Monsanto: “roundup ready” GMO corn and soybeans Roundup Glyphosate herbicide can be sprayed on crops Weeds that are not GMO are killed Concern that glyphosate-resistant weeds are selected Farmer must buy the pesticide along with patented seeds Is the pesticide safe for people and wildlife? Much less toxic to CNS than other organophosphates (often used as insecticides), but other ingredients in Roundup are toxic Glyphosphate is the 3rd leading cause of agricultural worker iIlness in California and the leading cause of complaints in the UK. http://www.for-wild.org/download/roundupmyth/roundupmyth.html Genetic Engineering of Herbicide Tolerance

Dangers of GMO’s • Reduction of diversity • High biomass GMO’s crowd out natural varieties • A few companies control patents on genetic makeup of commercially used plants • Some people are allergic to protein products of foreign genes transferred into food crops • Transfer of exotic genes from energy and “pharmacrops” to human food supply can occur • Crops raised outdoors release pollen that fertilizes non-GMO plants – StarLink corn: approved for animal consumption but found in totrtilla chips – Liberty Link rice: herbicide resistant strain contaminated other rice – American crops have been banned in European markets

The ProdiGene Fiasco (2001) • GMO corn produced trypsin (digestive enzyme) and pig vaccine • “volunteer” GMO corn found growing in the same Nebraska field, planted with soybeans, next year • Similar violation the following year in Iowa • USDA penalties: – Fine of $250,000 – Charged $2.8 million to buy and destroy 500,000 bushels of contaminated soybeans – Required to clean storage facility – Required to pay $1million bond and institute employee education program • Ordered to destroy 155 acres of corn due to risk of pollen contamination • Similar prior incident with StarLink Cry9C corn • Several organizations - Sierra Club, UCS, etc. - question effectiveness of USDA inspection service (APHIS) in enforcing existing laws

August 10, 2006: Judge Rules against USDA for Permitting Biotech Firms to Grow Experimental Drug-Producing Crops in Hawaii Federal Judge J. Michael Seabright rules that the US Department of Agriculture violated both the Endangered Species Act and the National Environmental Policy Act when it allowed the cultivation of drug-producing GM crops in Hawaii. The court says the USDA acted in “utter disregard” of the two laws because it failed even to conduct preliminary investigations before granting approval for the growing of these crops. The Hawaii islands are home to 329 endangered and threatened species. Seabright’s ruling is the first court decision regarding plants that have been genetically modified to produce pharmaceutical drugs or industrial compounds. The case primarily concerned four permits that had been issued to Monsanto, ProdiGene, Garst Seed Company, and the Hawaii
