CultureSome companies are working on changing the structure of plants that are grown as food using new technology called biotechnology or genetic engineering. An example is changing the genes of a type of grain so that it will not be destroyed when farmers use pesticides or herbicides on the crop. There has been a lot of discussion in the media about GMOs (genetically modified organisms). Some scientists, food companies and governments argue that it can help to feed the world's growing population, especially in poor countries. Others argue that genetically modified food may be harmful and that GM crops may affect other crops grown in the same area. Public opposition has led some supermarkets in Britain not to sell food that contains genetically modified ingredients and EU governments have passed laws about labelling so that consumers can know whether the food they buy contains GM ingredients or not.
