Cannibalism: the meat of the matter is...

Scientists have used tissue engineering techniques to create honest-to-goodness edible meat in the lab.

Guardian Unlimited: Researchers have published details in a biotechnology journal describing a new technique which they hailed as the answer to the world's food shortage. Lumps of meat would be cultured in laboratory vats rather than carved from livestock reared on a farm."With a single cell, you could theoretically produce the world's annual meat supply," said Jason Matheny, an agricultural scientist at the University of Maryland.

They're saying vegetarians who gave up eating meat because it was cruel to animals can now return to the dinner table and get stuck into some proper flesh.

"No animals died in order for you to eat this chicken nugget," goes the argument. "So there's no reason for you to stay off the meat now, is there?"

I'm not a vegetarian, but if you follow this logic it means we should be able to enjoy human flesh BBQs some time in the not-too-distant future. No person will have been killed to create the man burgers, so doesn't that remove any kind of moral problem?

You could even donate the cells yourself. And if you're going to go that far, don't be selfish - give the scientists permission to use your cells for mass production and spread yourself around a bit!
