One of the main ideas that seemed most important to me was that farms can not be sufficient when using a mono-culture. If I were going to review this film, I would focus on the large amounts of information given and how relevant it is to their cause. For example, every time a farmer tried to make their farm specialized for one product they ran into problems, regardless of if it was animals or plants. Nature does not work with just one thing in the same place. Joel Salatin was talking about how humans need to respect the design of nature, I completely agree because the ecosystem anywhere is a fragile system and too much change can have consequences. Russ Kremer found out the hard way that by using large amounts of medication and antibiotics just makes diseases mutate and grow stronger.
One theme that I looked into was about GMO's. I found that most people actually don't seem to know much about GMO's, their opinion on them is based on the media and people telling them organic is always better. Studies have shown that certain GMO's are actually safe to eat and have no effect on your health. For example, Bacillus thuringiensis insecticidal toxin. It is used as a way to keep bugs away and reduce the use of pesticides on crops. It sounds dangerous but a study has shown that it has no effect on your health.( http://www.nature.com/articles/srep01962 ).
