August 31, 2012 Wisconsin farmers have learned to do more with less.

From 1960 to 2004, the state's agricultural output grew by an average of 0.72 percent each year, while land inputs dropped by 0.68 percent and labor input dropped by almost 3 percent, according to the USDA.

And while agricultural efficiency is good for keeping cheap food on the shelves, it comes at a cost to the health of local environments and people.

"There's a growing concern in Door County that we're going to have an influx of CAFOs," said Jerry Viste, executive director of the Door County Environmental Council (DCEC).

That's why DCEC invited author David Kirby to speak about Animal Factory, his book about industrial farming on Aug. 22 at the Baileys Harbor Town Hall.
