Today, one of the greatest threats comes from oil. Very often, the discharge
of oil is deliberate. Sometimes, however, it is accidental, as when an oil
tanker is involved in a collision. One of the worst oil tanker mishaps
occurred when the Torrey Canyon ran aground. Thousands of liters of thick
crude oil had to be poured out before she was destroyed by flames. The
effect of this was that a huge oil slick spread over the sea gradually
drifting towards the coast. Great damage was caused to marine life, not only
by the oil itself, but also by the detergents used against it. This disaster
was also untimely. There was a steady stream of sea birds making for the
British breeding grounds. Many of them were alight on the water during the
journey. Their feathers became badly clogged with oil. Thousands of birds
died as a result. Many of them never reached land. How do we go about
controlling or minimizing water pollution ? The task is by no means easy.
Effective pollution control systems depend on policies that combine
technical, economic, social and aesthetic considerations. This means the
role of the Government is all the more important. The Government can combat
water pollution in several ways. One way is to treat waste water to make
water reusable and of high quality. Another measure is to enact and enforce
regulations prohibiting and limiting pollution of waters. Next, adopt new
effective techniques that will prevent or limit the natural runoff of
pollutants, for example, from agricultural areas into streams and rivers. |

Points to include:
* discharge of oil deliberate or
accidental
* elaborate policies from
Government
* enact and enforce regulations
* oil spills -- destroy marine
life and birds
* treat waste water
* adopt new preventive techniques

Today, one of the greatest threats to pollution is oil
discharged accidentally or deliberately. Accidental discharge from oil
tankers like the Torrey Canyon caused oil slick to spread over a wide area.
This together with the detergent used to clear it caused great damage to
marine life. Sea birds crossing the affected area had their feathers clogged
by oil and thousands died. Controlling water pollution requires well-planned
policies from the Government, that encompass various aspects. One way is to
treat waste water to make it reusable and of high quality. Another measure
is to enact and enforce regulations prohibiting or limiting pollution of
waters. Finally, new preventive techniques should be adopted to check
natural runoff of pollutants into rivers. ( 120 words ) |
