1970 was “World Conservation Year”. The United Nations wanted everyone to know that the world was in danger. They hoped that the governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1300 different plants, trees and flowers in Holland, but now only 860 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and the water, and everything that grows and lives. We can't live without these things. If we continue like this, we shall destroy ourselves.?

What will happen in the future? Perhaps it is more important to ask “What must we do now?” The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are hoping to save our world. They plant trees, build bridges across rivers in forests and so on. In a small town in the United States a large group of girls cleaned the banks of eleven kilometres of their river. Young people may hear about conservation through a record called “No, One's Going to Change our World. ” It was made by Scatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.?

Death Valley is a land of beautiful yet dangerous extremes. Death Valley can be dangerously cold      during the winter months. Storms in the mountains can produce sudden flooding on the floor of the Valley.
The air temperature during the summer has been as high as fifty- seven degrees Celsius. The sun can heat the ground so that the temperature of the rocks and soil can be as high as seventy -four degrees Celsius.                                                                     
Death Valley contains evidence of several ancient volcanoes that caused huge explosions. Evidence of one of these explosions is called Ubehebe Crater. The explosion left a huge hole in the ground almost a kilometer and a half wide. In many areas of Death Valley it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This movement has created unusual and beautiful rock formations. Some are red. Others are dark brown, gray, yellow or black.
The area was named by a woman in 1849. Thousands of people from other parts of the ountry traveled Lo the gold mining areas in California. They were in a hurry to get there before other people did. One group trying to reach California decided to take a path called the Old Spanish Trail. By December they had reached Death Valley. They did not have to survive the terrible heat of summer, hut there was still an extreme lack of water. There were few plants for their work animals to eat.
The people could not find a pass through the call mountains to the west of the Valley. Slowly, they began co suffer from a lack of food. To survive, they killed their work animals for food and began to walk out of the Valley. As they left, one woman looked back and said, “Good -bye, death valley.”  The name has never been changed.
