Just the opposite — GMO crops can help the environment.
Crops improved through the means of biotechnology save land in two ways. One way is “land sparing” which refers to farmers producing more output per planted acre; and with that, there is reduced pressure to add more farmland in order to keep up with growing food demands. The second way that biotech crops “save land” is more literal. Particularly when farmland is tilled (plowed) for weed control, it is very susceptible to erosion by water or wind.
By growing crops where they are most suitable to grow, farmers can optimize production based on natural systems. Farming sustainably with GMOs means minimal use of fertilizer, pesticides, water and fuel needed to produce a crop or increase yields. Check out our article on myths around biodiversity.
