Air pollution is a major problem in many places around the world. As cities become more industrialized, air pollution becomes a more important issue. Long-term exposure to air pollution is linked to lung cancer and other adverse health conditions (Pope et al., 2002). The issue is not something new. In decades past, societies struggled with air pollution whenever different methods of transportation and energy were invented. The industrial cities of Britain during the 19th century were mainly polluted due to coal-fired steam engines. Trains and ships were powered by engines that burned coal. As a result of the rapid increase in trade, excessive build-up of air pollution has occurred in some areas of Britain. Coal-fired steam engines constantly emitted pollution into the air. The result was that many people died or suffered adverse health consequences from the pollution. In Linfen there are similarities and differences. Linfen is considered one of the ten most polluted places on the planet. While increased trade has been the main cause of air pollution in Britain, coal mining is a major source of air pollution in Linfen. Many different coal mines are scattered in different parts of Linfen. Furthermore, there are also other sources of pollution. The city has a large population and therefore one of the main sources of emissions are cars. There are also many industrial factories in Linfen. Emissions from both factories and cars contribute to the problem. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

Things like electric cars and solar panels allow people to power their cars and factories without putting too much pollution into the air. However, some alternative energy technologies are still in their early stages. As such, they can be expensive to purchase and implement. If cities want to improve air quality in the long term, they need to create incentives that encourage people to stop using forms of energy that have a negative impact on air quality.
