Pig poo into power?

China has an estimated 700 million pigs, producing some two-thirds of the meat consumed there annually.









Pig waste contains a high level of nitrate, which
in liquid form can contaminate ground water and in flake form can
contaminate lakes, posing human health risks.  Of 1.4 million metric tons (1.5 million tons) of pig poo a year  only one tenth  is used now as manure. 



 CRC for Contamination Assessment and Remediation of the Environment (CRC Care), a South Australian-based firm has a possible solution - using a bioreactor called "PooCareTM" and other
technology, the pig manure is converted into biofuel for cooking and
heating while the residual goes to farmers as nutrient-rich fertilizers. Solid waste is converted into a biogas that is then pumped
through gas tanks that can be delivered to the local community. The
entire process takes about a month, with the first biogenerator already
running at a farm in Wuhan, central China.

Rats the Size of House Cats Invade the Florida Keys

A species of invasive African rat larger than the average house cat has made a reappearance in Grassy Key, despite efforts to wipe them out for the past 10 years. According to KeysNet, the population of Gambian pouched rat breed of giant rodents proliferated at the turn of the century when a local exotic animal breeder allowed eight to escape.



As of 2009, the Florida Fish and Wildlife Conservation Commission thought the region was in the clear. But alas, the 3-foot-long beasts, weighing as much as 9 pounds, came back with a vengeance.
