Man and nature project

Man and nature project

Nature has always provided us everything what we need for life. Man has always been dependant on the natural world surrouding him, he needed wood to make a fire or to build a shelter, animals to eat. Later he has needed more and more, land to build a house, to plant crops etc. The evolution has been very fast. Now we advance very fast too. Today is already the past and tomorrow is the future.

The world´s population grew and people needed and wanted more. They did things like clear land to build more houses, use fertilizers to plant more crops, build factories to produce more goods, build power stations to produce more electricity. But it´s very dangerous, the industry and technologies have damaged and destroyed nature. Everything has resulted in changes. Our environment is changing.

Today, the Earth is overcrowded with more than 6 billion inhabitants. All life, not only human life, on our planet depends on three basic elements: air, water and soil. The air we breathe, the water we drink and the soil we plant our foods in are all polluted. Pollution is one of the most serious problems of our era. Our planet is warming more and more from year to year.

There are lot of problems. We produce huge amount of dangerous chemicals that endanger all life, whether plant, animal or human. We have used CFCs (chlorofluorocarbons) in refrigeration, in airconditioning. CFCs can destroy the ozon layer, which protects us from ultraviolet radition, which can cause skin cancer, serious eye damage and blidness etc. We use chemicals, which can get into clouds and make acid rain, which pollutes soil.

All polution is caused by chemical substances getting into our water, soil and air. These chemicals are not just from factories but from products we use daily, things such as laundry detergents used to wash our clothes and pesticides and fertilizers used to grow our food. The cars we use every day produce exhaust fumes which pollute air. Waste and rubbish we produce is either buried, polluting the soil, or burned polluting the air. All these chemicals eventually get into the atmosphere or leak into the soil and pollute our water.

People should begin to protect the Earth and our environment. The danger is very high. The polar icecaps are melting, sea levels are rising, scientist predict that some seaside areas will disappear under the sea in the future. Earthquakes are more frequent, crops and animals are in danger of extinction. We should do something with it , if we want to save our planet and our lives too. Enviromental organisations such as Green Peace or Children of the Earth inform people and try to make them realise the importance of protecting the nature.

We can protect our nature and enviroment by many ways, for example by recycling, using alternative energy, by enviromental organisations, reservations and mainly by enviromental education. Because firstly we have to bring up new generation of young people who will realize that we need to protet our world because it will be damaged soon. 

People should try to use alternative sources of energy. Most of the energy we use today comes from coal, oil and gas. But these will not last for ever, and burning them is slowly harming the atmosphere. Solar power is a way of using the sun´s energy as heat or to make electricity. We can also use wind-power by building modern windmills that spin in the wind. There are several types of water-power. River water in mountains can be used to generate hydroelectric power, and we can also create electricity from sea water

Recycling is the processing of used objects and meterials so that they can be used again. About 60% rubbish from homes and factories contain materials that could be recycled. Recycling saves energy and also reduces damage to the countryside. Glass, paper and aluminium cans all be recycled very easily. Many towns have bottle banks and can banks where people can leave their empty bottles and cans for recycling. A lot of paper bags, writing paper, also newspaper and greetings cards are now produced on recycled paper. 

The spring begins on the 21st March. The weather is clear and sunny but the temperature almost never arise to more then twenty degrees. Nature begins to awake from long winter sleep, nights get shorter and days get longer. Woods and first flowers appear: snowdrops, dandelions, daffodils, forget-menots, violets and many more. ..

June 21st is the date when summer begins. Schoolchildren have two months holidays and lot of people set on journeys and take holidays. The temperature rises to 25 degrees and more, sky is clear and bright, there is a lot of sunshine, no wind blows and sometimes we suffer from a heat, which means the weather is sultry , hot and dry. Summer rains often come in the form of a storm. Then there is a crash of thunder and a flash of lighting and a heavy downpour. Occasionally it starts hailing or there is a cloudburst, but when the storm dies down, a rainbow may appear in the sky.

The fall is usually colder then summer with foggy mornings. It starts on the 23rd September. We can still enjoy a few fine days of Indian summer. Fall used to be the most rainy season and the nature is preparing for the winter, so it´s the time of gathering fruit like apples and pears. The leaves of maples, beeches, birches, oaks and ashes are changing to red, yellow, orange or brown.

After fall usually comes winter, the coldest season of the year. Evething is covered by snow and ice, animals and plants are hibernating, Children enjoy throwing snowballs, sledging, sliding and skating on frozen lakes. The temperature sometimes drops to 20 °C below zero. The hands get numb and stiff, fingers tingle with cold and we sometimes suffer from frostbite. The roads become icy and slipper, which make driving hazardous.
