Farmer toilet-trains pigs
A farmer in Taiwan has found a way to keep water cleaner by training his pigs to poo in small litter boxes. From Treehugger.com:
The litter boxes have wire mesh so the urine seeps through, and the fecal matter is vacuumed by a special machine so the area is kept waste-free. The farmer has realized a 50% savings in water use. But possibly even more importantly, the success of his efforts has not only helped him avoid fines for pollution by environmental authorities, but the authorities are encouraging other farmers to follow his lead and start training their own piglets.The farmer, Chang Chung-tou, has been doing this for six years now. The video above is not of one of Chang's pigs, but it's pretty amazing.
