University of Toronto Genetically modified (GM) crops are widely used worldwide, but their environmental effects need to be explored more. New research, published in a recent issue of “Science” looks at common genetic modifications in four crops: soybean, corn, cotton, and canola.
Although GM crops can produce more yield and profits, it can lead to changes in agricultural practices that could inadvertently impact the environment. For example, farmers may increase pesticide use as crops become more resistant to herbicides or insect pests.
“Increasing land productivity in the form of greater crop yields can make agricultural land more profitable overall, which can encourage agricultural expansion,”
