Genetically modified (GM) crops do not help increase the production level and therefore are not an effective solution to check inflation that has been triggered by demand-supply mismatch, according to experts. ”There is no concrete evidence that GM crops increase production. They only control insects, which can well be done by some other organic methods,” Kerala Biodiversity board chairman VS Vijayan said. Speaking at a meeting on biotechnology and biosafety here on Wednesday, Mr Vijayan said apart from having health hazards, the GM seeds are also expensive.
