癌症与环境-Cancer and EnvironmentCancer and Environment提纲1．癌症的两个起因。2．造成癌症的环境原因。3．非个人原因造成的环境污染。There are two main causes for cancer: heredity and environment. We can do nothing to change our heredity, that is, the basic physical characteristics that arepassed on to us by our parents. However, we can do a great deal to control our environment, which may account for eighty to ninety percent of all cancers.Enviromnental pollution can be divided into two kinds: personal and impersonal. Personal pollution may be defined roughly as unhealthy habits such as smoking, drinking, and eating the wrong foods. Clearly, with enough will power we can control this personal environment.Impersonal pollution, on the other hand, refers to those things which are beyond our individual control. One example would be indus trial pollution, which is very hard to control because of the expenses that are needed. The American automobile industry, for example, resisted the law requiring smog-control devices because il feared the added expense would reduce profits. Nevertheless, some laws protecting the environment have been quite successful in reducing pollution.
