  • Balanced presentation - but misses some points (if I may be so bold):
    1 - GM foods are not entirely banned in UK as dairy produce from cattle FED on GM feedstuff is already being sold. So GM is entering the food chain by stealth.
    2 - 'solving world hunger'? Is it? Talk to Dr Vandana Shiva on that one. She is increasingly of the belief GM could lead to a massive food crisis.
    3 - Not much mention of government role in GMO. Corporations and government pose a significant risk of 'skewing' the advertised benefits of GM due to power and deep pockets of available cash.

  • First introduced in 1990 not mutagenesis (exposed to chemicals and radiations) specific and stable
  • Golden rice – rice that contains beta-carotene (Vitamin A), which is not found in regular rice. Bt corn – corn that contains a chemical normally found in a bacterium ( Bacillus thuringiensis ) that is toxic to insects but not to humans. Herbicide resistant plants-eggplant, tobbaco, rice
  • More profit Efficient production
  • Nilwala project area Protection in drought conditions Production in frosty season Survive in flood seasons-this area rice
  • Reduce cost for the chemicals Save money
  • Protect natural resources Save labour costs
  • Development of pest resistant crops Reduced herbicide use is better for the environment and reduces costs for farmers
  • Body become antibiotic resistant
  • human health impacts- allergens, transfer of antibiotic resistance markers, unknown effects For example, inserting genes from a nut into another plant could be dangerous for people who are allergic to nuts environmental impacts-including unintended transfer of transgenes through cross-pollination, unknown effects on other organisms (e.g., soil microbes), and loss of flora and fauna biodiversity Economic-reduced compitition(GM seeds are patented) Suicide seeds-Plants with sterile seeds that are infertile are created Farmers are forced to buy seeds every year
  • Ethics -Violation of natural organisms' intrinsic values Tampering with nature by mixing genes among species Objections to consuming animal genes in plants and vice versa Stress for animal Labeling -Not mandatory in some countries (e.g., United States) Mixing GM crops with non-GM products confounds labeling attempts

    30. 32. <ul><li>we must proceed with concern to avoid causing unintended harm to human health and the environment as a result of our enthusiasm for this powerful technology. </li></ul>
