Hopeful is a new film by Jonah Kessel. Xing Long Village in Southern China’s Yunnan Province was once a peaceful farming community. But when a factory dumped 5,000 tons of chromium 6 into a nearby reservoir, cancer rates in the village skyrocketed. The environmental damage and human suffering caused by the illegal disposal of chemicals has been devastating and largely unnoticed. However, an NGO in Beijing 3,000 miles away aims to put responsibility back on the factory.
