It ' s genetically modified to have better flavour and probably to be sweeter . That actually isn ' t true . Most food has been engineered and selective breeding for transport , not sweetness . This is actually something that is just recently coming back where sweet varieties are becoming popular as people are sourcing their food closer . As for the efficiency , that is a good point and should be considered . To my knowledge though , it isn ' t THAT much different in labor . The other issue that I didn ' t bring up is there is Colony Collapse Disorder . This came about around the same time as GMO started doing a new kind of pest control . There is a concern that this is affecting bees , as since this went into effect , bee hives have been dying at roughly 2 x the normal rate . I am part of a bee club the largest bee club in america actually and this is a very real problem they are still trying to figure out . According to wiki , 6 years was 10 million hives lost . We know GMO is messing with the plant biology , and that we know a lot about genetics but not everything . And lastly , as others have pointed out , with GMO you run the risk of mono crops . Each farmer using this great new method is using the same crop . Diseases in a crop or pests can devastate it when you mono crop . So while more efficient , it runs a greater risk . That all said , I like GMO , I support it , but I do think it should be refined . I think we need to address patients on it and what happens when seeds spread . I think we need to support local growers so that we can have more variety and sweet produce species . I think we need to dump more money into researching why the colonies are collapsing . BTW , if bees go away , GMO won ' t matter as we will have to pollinate by hand .
