Climate Change and Biodiversity Loss

Wednesday, October 1, 2025

We are currently living through the sixth mass extinction since fossil records began. This video describes previous mass extinction events and the causes of the current one - mainly habitat destruction for livestock production, pollution and climate change. Some 1/3 of all species are expected to go extinct, with some ecosystems, such as coral reefs, most severely affected. People will also be affected, as rivers dry up, rising oceans flood coastal regions and crop yields decline. The livestock sector currently contributes around 16% of all human-generated greenhouse gases – more than all forms of transportation combined (at 13.5%). This is set to substantially rise, as global consumption of animal products doubles, by 2050. Mitigation options are discussed. Only substantial changes in consumption patterns can realistically achieve the reductions necessary to prevent catastrophic climate change.
