A super-smog in the Chinese city of Harbin has forced schools and highways across the metropolis of 11 million residents to close. Visibility in some parts of the north-eastern city is reported to be as little as 10 metres (32 feet). The density of airborne particles is several times above World Health Organisation recommended limits and it's not the first time the country has faced this problem; earlier this year, air pollution in Beijing also reached hazardous levels. China also faces issues with water pollution. The government has pledged USD $850 billion for a much-needed clean-up of water supplies, but it will be a struggle to reverse decades of water pollution and overuse.
