　　To improve public health is one of the most important functions of modern governments. Each year, governments allocate huge resources to help citizens maintain good health. Among all the measures governments have taken, to solve the problem of environment pollution is regarded by some officials as the most important one. In my mind, among all factors posing a threat to people’s health, environment pollution definitely ranks top and should be addressed timely.

　　To begin with, the air pollution enveloping major cities has caused many diseases among the public. The level of PM2.5 in the air elevates frequently, especially during wintertime. It is inescapable for people to breath in those find particles doing harm to their respiratory system, as they walk on the street or sit in the office. The polluted air also prevents people from doing exercises outdoors, which further weakens people’s immune system. In addition, another invisible killer in the air is ozone during summertime, also called photochemical pollution. The chemical reaction of exhaust emission from automobiles catalyzed by sunlight also harms people’s respiratory system. In a word, the air pollution has become a serious threat on public health and its negative impacts may last for decades. It is high time that governments clean the air that people rely on for existence.

　　Secondly, the population living in seriously contaminated areas is on the rise. Guided by obsolete concepts, government officials of some regions have not realized the significance of sustainable development and purse economic growth at the expense of environment. Factories that fail to meet the standard of environment protection are still working at full strength, by emitting toxic air to the sky and dumping industry wastes to local water system. As a result, the food and water resources of people living near those factories are seriously affected. In the long run, pollutants people absorb in through breathing and daily diets will cause severe diseases, such as cancer. This is happening in too many places. Rich people are able to move to a new place without pollution, but for poor people, they have no choice but suffering from the hurts. To help those people, governments need to enact strict laws to regulate behavior of factories.

　　To sum up, measures should be taken to protect environment, in order to improve people’s health care. At this time, to clean the environment is definitely the issue of top priority that governments ought to address.
