The legislation was largely a result
of the «Great Fog» (or «Big Smoke»)
of 1952, an event where higher
levels of coal -
burning due to cold combined with a high pressure weather system resulted in a heavy and toxic cloud that killed an estimated 4,000 people.
According to the Chinese Centre for Disease Control and Prevention, the

level of CO2 to rise.
Chemicals from
burning coal are involved in the creation
of ground -

When
coal is
burned due to combustion that is more or less completed the result is different
levels of energy (B.T.U.'s), and different
levels of air emissions (Sulfur Dioxide - SO2, Mercury - Hg), greenhouse gases (Carbon Dioxide CO2, Nitrogen Oxide - NO3), and amounts
of ash that can potentially be toxic dependent on the conditions within the combustion chamber and ash that can or can not be used in a secondary market (ex.
Scientists say it's apparent that human activity — namely
burning coal, oil and natural gas — has been driving a rapid rise
of carbon dioxide
levels in the atmosphere.
The problem is that we have got enough
coal to
burn for several hundred years, even with a growing world population with higher aspirations, and if we convert all
of that
coal, and therefore
burn it, without capturing the carbon dioxide we would probably be able to raise the carbon dioxide
level ultimately to around 1,500 parts per million.
«The
burning of fossil fuels such as oil, gas and
coal releases greenhouse gases such as carbon dioxide into the Earth's atmosphere, which has warmed to
levels that can not be explained by natural variability, scientists say,» USA Today reports.
However, rising
levels of carbon dioxide emissions from
burning fossil fuels like
coal are contributing to climate change.
In this stylized representation
of the human - intensified greenhouse effect, human activities, predominantly the
burning of fossil fuels (

The former
