Google has the planet's interest in mind with their pig poo investment. Good idea I think. Here in BC Canada, the Fraser valley has a few spots that the smell could wither you away. Some local hog farms on a hot day let their presence be known for miles. The people that work there must get used to it, or wear masks. http://news.discovery.com/earth/google-invests-in-pig-poo-power-110910.html#mkcpgn=rssnws1 Having those carbon credits is not a bad idea either. They could be worth lots.
It is time the pigs say a big "thank you" to google for saving the humans from obnoxious odor being emitted by the rotting poo of the pigs
I like the social enterprises initiated by Google, they seem to be extremely innovative. Coupled with massive financial and the best brains, theirs seem to be the most likely to benefit society.
