GM Crops Have not Delivered on Promised Benefits
The Guardian sites two examples of GM crops' failures globally: "In China, where insect-resistant Bt cotton is widely planted, populations of pests that previously posed only minor problems have increased 12-fold since 1997. A 2008 study in the International Journal of Biotechnology found that any benefits of planting Bt cotton have been eroded by the increasing use of pesticides needed to combat them. Additionally, soya growers in Argentina and Brazil have been found to use twice as much herbicide on their GM as they do on conventional crops, and a survey by Navdanya International, in India, showed that pesticide use increased 13-fold since Bt cotton was introduced."
Biotech companies were able to successfully market their GM crops to farmers through a combination of heavy government lobbying, buying up local seed companies, and removing conventional seed from the market. As a result, the three largest GM companies own 70% of the global seed market. Through patenting and intellectual property laws, these companies can legally own and sell their seed for a premium price. As Vandana Shiva, director of the Indian organisation Navdanya International, which co-ordinated the report, so eloquently put it, "Choice is being undermined as food systems are increasingly controlled by giant corporations and as chemical and genetic pollution spread. GM companies have put a noose round the neck of farmers. They are destroying alternatives in the pursuit of profit."
