Question

Read the following passage and answer the questions that follow:
Pollution is the fouling of the environment - land, water and air- by waste , smoke , chemicals and other
harmful substances. The most serious pollution occurs where there are large cities and many factories
Every industrial country faces the problem of waste. As factories produce new goods for people to buy
,old ones are thrown out with the household rubbish. Burning this refuse pollutes the air , dumping it in
rivers and seas pollutes the water, and rubbish tips are unpleasant and take up much needed space.
Getting rid of plastics is particularly difficult. Wood and paper decay after some time through the action
of bacteria .But plastics never decay. The more we throw away, the more litter is produced.
The world's oceans have been used as 'dust bins', with millions of tonnes of rubbish being dumped into
the seas every year, harming marine life . If too much untreated sewage is poured into seas , lakes, and
rivers from sewers , the water can no longer dilute it. All the oxygen in the water is used up, and the fish
die. The bacteria which normally break down the sewage into harmless substances also die : only
harmful bacteria which do not need air remain, and these cause disease.
