[04:52.28]Pollution means the poisoning of the land, the seas and the air.
[05:00.07]It is one of the greatest problems facing mankind today.
[05:06.08]Industy is to blame for some of the pollution that exists.
[05:12.48]People make the air dirty with machines that produce gases and smoke.
[05:19.27]In cities,thousands of cars give out poisonous gases.
[05:24.57]Badly polluted air can cause sickness and even death.
[05:29.87]Factory wastes containing dangerous chemicals are sometimes poured into rivers.
[05:37.48]Water pollution is serious because we all rely on a supply of pure water to live.
[05:45.97]It is terrible that river pollution can become to so bad
[05:51.97]that fish and plants cannot live.
[05:55.37]We use insecticides to kill insects that attack crops.
[06:01.67]In doing so,we may upset the balance of nature by killing the food supply for birds.
[06:09.16]In some cases,the substances may also harm animals that feed on the crops.
[06:16.95]Everyone wants to stop pollution,
[06:20.45]but it is a difficult problem to solve.
[06:24.44]If people wanted to stop pollution immediately,
[06:28.55]they would have to stop using many of the machines that make life easier for them.
[06:34.84]That is why most people do not want to do that.
[06:40.14]Now,international action is being taken.
[06:45.05]Many governments have already passed some anti-pollution laws.
[06:50.36]There are severe limits on the gases given out from cars.
[06:55.66]Factories are ordered to remove the poison from their wastes
[07:01.15]before sending them into the air or the rivers.
[07:05.64]In some countries,the air has become cleaner,
[07:10.32]and the rivers are beginning to support fish and plant life again.
