Here is another slant on your link.
http://www.globalexchange.org/campaigns/mexico/biodiversity/faq.html
The link talks of genetically engineered corn contaminating existing species of corn in Mexico.
This is a huge problem and one that might be unstoppable. I saw an interview with a woman who farms organic corn in a state where genetic engineering takes place. Wind blew some of the pollen from the genetically engineered corn into her fields, contaminating her crop.
She has lost an enormous amount of money due to the contamination because she can no longer advertise her corn as organic, which was the major selling point.
Lawsuits against huge corporations take years, meaning many small farmers will go out of business before the lawsuits are decided, assuming that there is any chance the decision will be favorable to the small farmer.
Blatham, your second link shows how badly the Shrub needs to be trimmed.
