Does everything cause pollution?

This was my first thought when I read “Could Pigs be the Solution to Whey Waste?” Yes, that’s whey as in “little Ms. Muffet sat on her tuffet, eating her curds and whey.” Whey, a derivative of milk, is the liquid that is left behind after the first stages of the cheese-making process. It is also a byproduct of the process used to make Greek yogurt.

Whey is acidic and saturated with bacteria. This makes is it hazardous when released into the environment in large quantities. And with the boom in the Greek yogurt industry large amounts of whey are looking for a final resting place.

Some companies are paying dairy-farmers to use the whey on their farms in cow feed and as fertilizer. Other farmers are using the whey as pig feed. They say the whey is good for the pigs digestion, and the bacteria is also useful, just as it is for humans.

I am glad yogurt producers are finding environmentally sound ways to reuse the whey, but I still wonder, “does everything cause some form of pollution?”
