The word “survive” can be defined as the effort that is made every day to have a more or less “worthy” life. Every human being must depend on food, shelter, medicine, doctors, clothing, work and much more to survive. Pollan argues that not only humans used animals for food. Animals and humans would have to kill creatures to survive. According to the article “An Animal's Place” by Michael Pollan it states that “animals kill each other all the time. Why treat animals more ethically than they treat each other?”(4). Pollan shows that animals need to kill each other to survive; this makes us wonder. In nature animals kill and eat each other; so why should it be wrong for humans? Animals can be useful to humans in many ways. Animal meat can provide us with vitamins, minerals and even nutrients; We also use animals to test products and as our company. Humans need meat because it can provide vitamins, minerals and nutrients. Meat provides large amounts of iron, as well as high-quality proteins. In the article “Should humans eat meat?” by Vaclav Smil, states that “larger brains have benefited from consuming highly qualified proteins in meat-containing diets, and, in turn, hunting and killing animals, butchering carcasses, and sharing meat have inevitably contributed to the evolution of human intelligence in general " (Smil). Smil is demonstrating that this abundance in the diet of animal fats and proteins would allow a progressive development of intelligence.

The empathy we have towards animals can develop with the same feelings and emotions towards humans. The importance is given not only by the amount of proteins they contain, but also by the vitamins, minerals and nutrients. It helps us get energy and stay healthy. More importantly, people need animals to start getting protein and iron at a young age because they gradually begin to successfully develop their brains and become strong. But it also helps prevent different types of diseases.
