Why is China so dirty?
<|assistant|>
China is so polluted because its economy is highly reliant on coal, which is one of the most polluting types of fuel, and many of its cities lack the infrastructure and policies to adequately capture and process air pollution. Furthermore, China has experienced rapid industrial and economic growth over the last few decades, resulting in more air and water pollution.
