Uncommon Ground

We affect the planet every time we drive our cars, heat our homes or turn on our lights. Many of us look to our forests and oceans to offset our emissions. We can also look ... to uncommon ground. Some farmers in California plant their crops while doing little to disturb the soil. We'll dig into no-till farming, and what they see beneath their feet. And we'll learn how each of us can lead change ... from our own backyards.
