New industries bring higher paid jobs and more money but they can also bring pollution. Many of cities in China are amongst the most polluted in the world due to factory smoke or car exhaust fumes.
At the 2008 Beijing Olympics, traffic was banned from the city to ensure the air was clean enough for athletes to compete. Air pollution levels in China's four largest cities currently exceed the World Health Organization's (WHO) safe limits. There are fears over the long-term impact of pollution on the population's health.
Government Minister, Premier Li, said in May 2015 that China must "fight pollution with all its might". Cleaning up the country was to become a priority for China. Several coal-fired power stations which hugely pollute the atmosphere are set to close, billions are to be spent on improving air quality and there is to be a crackdown on polluters.
