Why is China so dirty?
<|assistant|>
China is so dirty because its air and water pollution are major environmental challenges that are caused by increasing economic development, industrialization and population. Air pollution in China is among the worst in the world, and pollutants are often carried to other countries via wind and air currents. Water pollution in China is a result of industrial waste and agricultural run-off, contaminating sources of drinking water and threatening wildlife habitats. Other contributors to air and water pollution in China include burning of coal for energy and the large number of vehicles on the road. The Chinese government is addressing the problem with regulations and better public awareness, but the challenge is ongoing.
