Kip talks to members of an environmental organization about why they do not talk about the harmful effects that animal products have to the environment. The gases that are released when raising livestock for food and drinks are more harmful than other fossil fuels.

He notes that the industry is destroying oceans, animals, and other water consumption problems. But Kip is also worried about why the government is not talking about this.
