How does Animal Farm tie into real life?

Many people think of animals and only think of what they can do with them to make money, but Animal Farm is a book that explain how animals feel about humans just using them for what they can produce and then farm animals decide to rebel against humans. For example, people look at chickens and think they can get their eggs until they no longer can produce eggs and then they kill the chicken for food, or you get a cow and use it's milk until the cow produces problems or no longer can make milk and then there slaughtered like they did a crime. Therefore this all can tie into reality because even though the animals can't talk and can't rebel against the human race, other people can stand up for animals and say that using the animals like we do isn't right and people need to rather not eat as much meat or not to eat it at all. Vegetarians are one group that would be the people to say that eating animals is not right. Even though humans were created as carnivores, people take advantage of the animals on the planet, and soon the animals will run low and eventually run out.
