piling up in the environment.

“In the making of fossils, it’s the first few years, decades, centuries and millennia which are really crucial,” says Zalasiewicz. “This overlaps with the time in which we have the capacity to do something about it.”

Gabbott says: “The big message here is that the amount of stuff that we are now making is eye-watering – it’s off the scale.” All of the stuff made by humans by 1950 was a small fraction of the mass of all the living matter on Earth. But today it outweighs all plants, animals and microbes and is set to triple by 2040.

It is disconcerting to understand our evidence of civilization accumulated over the span of many tens of thousands of years, yet we have equalized that within just a few decades. We are converting so much of the matter on this planet into things we care about for only a few minutes to a few years, but their mark will last forever.

Gabbott and Zalasiewicz’s book “Discarded” is out now. I hope my local library stocks it soon.
