Airs Sunday, October 19 at 6 p.m. AK-47s, grenades, water? Earth's most precious resource doesn't fire bullets or explode but it is guarded, hoarded, and stolen in a way that ignites political tensions on a local level and an international scale. This month, we travel to Sub Saharan and Pakistan to bring you the stories of those caught up in the struggle to secure clean water. We’ll hear from unapologetic water thieves, reporters turned refugees, and rural residents whose way of life may be completed decimated because of the wording in an old international treaty. Also the voices of American officials, NGO’s, and others.
