+1! If you want to learn more about this watch Food Inc. available on NetFlix streaming. If you have high blood pressure you may want to skip the part where an Indiana man explains how he was sued by Monsanto for inducing farmers to violate patents by seed cleaning - a practice utilized by farmers for thousands of years.
from what i understand, seed cleaning is part of a process to extract seeds from a harvested crop.
monsanto did not sue that man for cleaning seeds, they sued that guy because he marketed his services to farmers using monsanto seeds, claiming that those farmers could extract seeds from their harvest to avoid buying more monsanto seeds.
however, when you buy seeds from monsanto, you sign an explicit agreement saying that you won't do exactly that. the result of the case was that the court barred the indiana man from cleaning monsanto seeds, not all seeds in general. from what i undestand, they didn't even collect any damages from him, conditioned on him not cleaning monsanto seeds in the future.
Interestingly, this ties in with the music industry. Just as Monsanto "licenses" their seeds, and puts a prohibitive contract with what they can do with it or not, the music industry, DRM, etc.
