In 2000, Chen returned from his studies in Nanjing to his village of Dongshigu in an effort to confront environmental pollution. A paper mill constructed in 1988 had been dumping toxic wastewater into the Meng River, destroying crops and harming wildlife. The chemicals also reportedly caused skin and digestive problems among villagers living downstream from the mill. Chen organized villagers in his hometown and 78 other villages to petition against the mill. The effort was successful, and resulted in the suspension of the paper mill. In addition, Chen contacted the British embassy in Beijing, informing them of the situation and requesting funding for a well to supply clean water to locals. The British government responded by providing £15,000 towards a deep water well, irrigation systems and water pipelines.
