While the genetic engineering industry maintains that GMO species will not cause problems, the truth is that any damage caused by releasing GMOs into the environment is likely to be irreversible. Because they are alive, GMOs can mutate, multiply, breed with other living organisms, and go on breeding for generations to come. Potentially, the biological pollution from GMOs is far more dangerous than even nuclear or chemical pollution. There is scientific concern and increasing evidence about the risks of releasing GMOs into the environment. Contrary to the claims of the biotech industry, genetic engineering is not a precise science.
Genetic engineers insert genes across species with little understanding of the consequences.
Many of the trials conducted on GMOs have led to unexpected and unwelcome results. A GMO was intended to clean up soil, but unexpectedly led to a build-up in the soil of a highly toxic substance that killed crucial soil fungi, thus diminishing soil fertility. 5 GMOs could cause genetic pollution if foreign genes transfer to related plants. In a University of Chicago study, engineered plants were 20 times more likely to transfer their genes to related species than natural hybrids. Already canola that is resistant to three different chemical weed killers has been found as a problem weed in other fields.
