BBC Radio 4 – BBC Inside Science, Human use of plants beyond the limits of history.

Human impact on planet earth’s plant life might be detectable several thousand years back in fossil pollen cores taken from mud columns around the world. As Suzette Flantua and Ondrej Mottl describe in a paper published in the journal Science, a rapid acceleration in the changes in pollen species goes back further than we might have expected. This matters particularly when it comes to decisions around re-wilding and re-planting areas today in the name of conservation. As they hope to build on in future work, learning more about the state of ecosystems further back into the past might prevent us making the mistake of simply recreating different types of post-agricultural situations which might not solve the problem we are trying to fix.

One of the biggest impacts on the earth’s flora today is of course influenced by our meat consumption. The BBC’s Melanie Abbott has been to see a new exhibition opening at Oxford University’s Musuem of Natural History. Produced in association with the University’s Livestock, Environment and People research programme, this exhibition “Meat the Future”, seeks to raise awareness of the issues for health and the environment around eating – or not eating meat – and is open until January 2022.
