Through genetic modification new proteins are introduced in plant genome which make it naturally resistant to pests and insects.
Fix Nitrogen from Atmosphere
A large amount of fertilizers are used to fix nitrogen in the soil. These chemical fertilizers hurt the soil immensely. GMOs can capture nitrogen directly from atmosphere.
GMO improve nutritional value in fruits
Genetically Modified fruits have added nutrition. For example, a GM tomato can has more antioxidants which help you fight diseases, GM rice has more vitamins etc.
Genetic Modification can make plants resitant to climate change
It opens the possibility of creating plants that are resistant to erratic weather conditions, droughts and floods all of which are adverse effects of climate change.
Actively Combat Climate Change
Genetic modification can increase the carbon capturing capacity of trees. For example: American Chestnut Tree. Although, this can prove unproductive as trees might capture too much carbon which can create an imbalance.
But wait, what exactly are GMOs? and what's all the fuss about DMH-11
