Answer:
The rise of air pollution in Chinese cities is a direct result of the increased economic activity (and very fast economic growth) that globalization has generated.
Explanation:
This is because China, since the 1980s and 1990s, has become a "workshop" for the world: and industrial powerhouse that produces all kinds of manufacturing products for both the Chinese market, and the world market. In fact, China has benefited from the outsourcing of hundreds of thousands of American and European jobs, mainly due to the lower Chinese labor costs.
This increased economic activity, and the consequent higher rise in energy demand, has resulted in serious problems of air pollution in several Chinese cities. For example Beijing, the capital, often has emergency air pollution levels in winter, due to the higher energy demand caused by the use of heating that is mainly powered by coal energy plants.
