5. Resistance to diseases and pest
The use of genetically modified organisms that produce Bacillus thuringiensis or Bt as a biological insecticide can significantly reduce the use of far more damaging chemical pesticides, which can both damage the environment and endanger human health. Although Bt isn’t a guaranteed success, as there are several instances of Bt-resistant insects appearing around the world, it does show the potential that GMO has in pest control.
In 2009, the pandemic of late potato blight almost ruined potato and tomato farmers. It is the same fungus that was responsible for the Great Irish Famine in the 19th century. It is estimated that the blight caused some $1.5 billion in damages. Genetically modified organisms that are resistant to this fungus are being developed as we speak and will not only increase plants’ resilience, they will cause a significant reduction in CO2 emissions by reducing the need for fungicide application.
