In the U.S., one pork factory farm can house more the 500,000 pigs. They produce more waste per year then the residence of Manhattan. The unregulated wastes causes massive damage to ground water.
What better way to control the waste then to potty train them pigs.
“Taiwan’s 6.5 million pigs are a source of river pollution. But one Taiwanese farmer has found that potty training is porkers goes a long way in both conserving water and keeping it clean. He’s trained his hogs to use a litter box, and has had such great results that he’s starting to advocate the practice to other farmers.” – from treehugger.com
Will it does cut down on waste? Yes, but it still needs to be deposed of somewhere. Shit in = shit out.
