 resistant to disease, drought, salt ( need less water or color change when need of water) crops that become tolerant to salt =more crop production in harsher environment Food will be 
 more nutritious, longer shelf life (more balance diet with limited foods, prevention of food spoilage money saver longer life more money longer going bad time) Expand the capacity of Agriculture e.g. to produce medicine (grow it out In the field and/or get animals to do it) ex. Mago tree in chirnadad will become healing tree Agriculture will be environmentally friendly ess irrigation, pesticides, herbicides etc. ( if we reduce all this we can produce evi friendly environment) The New “green Rev: GMOs Monsanto Seeks big Increase In crop Yeilds -Monsanto the leader in agric. Biotechnology, pledge Wednesday to dev seed that would double the yield of crops….. The Reality Pesticide and herbicide resistant crops Approx. 60 -70% of the Soy, Cotton, Canola, Corn, Potatoes in N.
