Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater (the water beneath the Earth’s surface). It is one of the most serious types of pollution.
Water pollution can have many different causes. Factories dump industrial waste into lakes and rivers. Sewage from households is another cause. Farms using pesticides to kill insects and herbicides to kill weeds can also lead to water pollution. These factors cause ‘point source’ pollution while pollutants from storm water and the atmosphere result in ‘non-point source’ pollution.
Water pollution can have dramatic effects.

1.what are point source pollutants?

=> Factories dump industrial waste into lakes and rivers, sewage from households, farms using pesticides to kill insects and herbicides to kill weeds are point source pollutants.

2.what are the non-point source pollution

Water Pollution is the contamination of water bodies. It occurs as a result of introduction of pollutants in water. Water is life. Still, we contribute in polluting the water bodies in several ways.

Water Pollution is mainly caused as a result of improper discharge of household and industrial chemicals wastes into the water bodies.

These dangerous chemicals (in the form of solid, liquid or gases) mixes with water and make it unsafe for living bodies. Water pollutants cause harm to human-beings, animals, trees and other constituents of environment.

Scotland is in the north of Great Britain. It is famous for its rich culture as well as its amazing natural beauty. Visitors to this land can spend endless days exploring its historic centuries-old castles. But be aware – legend says that some of them are haunted by ghosts. Fun-lovers can experience its world-famous festival, the Highland Games where they can enjoy unique Scottish activities such as the piping, drumming, and dancing. They can also see traditional sports, or drink whisky with the local people. Driving through vast green pastures, or boating on scenic lakes – or lochs – are other attractions that Scotland oers.

The great people of this legendary land have also given many of the world’s important inventions like the telephone, the television, penicillin and the raincoat. Edinburgh, the capital, was the first city in the world to have its own fire brigade in 1824. Edinburgh University welcomed the first female medical student in Great Britain in 1869.

* Questions:

1. Is Scotland famous for its rich culture?

2. What might you see while you are exploring a castle?

3. What are some activities you can see at the Scottish Highland Games?

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. But it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.
