Another piece on this new science—though humans have been enhancing their food supply in one way or another for thousands of years—from the Wall Street Journal.
“Right now, the government is deciding whether it's safe for us to eat genetically engineered salmon. The fish, called AquAdvantage, is being developed by a Massachusetts biotech firm and is in every measurable way identical to Atlantic salmon—except it grows to normal size twice as fast. If officials at the Food and Drug Administration (FDA) give it the green light, it would be the first time that a genetically engineered animal is approved for food use.
“Genetic engineering usually conjures up images of Frankenstein. But modern day biotech researchers are anything but mad scientists. Their ground-breaking work has the potential to address world hunger and protect the environment. The AquAdvantage salmon in particular could ease pressure on wild fish stocks, reduce the environmental impact of traditional fish farming, and help feed the growing world population.
“Overfishing and pollution are quickly wiping out the native global fish supply. Already 80% of fish stocks world-wide are fully exploited or overexploited, according to a May 2010 U.N. report. If current trends continue, virtually all fisheries risk running out of commercially viable catches by 2050.
“Fish farming has helped address this problem: About half of seafood consumed world-wide is now farm-raised. But it's expensive. Shipping farm-raised salmon to the United States from Chile, where most of our fish originates, costs as much as 75 cents per pound.
“Faster-growing genetically engineered salmon could help restore America's domestic fish farming industry, trimming costs and reducing energy consumption. If the FDA approves the fish it would also spur investment in other food products. This could help meet the world's growing demand for protein-rich food.
“Through biotechnology, scientists at a firm in South Dakota have developed cattle that are resistant to mad cow disease. Canadian researchers have asked the FDA to approve their "Enviropig," a pig genetically engineered to produce manure that is less polluting. Biotech researchers are also exploring ways to fortify food plants with enhanced nutritional content, which could help alleviate malnutrition and certain diseases in the developing world. And researchers are engineering animals that can better utilize nutrients in feed.”
