Read the following passage and choose the best answer for each question.  

        People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man’s release of new and often artificial substances into the environment or by releasing increased amounts of a natural substance, such as oil from oil tankers into the sea.

      Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only governments, companies, and individuals would make more efforts. In the home, there is an obvious need to control litter and waste.

Advertising has helped this process by persuading many of us not only to buy things we don’t need but also to throw away much of what we have bought. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying, excess use, and careless disposal of the Products we use in our daily lives.

The main cause of pollution mentioned in the passage is ______.
