Okay... can we just go ahead and establish that GMO’s are not retroviruses that effect humans and just clear that misconception out of the gate?

However, corporations that fight against [url=http://www.huffingtonpost.com/2013/02/20/supreme-court-monsanto_n_2720057.html]seed saving[/url] or use genetic methods to prevent the usage of seeds after a single season is unethical, and they should be sacked.
