How to enhance public health is a complex and controversial issue that merits a closer look.While some people claim that medical care should be given priority,others argue that cleaning the environment should take the premier place,since many of the health problems are rooted in the environmental pollution. From perspective, we should attach importance to the quality of surroundings.
In the first place, cleaning the air can improve the public health.In big cities where cars fill the streets, poisonous gas is released every minutes.This might lead to various troubles, including sore throat, chest pains and even lung cancer.In small cities the situation is even worse.Big factories release chemical wastes every moments,which results in diverse diseases.Thus, in order to alleviate health problems caused by air pollution, the best way is to clean the air and use a environmental-friendly fuels instead.
Furthermore,cleaning the water can advance the public health.Since water is indispensable for our daily life,its safety is closely linked to our health.If water source shall be polluted, human health will be gravely destructed.Once, a chemical factory in Minamata, Japan, discharged waste water that contains mercury into the sea.This polluted the fish and shrimps.As a result, local people who ate the fish showed symptoms of poisoning such as muscle weakness,narrowing of sights,etc.The damage to their physical health could eventually lead to death.Hence ,if we deal with such problems in instant,this diseases could be avoided.
Last but not least, reducing noise can improve public health.The point will be illustrated by using an example of mine.My family used to live next to a busy commercial street,which is filled with cars day and night.Not only does car beeping break the peace of the day, but big tracks also spoil the silence of the night.Under such circumstance, I could not devote myself into studying.What is worse, I suffered from nervous problems including sleeping difficulties and depression.So the most efficient way to tackle with my problem is to uproot the causes,such as prohibition of beeping and establishment of soundproof boards along the noisy streets.
To put all in a nutshell, the most valid strategy to enhance our health is to clean the environment. By taking measures to ensure the safety of water sources, to promote cleaner fuels and to eliminate noises in communities,people will enjoy a better life.
