This movie really opened up my eyes to the horrible conditions in which our food and the food of our food is treated. I knew that farms required animals for fertilization and the animals required good farm land to grow big and healthy. However, I wasn't aware that most animals were grown in monocultures. These types of environments don't even sound remotely sanitary, let alone good for the animals. Michael Pollan said himself, "Nature doesn't like monocultures." There's a certain chaos in all of nature that is necessary for the healthy growth of all organisms.
The question comes down to whether or not these are ethical situations. Simply showing the inside of the chicken farm where they were caged in tiny places, beaks cut off, and tossed about already shows that there is something really wrong about it. If an animal isn't happy, it isn't going to be healthy. If it isn't healthy, why would anyone want to eat it?
This movie focuses honestly on the ethics of raising livestock and feeding the population. "As long as it tastes good...As long as it looks good." That's all really people care about. If it's not prepared nicely, then it apparently becomes unworthy of eating entirely. If it tastes delicious, but is packed with preservatives and fatty acids, it's still worth eating. This doesn't make much sense, but happens to be the general consensus when no one gives it a lot of thought. The more thought one puts into it, the more they begin to dislike the idea. Ignorance is truly bliss in the food industry. Like Allen said, "As long as it tastes good."
I have no doubt that the industry doesn't follow the standards most people would expect at the least. People are compensated for not talking about the methods for a reason. If they were all completely ethical and safe for people and respectable, the ingredients and processes wouldn't be so hidden.
There needs to be a change in the industry, but like the movie said, the people are the only ones who can make a change.
