Then, respond to the following: I chose global warming. • What air pollutants combine and contribute to this issue?Carbon dioxide (CO2) and certain other trace gases, including methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), and tropospheric ozone (O3) combine and contribute to this issue (Berg, 2007) • Briefly describe the health and environmental problems caused by the selected atmospheric issue. Some of the observed and potential effects of global warming include changes in precipitation patterns, changes in sea level, effects on agriculture, human health, and effects on organisms. “Global warming will also increase problems for agriculture.
The rise in sea level will inundate some river deltas, which are fertile agricultural lands (Berg, 2007). ”Certain agricultural pests and disease-causing organisms will probably proliferate and reduce crop yields. The increase in the frequency and duration of droughts is a serious problem for countries with limited water resources.
There is data linking climate warming and human health problems. When there are frequent and severe heat waves during summer months it may increase the number of heat-related illnesses and deaths. Climate warming may also affect human health indirectly, such as with the case of mosquitoes.
Mosquitoes and other disease carriers could expand their range into the newly warm areas and spread malaria, dengue fever, and yellow fever (Berg, 2007). According to the World Health Organization, during 1998, the second warmest year on record, the incidence of malaria, Rift Valley fever, and cholera surged in developing countries (Berg, 2007). ” • Provide one key solution to help either reduce the effects or recover from the effects of the selected issue. Carbon dioxide is produced in the greatest quantity and has the largest total effect, so this is one key area we need to focus on to help reduce the effects of global warming.
This can be done by not adding, or cutting back, on the additional greenhouse gas emissions to the atmosphere. References Berg, L. R. , & Hager, M. C. (2007).
