At the present time the significant changes have been occuring and they are not always positive. Ozone layer protects the earth’s surface from the sun's ultraviolet rays, debilitating the organism's ability to withstand the diseases. It is broken by chlorofluorocarbon, utilizing in aerosol production, in the manufacture of materials for the sterilization of medical equipment and etc. The greenhouse effect and acid rains are the result of burning of the fossil fuels, disposable by different sources. Mass cutting down of forests leads to disruption of the process of rotation the oxygen and carbon in the biosphere. Ecological balance is disrupted also by plenty of disposable garbage and water pollution by harmful substances.
Every year a lot of species of plants and animals have been destroying , forest cover has been exterminating, mineral reserves have been decreasing, the world ocean has been becoming depleted. These losses are incommensurable.
The global environmental crisis may turn into a catastrophe for the planet in the future. If mankind doesn’t change the way of consumption the natural resources, there will begin famine, deficit of clean water and outburst natural disasters. The environmental crisis is overcame by means of ecological education of all stratum of the society, creation of effective nature conservation legislation, implementation the good scientific and technical solutions, applying the conservation ecology.
Hi, today I’ll tell you about the science that measured my whole life. By itself, this is a science about life and people, this science is psychology. It is a very complex but insanely interesting science Whatever article you open, you will find something new for yourself and draw certain conclusions for yourself. Thanks to this science, I learned to understand people, and look at any situation that . happens in my life, on the other hand, and analyze it.Well, such an unexpected science can change everything. As we can see, this is not mathematics, not chemistry, not physics, and TD. I believe that life sciences do not accumulate from the sciences that I have listed.
Many hundreds of years ago, a Native American chief named Shenandoah lived with his people (?) in what is now the state of Virginia. Very little is known about Shenandoah, but the soft sound of his name was given to a river. The Shenandoah River still flows in a deep valley between the mountains in West Virginia, just as it did when Chief Shenandoah lived. There is an old Native American story which tells how the river got its name.
A long time ago, many centuries before Europeans settled in America, there was a great lake of sparkling blue water hidden in the mountains of Virginia. For hundreds of years Native American people lived near this lake, feeding on the fish they caught in its clean waters. The Native Americans often climbed up the mountains and camped there during their long hunts for food. In the evenings they would sit near their camp and look down at the beautiful lake. On a clear, starry night you could see thousands of stars shining and dancing on the water below. The Native Americans loved this lake, and because they could see the stars in it they called the lake, “Clear Daughter of the Stars.” In their language, the word for this was “Shenandoah.”
When Allan got to the airport, the airport official said: “I’m sorry, sir, but your plane has taken off. You will have to take the next flight. You will arrive in New York at about midnight.” Allan was very upset: “I must be in New York at 6pm. I have a job interview there. I can't miss it. It’s the best job in the world. Thousands of men and women dream of such a job.” The airport lady said nothing and turned to another passenger. Allan wanted to ask her about other possible options, but she looked very busy so he stepped aside. Allan didn't know what to do. He realized that he had to call the company manager and tell him that he would not come. For the first time in his life Allan felt really disappointed. There probably wouldn't be a second chance for him. He pulled out his notebook. The time of the interview was written there: 6pm, Tuesday. Allan looked at his digital watch and read: 2pm, Monday.
I live in a little village and feel very happy about it. Although some people may think that life in the country is boring I have many reasons to disagree. First, we enjoy beautiful nature here. There’s a large clear lake near the village and fishermen from the nearby city come every weekend. My friend from the city was really surprised to find out how much fish we have here. He said that most lakes are poisoned nowadays and there's no fish there. It is true that scientific progress does people lots of good but it ruins nature too. If not controlled, it can be dangerous for all of us.
Philip didn’t like autumn. When the teacher told the class about the trip to the country to see the house of a famous writer, he didn’t feel happy at all. Fortunately, it didn’t rain on the day of the trip. When they arrived, they saw a nice wooden house in a large park. In fact, the park was the main attraction of the place. It was very beautiful in autumn with its trees in different colours.
