Students could investigate the staggering decline in wild animals as compared to the huge populations of livestock animals and humans. Have students think about how they can connect this to sustainability.
This resource describes the Global Livestock Environmental Assessment Model (GLEAM), which is used to study the emissions from animal agriculture across the globe. This resource is rather technical but provides good descriptions of the terminology used and sufficient resources (via various tabs) to understand what is presented. This resource is best suited for older students and can serve as a good example of the types of information used in complex models. This resource is recommended for teaching.
