This is an unscientific joke of a movie. If you compare their "evidence" with the evidence of movies like "What The Health", "Forks over Knives" and "Cowspiracy" - then you will know why this movie and its message is not to be taken seriously. It is a seriously biased piece of propaganda to keep killing animals for food and make people sick and dependent on chemical medication longterm. Because those are billion dollar industries which do everything in their power to not go under. Dont be fooled and be aware of the brainwashing.
