5) Peters et al. (2016) examined the impact of different human diet scenarios on the carrying capacity of the human population in the United States. The "baseline dieť" is the current average diet of Americans which includes a high proportion of meat and dairy products. The study compared the baseline diet to a vegetarian diet (which includes both egg and dairy products) and five omnivore diets.

Question
5) Peters et al. (2016) examined the impact of different human diet scenarios on the carrying
capacity of the human population in the United States.
The "baseline diet" is the current average diet of Americans which includes a high proportion of
meat and dairy products.
The study compared the baseline diet to a vegetarian diet (which includes both egg and dairy
products) and five omnivore diets. The 100% omnivore diet scenario proposed that 100% of
Americans are eating a healthy diet including meat, dairy, and vegetables with the primary
source of protein coming from meat products. The other omnivore diet scenarios decrease the
proportion of US population eating meat products and increasing the proportion of people on a
vegetarian diet (no meat products consumed). For instance, the 60% omnivore diet scenario
assumes that 40% of the US population is vegetarian.
Below is a graph showing the predicted carrying capacity of the United States under these
different diet scenarios.

A) Based on how energy flows through ecosystems, explain why human populations with a
higher proportion of vegetarians have a higher predicted carrying capacity?
B) Based on energy flow dynamics, briefly discuss how transitioning to a more vegetarian diet
would impact land use by humans and the conservation of biodiversity in North America.
