Humans have been modifying crops for over ten thousand years. Conventional methods (such as crossbreeding or treating plants with mutagens or radiation) involve large-scale and imprecise changes that are unknown. Using biotech solutions like genetic modification, researchers can make small, precise and extremely well-known changes to crops for the benefit of humans and the environment. GM crops are also much more well-tested than conventional crops to make sure they at least as safe. 1) GMOs decrease dangerous pesticide usage. 2) GMOs increases yield and decrease land use 3) GMOs boost no-tilling farming 4) GMOs save beneficial insects 5) GMOs reduce carbon dioxide emissions.
