Environmental Impact of Livestock Practices

The video discusses meat production methods, focusing on the environmental impacts of overconsumption and production efficiency. It compares CAFOs and free range grazing, highlighting their pros and cons, including land use, waste management, and energy efficiency. The video also addresses global consumption trends and their environmental implications.
