Food and the long term risk to life

A Cambridge article explores our research on how food consumption affects the extinction risk of 30,875 land-dwelling animal species, with an interactive tool to examine biodiversity impacts across different countries and diets.

Jacqueline Wilson wrote a brilliant article about our recent paper on the biodiversity impacts of food consumption up on the main Cambridge website, complete with interviews with Thomas Ball and Alison Eyres.

How does your dinner affect the risk of 30,875 species of land-dwelling animal going extinct?

Dr Thomas Ball can tell you. Depending on what you’re eating he can calculate the likelihood of the global demise of every mammal, bird, amphibian and reptile over the next 100 years. He’ll tell you that not all dinners are equal. -- cam.ac.uk, 2025
