ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by
They were charity hospitals for the poor and sick, as the rich people were treated at home. The early hospitals were dark, crowded and very dirty, so it was very likely to be infected even more, when you went to be cured. The first hospital in Estonia was the hospital of Saint John, first mentioned in 1237. It was for the people who had leprosy. 2.2 Recent developments Many scientific advances have helped to improve patient care. Surgical and intensive care units now use electronic equipment. Modern hospitals are full of advanced equipment such as X-ray machines, ultrasound scanners and life-support machines. Computers help hospitals keep laboratory and medical records. Hospitals use many disposable items for safety such as plastic thermometers, and hypodermic syringes and steel needles. They are used only once, so they cannot spread infection. Scientists have also discovered all kinds of important drugs, such as antibiotics, and certain
cannot limit their scope to mere teaching of abstractions, such as algebra and grammar. They also need to instruct about health, including diet and exercise. Yet sports programs take too much money and time, which otherwise could be used in artistic endeavors, or to buy more computers and books or special tutors. I especially loathe collegiate athletics, which become farm teams for professional clubs. These have no valid role at institutions of higher learning. The whole issue of scholastic competition needs careful review. Presently, space is so limited at many universities, and demand so high, that only students with the highest grades are accepted. Let us expand our ability to enroll students, and aim to admit all qualified applicants. This exclusion of non-A students bothers me more than high tuition rates do. Students in college can work summer jobs, such as fishing off Alaska, to earn their tuition; it is
It is hard to know now what our oceans will look like in the future. Just how damaged they will be by pollution is uncertain. Acid rain The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments.
Topic Health Introduction Good health is very important for us. We should do everything we can to stay healthy. Being in good health means having our body and mind in good working order, free from disease and pain. Ways of keeping health There are many ways for keeping health. To stay healthy we should eat right foot, dress comfortably, spend much time in fresh air, have enough rest, keep ourselves clean and have regular checkups with the doctor and the dentist. A big part of prevention of diseseases is sporting. Poeple need to have phsical exercise. If they can not have it, they will get stressed and they will be infected with dieseases much easier. For example it would be good to run every day for some time. That way one probably will not become fat, he or she will get fresh air and rest from daily problems. There are many other health-sports also. Many people go swimming. During winter people go skiing. Some people also do aerobics. People go to gym as well. Our body need
m. The evening meal is the biggest and the main meal of the day. Very often the whole family eats together. They begin with soup, followed by fish, roast chicken, potatoes and vegetables, fruit and coffee. On Sundays many families have a traditional lunch consisting of roast chicken, lamb or beef with salads, vegetables and gravy. The British enjoy tasting delicious food from other countries, for example, French, Italian, Indian and Chinese food. Modern people are so busy that they do not have a lot of time for cooking themselves. So, the British buy the food at the restaurant and bring it home already prepared to eat. So we can conclude that take-away meals are rather popular among the population. Eating has become rather international in Britain lately. Vocabulary: proverb -- Every cook praises his own broth -- cookery -- variety -- cuisine -- particular -- lunch -- porridge -- rasher -- sausage -- mushroom -- in spite of -- strictly --

Cars also, like factories, produce poisoned gas in the air. So instead of cars, we should use public transport or a bike, in the name of our enviroment. And what about the factories? Well, we can't remove them from the planet, but they should be built in places, where is less forest and no cities near. Water pollution Secondly, water pollution is also a main issue. Many peole throw rubbish in rivers and lakes. Ships at the sea cause oil problems, where oil flows in the water and causes a lot of damage, like killing the sea animals and also birds, who are on the seacoast, where the oil reaches. When these problems continue, soon we won't be able to swim in a clean body of water and the drinking water becomes unusable. In some places there are floods after the snow melts or in autumn, when raining cause sea level rising. When water retreats, it brings
