What is nature

What is nature? It's everything that exists in the world independently of people, such as pants and animals, earth and rocks, and the weather.

Now more and more people are focusing on the nature. It is no doubt that the nature is important to every human being. No nature, no life. Because of the supplies of the nature, we have lived happily for a long time. And we started to gain every thing available from the nature. And this lasted so long a time. Today, people have discovered that the nature around is getting worse and worse.

What is threatening the nature? Air and water pollution, overharvesting of plant and animal species, overpopulation and so on. Overpopulation is the biggest source of pollution. Let's take overpopulation as an example.

What does overpopulation feel like? When we move slowly through the city in a tazi. When we enter a crowded slum district. When the temperature is high and when the air is thick with dust and smoke. The streets are crowded with people. The streets seem alive with people. people eating. people washing. people talking. people

sleeping. people visiting each other, arguing and screaming. people relieving themselves. people pushing their hands through the taxi windows, begging. people leading animals. people, people, people, people. As we drive slowly through the crowd, sounding the taxi's horn, the dust, heat, noise and cooking fires made it like a scene from hell! I admit, frightening.

To the nature, overpopulation is a big problem. More people, more pollution. And the big population is threatening the nature every second.

The rapid rise in world population is not creating problems only for the developing countries. The whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. people in rich countries make the heaviest demands on the world's resources, its food, fuel and land, and cause the most pollution. A baby born in the United States will use in his lifetime 30 times more of the world's resources than a baby born in India. Unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land, food and fuel, and the future will bring poverty, misery and war to us all.

Tribute to the dog

Gentlemen of the Jury:

The best friend a man has in the world may turn against him and become his enemy. His son or daughter that he has reared with loving care may prove ungrateful. Those who are nearest and dearest to us, those whom we trust with our happiness and our good name may become traitors to their faith.

The money that a man has, he may lose. It flies away from him, perhaps when he needs it most. A man's reputation may be sacrificed in a moment of ill-considered action. The people who are prone to fall on their knees to do us honor when success is with us, may be the first to throw the stone of malice when failure settles its cloud upon our heads.

The one absolutely unselfish friend that man can have in this selfish world, the one that never deserts him, the one that never proves ungrateful or treacherous is his dog. A man's dog stands by him in prosperity and in poverty, in health and in sickness. He will sleep on the cold ground, where the wintry winds blow and the snow drives fiercely, if only he may be near his master's side. He will kiss the hand that has no food to offer.

He will lick the wounds and sores that come in encounters with the roughness of the world. He guards the sleep of his pauper master as if he were a prince. When all other friends desert, he remains. When riches take wings, and reputation falls to pieces, he is as constant in his love as the sun in its journey through the heavens.

If fortune drives the master forth, an outcast in the world,
