I'd like my meat to bleed and moo.

I found this article from Reuters about making meat in a lab. The motivation behind these efforts argues that this approch would be more eco-friendly and can feed more people.

It's difficult for me to fathom how this can possibly be both eco-friendly and feed more people. I dont have any numbers to back up my argument, but taking into consideration all the technology that must go into a meat-producing laboratory, I'm fairly certain that it is more wasteful than letting the cows roam and eat whatever grass they can find. The amount of humans hours to be put into developing, maintaining, and assuring the quality of these lab-produced meats also calls the method into question.

To think that my next slab juicy steak will come from a petri dish is not that appetizing
Just let my cows roam free and let me eat them as they are.

Dutch try to grow enviro-friendly meat in lab

By Reed Stevenson

UTRECHT, The Netherlands (Reuters) - Dutch researchers are trying to grow pork meat in a laboratory with the goal of feeding millions without the need to raise and slaughter animals.

"We're trying to make meat without having to kill animals," Bernard Roelen, a veterinary science professor at Utrecht University, said in an interview.

Although it is in its early stages, the idea is to replace harvesting meat from livestock with a process that eliminates the need for animal feed, transport, land use and the methane expelled by animals, which all hurt the environment, he said.

"Keeping animals just to eat them is in fact not so good for the environment," said Roelen. "Animals need to grow, and animals produce many things that you do not eat."

Developed nations are expected to consume an average of 43 kg per capita of poultry, beef, pork and other meats this year, an amount that rises around 2 percent annually, data from the United Nations' Food and Agriculture Organisation shows.

Asked whether people would be repulsed by lab-grown meat, Roelen said he believed there would be enough demand, as much of what people eat today is already extensively processed, from the feed that animals consume to the conditions under which they are raised and the preparation of meat after slaughter.

"I can imagine that some people will have problems with it," he said. "People might think it is artificial. But some people might not realize that some part of the meat they eat is artificial."

Research is also under way in the United States, including one experiment funded by U.S. space agency NASA to see whether meat can be grown for astronauts during long space missions.

But it will take years before meat grown in labs and eventually factories reaches supermarket shelves. And so far, Roelen and his team have managed to grow only thin layers of cells that bear no resemblance to pork chops.

Under the process, researchers first isolate muscle stem cells, which have the ability to grow and multiply into muscle cells. Then they stimulate the cells to develop, give them nutrients and exercise them with electric current to build bulk.

After perfecting that process, scientists will then need to figure out how to layer tissues to add more bulk, since meat grown in petri dishes lacks the blood vessels needed to deliver nutrients through thick muscle fibers.

And then there is the question of fat, to add flavor.
