Genetic modification(GM) involves splicing together genes of unrelated species that cannot naturally mix with each other ,and scientists say the applications are almost limitless. The species involved can be vastly different , for example, scorpion toxin or spider venom genes inserted into corn and other crops as a 'natural pesticide'to prevent insects from feeding on them. This is the positive side of the argument. However, not everyone agrees that GM foods will necessarily become the savior for the world's hungry, and people insist that there is no conclusive evidence for the benefits of GM. The whole GM issue creates strong emotions, particularly among the more skeptical opponents of the technology, who have marched across fields and ripped up test plants, demanding that goverments put a stop to "Frankenstein" foods by banning the commercial distribution of GM crops.
