This week on How on Earth, we look at the shale industry, which has transformed this country in ways we could not have imagined a decade ago.    How did this happen?   Where do experts think the fracking industry might be going?     In this two-part series, we consider why Wall Street and environmentalists are becoming strange new allies.

We interview Paula Noonan from Colorado Watch, the platform for tracking Colorado Legislature.   We also listen to excerpts from Bethany McLean, author of Saudi America:   the Truth about Fracking and how it’s Changing the World.

Host/Producer:     Jill Sjong
