A global ban on genetically modified crops would raise food prices and add the equivalent of nearly a billion tons of carbon dioxide to the atmosphere, a study by researchers from Purdue University shows.We must demand that the non-scientific countries that restrict or ban GMOs change their stance, for the sake of the planet! /sarc.
Using a model to assess the economic and environmental value of GMO crops, agricultural economists found that replacing GMO corn, soybeans and cotton with conventionally bred varieties worldwide would cause a 0.27 to 2.2 percent increase in food costs, depending on the region, with poorer countries hit hardest. According to the study, published Oct. 27 in the Journal of Environmental Protection, a ban on GMOs would also trigger negative environmental consequences: The conversion of pastures and forests to cropland – to compensate for conventional crops’ lower productivity – would release substantial amounts of stored carbon to the atmosphere.
Conversely, if countries that already plant GMOs expanded their use of genetically modified crops to match the rate of GMO planting in the United States, global greenhouse gas emissions would fall by the equivalent of 0.2 billion tons of carbon dioxide and would allow 0.8 million hectares of cropland (about 2 million acres) to return to forests and pastures.
“Some of the same groups that want to reduce greenhouse gas emissions also want to ban GMOs. But you can’t have it both ways,” said Wally Tyner, the James and Lois Ackerman Professor of Agricultural Economics. “Planting GMO crops is an effective way for agriculture to lower its carbon footprint.”GMOs have been a source of contention in the United States and abroad, as some believe genetically modified crops pose potential risks to human health and the environment. Three U.S. regulatory agencies – the Department of Agriculture, the Food and Drug Administration and the Environmental Protection Agency – have deemed GMO foods safe to eat, and the United States is the global leader in planting GMO crops and developing agricultural biotechnology.
But in many European and Asian countries, consumer and economic concerns have led to strict regulations on GMO crops, with partial or full bans on their cultivation.
The anti-GMO stance widely held by the left in the United States and Europe is only one of many instances of the anti-science stances of the supposedly pro-science left.
