GMO Wars: The Global Battlefield [View all]

The case against GMOs has strengthened steadily over the last few years. Critics say that genetic engineering disrupts the precise sequence of a food’s genetic code and disturbs the functions of neighboring genes, which can give rise to potentially toxic or allergenic molecules or even alter the nutritional value of food produced. The Bt toxin used in GMO corn, for example, was recently detected in the blood of pregnant women and their babies, with possibly harmful consequences.

A second objection concerns genetic contamination. A GMO crop, once released in the open, reproduces via pollination and interacts genetically with natural varieties of the same crop, producing what is called genetic contamination. According to a study published in Nature, one of the world’s leading scientific journals, Bt corn has contaminated indigenous varieties of corn tested in Oaxaca, Mexico.

Third, a GMO, brought into natural surroundings, may have a toxic or lethal impact on other living things. Thus, it was found that Bt corn destroyed the larvae of the monarch butterfly, raising well grounded fears that many other natural plant and animal life may be impacted in the same way.

Fourth, the benefits of GMOs have been oversold by the companies, like Monsanto and Syngenta, that peddle them. Most genetically engineered crops are either engineered to produce their own pesticide in the form of Bacillus thurengiensis (Bt) or are designed to be resistant to herbicides, so that herbicides can be sprayed in massive quantities to kill pests without harming the crops. It has been shown, however, that insects are fast developing resistance to Bt as well as to herbicides, resulting in even more massive infestation by the new superbugs. No substantial evidence exists that GM crops yield more than conventional crops. What genetically engineered crops definitely do lead to is greater use of pesticide, which is harmful both to humans and the environment.
