1. In China motor vehicle use will probably increase substantially over the next several decades as a result of China's rising global economic super power, which already has an enormous environmental footprint.
a. Research the impact of fossil fuels emission from motor vehicles on human health. Summarize your findings.
Fossil fuel emission from motor vehicles as an outdoor air pollution produces pollutants in the air which leads to negative impacts on human health. (Climate Change and Health, 2010). These pollutants mainly include carbon dioxide (CO2) and nitrogen dioxide (NO2). The toxic pollutant nitrogen dioxide is ejected in the air during the process of combustion and it leads to numerous health issues especially on young children. Studies have found that “long-term exposure to NO2” increases the number of children who attracts asthma, furthermore, nitrogen dioxide have also shown to slow down or stop the growth of lungs of young children. (Air Quality and Health, 2011). On the other hand, carbon dioxide have known to affect the climate through trapping heat and energy. Therefore, fossil fuel emission indirectly affects the change of global climates which then leads to health issues.(Risks and Response, 2003). One of these issues is that extreme heat causes thousands of deaths. Secondly, extreme heat causes pollen in air to be more than usual, which could trigger asthma. Furthermore, increased temperature extends to lives of female Anopheles which is a species of mosquitoes that transmits Malaria. (Climate Change and Health, 2012). Therefore, fossil fuel emission directly and indirectly attributes to numerous health issues especially on young children.
b. Based on 300 million motor vehicles, the Chinese would have to dispose of or recycle several hundred million tires per year. Evaluate the environmental impact of tire discard.
