On this week's Moyers & Company (check local listings), biologist, mother and activist Sandra Steingraber explains why she was willing to go to jail for blocking access to the construction of a storage and transportation facility involved in the controversial process of fracking. Steingraber has become internationally known for building awareness about the toxic trespassers she says are contaminating our air, water, and food -- and threatening our children's health. With government captured by the very industries it's supposed to regulate, Steingraber has lost patience with politicians and corporations, but says our kids need to know "mom is on the job" of preventing destruction to the environment.
