SUPER-WEEDS OR MORE FOOD FOR ALL?WHAT are the potential benefits of genetically modified genetically modified
(of an organism) having DNA which has been altered for the purpose of improvement or correction of defects
genetically modified genetic adj [food etc] → crops?
SUPPORTERS claim GM crops could have bigger yields, be more resistent to disease and make farming easier. They would encourage investment in research and development, boosting the economy and creating new jobs.
WHAT are the potential problems?
OPPONENTS say "super-weeds" could be created, which would build up resistence to the herbicides that GM crops resist. Critics also say the sprayed fields will support less and less wildlife. GM plants can also inter-breed with non-GM varieties nearby.
HOW do GM crops work?
MOST GM crops tolerate herbicides. Farmers can spray their crops with weedkillers that will kill all plants in the field except the GM crop. The crop grows stronger because they do not compete with weeds 1. weeds - Refers to development projects or algorithms that have no possible relevance or practical application. Comes from "off in the weeds". Used in phrases like "lexical analysis for microcode is serious weeds."
2. and wildlife for water and nutrients. Another variety of GM crop is modified to produce a toxin toxin, poison produced by living organisms. Toxins are classified as either exotoxins or endotoxins. Exotoxins are a diverse group of soluble proteins released into the surrounding tissue by living bacterial cells. that kills pests that feed on it.
IS there any difference in taste?
BOTH sides agree that GM foods are no different from those produced from regular crops in taste and appearance.
ARE there any health risks to humans?
PRODUCERS say there are no health concerns associated with GM foods. Opponents say insufficient tests have been done and the long-term health impact of GM foods is unknown.
Who makes them?
AMERICAN firm Monsanto produces the majority. The four main crops are soya, maize maize: see corn. , cotton and oilseed rape.
