Insect- and herbicide-tolerant GM crops fundamentally reshaped the agricultural landscape in the 1990s. They helped many farmers cut their pesticide use, reduce production costs and greenhouse gas emissions. But these benefits came at a price, namely insects and weeds that began rapidly developing resistance to the chemicals designed to kill them. As the pests evolved, so did the crops and weedkillers engineered to control them. The battle is ongoing, with farmers and scientists plotting their next steps in this arms race.
“[I]t has become possible to directly edit genes and regulatory elements at the molecular level …. which present new risks. Indeed, the annual worldwide threat assessment report of the U.S. intelligence community (2016) added gene editing to its list of ‘weapons of mass destruction.’” So says the Sierra Club of new breeding techniques, including CRISPR-Cas9. The environmental group also has a long history of opposing transgenic (GMO) crops, mostly because they were initially developed as for-profit products by big companies like Monsanto.
Despite this general stance against crop biotechnology, the Sierra Club recently endorsed the planting chestnut trees engineered to survive a deadly pathogen that has all but eliminated the tree from America’s forests. Considering the promise it holds, the Club noted in a recent article, the GM chestnut tree is worth the (mostly hypothetical) risks it poses. Could this signal a change in how environmental groups think about genetic engineering?
