"Genetic pollution" and collateral damage from GE field crops already have begun to wreak environmental havoc. Wind, rain, birds, bees, and insect pollinators have begun carrying genetically-altered pollen into adjoining fields, polluting the DNA of crops of organic and non-GE farmers. An organic farm in Texas has been contaminated with genetic drift from GE crops on a nearby farm and EU regulators are considering setting an "allowable limit" for genetic contamination of non-GE foods, because they don't believe genetic pollution can be controlled. Because they are alive, gene-altered crops are inherently more unpredictable than chemical pollutants--they can reproduce, migrate, and mutate. Once released, it is virtually impossible to recall genetically engineered organisms back to the laboratory or the field.
