PFAs are extremely resistant ‘forever’ chemicals that have found their way into many of the products we use on a daily basis. Their strong carbon bonds make them difficult to break down, endangering our environment. How can we reverse the damage done by persistent pollutants? Do we have enough time to leverage natural processes to eliminate PFAs before it’s too late? We speak with Professor Andrew Tanentzap, researcher at Trent University and University of Cambridge, about how we can utilise natural microorganisms to break down carbon-based pollutants.

Professor Andrew Tanentzap

Professor Andrew Tanentzap is Canada Research Chair in

Climate Change and Northern Ecosystems at Trent University and a Member of the

Royal Society of Canada College. He is also a Bye Fellow at Peterhouse College,

Cambridge and was previously Professor of Global Change Ecology in the

Department of Plant Sciences and Conservation Research Institute at the

University of Cambridge from 2013 to 2023. His research is at the interface of

ecology, evolutionary biology, and biogeochemistry, making fundamental

discoveries in understanding how environmental change impacts both biodiversity

and the benefits people receive from nature, including carbon sequestration,

food production, and safe drinking water.
