Paul O’Malley Physics 118 Homework #9 1. The article discusses China’s recent increase in coal usage and the amount of developed nations that export coal into China. The importing of coal is mainly due to China’s recent dramatic increase in businesses and overall economic indicators like GDP. The article then goes into talking about how it is hypocritical of the United States and other developed countries to talk about the negative side affects coal has on the environment and then ship it to rapidly developing Nations like China. China went from a country that exports coal to one that imports coal during its rapid economic expansion that occurred within the last 20 years. Since the coal in China is very low grade and filled with impurities, china now has the option to ship in higher grade coal because of their recent economic success. Also, since low grade coal has a worse affect on the environment, China can burn more coal and not exceed limitations.
