ANTI-POLLUTION NEEDS YOUR EFFORTS
People today are beginning to hear more & more about the problem of pollution. Pollution is caused either by the release of artificial substances into the environment(人造物质的排放),or by increased amounts of natural substances, such as oil, from oil tankers into the sea.
Many people, therefore, see pollution as only part of a larger & more complex problem. Whatever its underlying reasons, it is no doubt that much of the pollution could be controlled if companies, individuals & governments would make more efforts. For instance, there is an obvious need to control litter & waste, which everyone can help to do by cutting out excess consumption & careless disposal of the products we use in our daily lives.
In a word, anti-pollution needs your efforts!
