The farmers that we see at the beginning of the trailer are still farming animals for food, but they believe their way of doing it is better for the animals.
The argument here seems to be that producing meat for consumption isn’t inherently bad, but that there are better and worse ways to do it.
However, what might be the most interesting thing about Eating Animals, based on the trailer, is that it doesn’t appear to be a blanket condemnation of eating meat, but rather the particular process of factory farms, which produce meat in mass quantities.
A documentary that’s going to investigate the way that meat makes it from the factory farm to the table is bound to show off some aspects of the process that most of us would probably rather not think about, the sort of thing that might make you consider becoming a vegetarian or vegan yourself if you’re not one already.
