In 1999, biotech boffins in Canada invented the 'Enviropig' genetically transformed to digest grain-based feedstuffs which pigs don't naturally eat, but which are now part-and-parcel of modern intensive pig-rearing .
This piggy-wonder was touted as being cheaper and greener to produce because, thanks to its novel digestive system, it wouldn't excrete huge amounts of polluting phosphates, and wouldn't smell. 'Environmentally-friendly' is always a good PR hand to play.
A hopeful herd of Enviropigs was maintained for 17 years, waiting for the market to want to eat them.
The pigs are all dead now. Total disaster. No customers. All cost and no return.
