This week’s episode discusses the impact of animal agriculture on the environment, what a plant-only agriculture system would look like, and some strategies for reducing methane emissions by cattle.

Here are the papers I discuss in this episode:

1. Nutritional and greenhouse gas impacts of removing animals from US agriculture
2. Inclusion of Asparagopsis armata in lactating dairy cows’ diet reduces enteric methane emission by over 50 percent
3. A heritable subset of the core rumen microbiome dictates dairy cow productivity and emissions
