Greenpeace investigates a coal ash disposal site that belongs to the Yuanbaoshan Power Plant, in Chifeng, Inner Mongolia. The disposal site is located in a small valley, which the power plant has divided into more than 10 sections. One by one, each section is filled with coal ash and then covered with earth before crops are planted on the surface. Less than half a kilometer away, there is a dairy collection station for a famous dairy company. On windy days, the coal ash gets scattered far across the earth, blanketing the vegetation. Cows that eat grass contaminated by coal ash will produce less milk by as much as 2kg a day.
