An investigative look at the controversial advancements that biotech scientists have made in genetically altering food. A gene from a jellyfish is placed in a potato plant, making it light up whenever it needs watering. Rice plants are genetically transformed to produce vitamin A, preventing millions of African children from going blind. Plants are modified to produce plastic or pharmaceuticals. These are just a few of the touted benefits of genetically modified agricultural -- the use of genetic engineering to alter crops for the benefit of mankind. But while proponents say this new technology has the potential to end world hunger and improve the quality of life of billions of people, others argue that it constitutes the biggest threat to humanity since nuclear energy. Scientists, they claim, are tampering with nature, risking potentially catastrophic and irreversible ecological disaster.
