Vegetarianism
As the world’s appetite increases, their need for meat also goes up. Meat is the number one source of food, and people have relied on meat since they were created. In fact, “humans derive about twenty percent of their protein from animal-based products” (Vidal). Because people heavily rely on meat, researchers predict there will be a food shortage in the near future. Many believe meat should be cut out of diets for the most part, and the population can be vegans. There are many reasons behind this, and they include: reducing chances of a food crisis, requiring fewer resources, and reducing pollution.
