GM Food

Genetically modified food is produced from plants which have had their genes tweaked in the lab. Scientists "cut and paste" a gene from another organism into a plant's DNA to give it a new characteristic. This can be to increase yield or to allow the plant to exist in a more hostile environment than normal. Pro-GM scientists say this means cheaper more plentiful food but opponents argue we do not know the consequences of meddling with nature.

Farmers have modified their crops for thousands of years by crossing similar species. However, modern GM is controversial. Critics say the modified crops could "escape" and cross with wild plants with unknown consequences. They also argue that more chemicals are used on some GM fields which may have a negative impact on wildlife. And while no study has found GM food to be harmful to humans, opponents say it is too soon to be sure.

A group of biotechnology experts say it is time to loosen Europe's draconian regulations on genetically modified crops. In a report released today they argue that genetically modified crops have been used safely for decades, so no longer need to be automatically treated as unsafe. They also say that genetically modified crops should be reclaimed from multinational companies and treated as a public good.
