I've written a load more on synthetically grown meat; the introductory paragraph reads:
Meat in vats, grown in culture from a chemical source derived from animal genetics, will result in meat being grown more like plants than livestock. Such research aims to massively reduce the land and resources used by meat production, increase the safety and nutritional value of meat, stop animal suffering and prevent the further hunting of endangered species for food. It has even been researched by NASA in 2002, as part of an investigation into food production on long-haul space flights. The Economist newspaper in 2006 hailed it as a future industry. Animal farming as an industry is in distress in the modern world, and is criticized for its heavy use of water and inhumane nature. The potential benefits of growing synthetic meats in a sterile and controlled manner are huge.
