Lung Disease

T wo present-day problems of major proportions are not diseases in themselves, but both are detrimental to health. These are smoking and air pollution. The former is a habit that, in some users, can produce as serious results as narcotics or alcohol addiction. Knowledge of air pollution has grown with the increased public awareness of our environment. It is quite clear that there are many serious consequences produced by the products with which we foul our air. Both tobacco and air pollution are controllable: one by individual will, the other by public effort.
