Air pollution is a major problem in many regions of the world. As cities become more industrialized, air pollution becomes a bigger problem. Long-term exposure to air pollution is correlated with lung cancer and other negative health problems (Pope et al., 2002). The problem is not new. In recent decades, societies have faced air pollution as new means of transportation and energy were invented. Britain's industrial cities in the 19th century were mainly polluted by coal-fired steam engines. Trains and ships were powered by coal-burning engines. Due to the rapid increase in trade, some areas of Britain have experienced an excessive build-up of air pollution. Coal-fired steam engines constantly released pollution into the air. The result was that many people died or suffered negative 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 was 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, other sources of pollution also exist. The city has a large population, so automobiles are a major source of emissions. There are also many industrial factories in Linfen. Emissions from factories and automobiles contribute to the problem. Say no to plagiarism. Get a tailor-made essay on “Why violent video games should not be banned”? Get the original essay The problem of air pollution is not something that can be easily solved. Things like electric cars and solar panels allow people to power their cars and factories without producing as much pollution in the air. However, some alternative energy technologies are still in their infancy. Their purchase and implementation can therefore be expensive. If cities want to improve air quality in the long term, they need to create incentives that encourage people to abandon the use of forms of energy that negatively impact air quality..
