Okay, well yes and no. Yes, it could be useful for vegetarians who who are opposed to the idea of killing for food - those who choose vegetarianism morally - but still I'd wager that there'd be a fair few out there who don't agree with the use of stem cells too. In fact I'm pretty sure they're out there already. (Also I know a few vegetarians who are veggie purely because they don't like the taste of meat.) And also it would have the obvious benifits, as mentioned in the article, of less methane and other greenhouse gasses in the atmosphere because of less livestock - I'm not sure on the figures but I heard that cows in particular cause a massive amount of methane that get soaked up in the atmosphere - and of course there would (in thoery) be less factories for processing (live) meat to use up various resources. But, and here's the thing I'm not sure on, how (and this too has already been mentioned) would the flavours vary? There are already dozens of breed of pig for example that have different tastes. Not to mention that there is also the factor of what is going to happen to a). the current livestock and b). the farmers? I live in a rural part of England so I know that the farmers that have been sending their product to the market (throughout generations) depend on selling their livestock for money. The only way I can see this working is if the scientists researching this (assuming they get it right in the end and get the final product as it should be in regards to taste, texture, etc. (and for a cheaper cost?)) work co-operatively with the farmers so that the lab-made meat goes to Burger King (H.J's if you're an Aussie), McDonalds, etc., whereas the "real" meat goes to butchers, supermarkets, local shops etc. and sells for a reansonable price. That way, surely, all the fast food chains out there could still make money using lab meat (chances are it'd still be crap just this time it'd be lab-made crap) and the farmers would still have jobs. The way I see it is the country and the countryside still needs and wants farmers and the people still want "real" meat.
