Food safety advocates may shudder at the thought, but a team of scientists in Canada have come up with a new breed of pig that is intended to make meat a greener, more sustainable food. The Enviropig is engineered to have the same meat quality as your typically breeded Yorkshire pig, with all the ideal protein and fat content developed for the market. But in addition, it is also engineered to produce less toxic manure that releases fewer pollutants into the atmosphere, thereby making it a more environmentally sustainable option for large scale pig farmers.
