Meat is murder? Well, perhaps not for much longer.

A pioneering group of scientists are working to grow real animal protein in the laboratory, which they not only claim is better for animal welfare, but actually healthier, both for people and the planet. It may sound like science fiction, but this technology to create in-vitro meat could be changing global diets within ten years.

"Cultured meat would have a lot of advantages," said Jason Matheny of research group New Harvest. "We could precisely control the amount of fat in meat. We could make ground beef with an ideal fatty acid ratio -- a hamburger that prevents heart attacks instead of causing them."

But it isn't just the possibility of creating designer ground beef with the fat profile of salmon that drives Matheny's work. Meat and livestock farming is also the source of many human diseases, which he claims would be far less common when the product is raised in laboratory conditions.

"We could reduce the risks of diseases like swine flu, avian flu, 'mad cow disease', or contamination from Salmonella," he told CNN. "We could produce meat in sterile conditions that are impossible in conventional animal farms and slaughterhouses. And when we grow only the meat we can eat, it's more efficient. There's no need to grow the whole animal and lose 75 to 95 percent of what we feed it."

 Conventional meat production is also hard on the environment. The contribution of livestock to climate change was recently highlighted by the United Nations' report, "Livestock's Long Shadow", while groups such as Greenpeace and Friends of the Earth have demonstrated how soy farming for animal feed contributes to the destruction of the Amazon.

In this context Matheny believes his project could significantly cut the environmental impact of meat production -- using much less water and producing far fewer greenhouse gases.

"We could reduce the environmental footprint of meat, which currently contributes more to global warming than the entire transportation sector," says Matheny.

Preliminary results from a study by Hanna Tuomisto, at the Wildlife Conservation Research Unit, University of Oxford, suggest that cultured meat would reduce the carbon emissions of meat production by more than 80 percent.
