I chose this video (http://www.youtube.com/watch?v=4eJs5bqmJ-c) to look into.
Dr. Colin Soskolne talks about what epidemiology is, and what its connections to environmental health are. He begins by defining epidemiology as "a study of diseases as they affect populations" and adds that in addition to diseases, it is also concerned with general social well-being. It is his view that epidemiology has always been important, but emphasizes the re-emerging concern for infectious diseases from the 1980s as one of the reasons it is gaining in importance in recent years.
According to Soskolne, the link between epidemiology and environment is the effect bad quality soil and water, and environment in general, have on the well-being of people, and what can be done about it. He explains that the job of an epidemiologist is to find out how bad the situation is, how badly the environment is effected, and how much time do we have to correct the situation we ourselves have caused.
Soskolne thinks that the problem with our society today is that we do not think far enough. That we are too occupied with today and tomorrow while we should be paying attention to ten or twenty or indeed decades ahead. He says we ought to think about what kind of world we will be leaving for those who come after us. He sees his own role, as well as the role of his colleagues, is to make people see the kind of situation we are in because of the damage done to the environment, and to prevent the worst-case scenario from happening.
