Chemistry is a very important topic in environmental studies.
Current issues such as the increase in trace greenhouse gases leading to the Greenhouse Effect, depletion of the Ozone layer by CFCs, acid rain and toxic waste pollution all involve some basic chemistry. A general background and knowledge of chemistry will be beneficial in understanding and dealing with environmental problems of the future. An interesting site by the Environmental Protection Agency, explains the effect of manmade CFCs and chlorine emission on the Ozone layer . Also a site by the University of Oregon shows a graphical representation of the decrease in ozone over North America. These sites also give many other interesting links to more information on environmental issues.
