I don't think we have yet perfected growing meat in a lab (some specific organs, yes; but not meat in general).I can see many advantages to industrially grown meat, not least issues of hygiene and of quality control (every piece of meat will be just like the piece before, which at least will make life easier for supermarkets, which love consistency of product).The problems as I see it are: Maybe not so much a problem for the consumer, but it won't help the animals; because if there is no commercial incentives for farming domestic animals, then the population of these animals will fall dramatically (they may not be being killed, but neither will they be born), and they may only really be found in zoos (and may breeds will probably die out altogether). Even if we can grow the flesh of the animal, can we be sure that the flesh contains all of the nutrients that we presently take from meat (we do not even know what all the various nutrients are, so how can we be sure that they all remain).Ofcourse, their are other environmental impacts (mostly what environmentalists would regard as benefits): Large amounts of methane are produced by ruminants, and if sheep and cattle are brought to the brink of extinction (existing only in zoos) it will significantly reduce the amount of methane being produced. Methane is classed as a greenhouse gas that is more potent than CO2. Sheep and cattle require substantial areas of grassland. If sheep and cattle are removed from the landscape, much of that grassland would naturally return to forest (ofcourse, it may be that we actually reallocate that land for other purposes - e.g. for the production of biofuels, and so we will not then allow the land to reforest).
Quorn was a brand name in the UK for a range of soya-based, meat-substitute ready-meals.I tried a couple (in the name of research, of course) & although the chicken 1 tasted vaguely chickenish, it was dry & flaky - the texture was totally wrong. As for the beef - YUK!
