Text Solution

Verified by Experts

The correct answer is:

The idea that if everyone became vegetarian, Earth could support more people has some limitations:

Some land cannot grow crops and is useful only for grazing animals.

Humans need enough protein, and many people get it from milk/dairy products.

If population keeps growing, food and farmland may still become insufficient later.
