III. Main part

1. Conversation on the topic   "Why water should be protected".

The rapid development of industry in the early twentieth century led to significant water pollution. And what we need water?

Water on Earth simultaneously a long and a short. It is a lot in the seas and oceans, but the sea salt water not suitable for drinking as well as for many technical industries and agriculture. Fresh water is significantly less and a third of the population were in acute shortage. The main reserves of fresh water are concentrated in polar ice. Limited supplies of fresh water are reduced even more due to their pollution.

In the last century in addition to natural contamination of natural sources by soil, rocks, minerals, etc. there is a problem of municipal, industrial, agricultural water pollution.

2. The story reading B. A. Ryzhov "Once there was a river."

Once there was a river. At first she was a happy little brook which was hiding among the tall slender fir-trees and white-trunked birches. And everybody said, "how sweet, how pure the water in this Creek!" Then the stream became a river. The water in it flowed not so fast, but was still clear and clean.

The river loved traveling. One day she found herself in the city. Here not growing spruce and birch, but there were huge houses in which people lived. A lot of people. They were glad the river and asked her to stay in the city. River agreed, and it was put in stone Bank. It started going steamers and boats on the shores of sunbathing people. The river watered the entire city.

The years went by. People are used to the River and what did not ask, and did whatever they pleased. Once on its banks he built a huge plant of the pipes which drip filthy streams. Darkened the River of sorrows, became dirty and muddy. Nobody said: "What a pure, beautiful river!" No one walked on its banks. It washed the car, washed linen. And none of the residents did not think that the River is also alive. And she was very worried. "Why are people mean to me? In fact I have them watered, twisted turbine power plants, gave an light, protected on hot days from the heat?" she thought.

As time went on. People are increasingly polluting the River, and she was patient and when they finally come to their senses. Once on the river floated a large tanker, from which the water spilled a lot of oil. The River was covered with black tape, steel its inhabitants - plants and animals suffocate without air. Very sick River.

"No - I think - can't stay with people. Need to get away from them, otherwise I will be dead by the river." She called on the help of its inhabitants. "I was always your home, and now trouble has come, your house was destroyed by the people, and I got sick. Help me to recover, and we will go from here to other places, away from ungrateful people."

Gathered river inhabitants - plants, fish, and snails, and animals - clean your house from dirt, cured of the River. And she ran to the edge of his childhood. There, where there were spruce and birch, where man is a rare guest.

And the residents of the city the next day found that left alone, without a River. Did not light in the homes, factories stopped, the water was gone from the taps ... Nothing to wash, nothing to drink, not soup. Stopped life in the city. Its inhabitants became so dirty that got to know each other. However, it did not matter anyway in the evening there was no light.

Then came the day when the citizens had eaten all their supplies of food. Then the oldest and wisest Citizen said: "Dear compatriots! I know why we lost the River. When I was little, I bathed in its clean water. She was always our friend and helper, and we didn't appreciate it and treated her badly. We unfairly hurt the River and have to ask for her forgiveness. I propose to go to distant lands to pay homage to our nurse. You should apologize to her and promise his friendship. Maybe then she'll come back".

Went the strong and hardy citizens to seek the River. Long sought and found, but not immediately recognized, because it was clean and clear. Asked people the River to get back to the city, and told how bad things are without her, promised his care. The river was kind and did not remember evil. Besides, she began to miss people, which over the years has used in the city.

Returned the River to the city to help its inhabitants. But they have removed all the garbage, cleaned the sewage plant, and even dedicated scientists to monitor the health and well-being of the River. Since then in this city, people and River live together.

And recently, the River was made the honorary citizen of the city, and the Day of her return is celebrated as the main festival.
