高三英语作文 疾病控制
Environmental 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.

Nevertheless, some laws protecting the environment have been quite successful in reducing pollution.
