Загрязнение воды происходит главным образом, когда люди перегружают водную окружающую среду, ручьи, озера, подземные воды, заливы и моря, отходами или веществами, вредными для живых существ.Вода, необходима для жизни. Все организмы содержат воду, некоторые пьют ее, некоторые живут в ней. Растениям и животным нужна относительно чистая вода, и они не выживут, если в воде будут токсические химикалии или вредные микроорганизмы. Загрязнение воды убивает большое количество рыбы, птиц и других животных, а в некоторых случаях в пострадавших районах убивает все живое.Загрязнение превращает ручьи, озера и прибрежные воды в места, непригодные для отдыха и купания. Рыба и моллюски, пойманные в загрязненной воде, могут быть небезопасны для еды. Люди, которые пьют загрязненную воду, могут заболеть, если они пьют загрязненную воду в течение долгого времени, это может вызвать рак или повредить их будущим детям. Water pollution occurs mostly, when people overload the water environment such as streams, lakes, underground water, bays or seas with wastes or substances harmful to living beings.Water is necessary for life. All organisms contain it, some drink it and some live in it. Plants and animals require water that is moderately pure, and they cannot survive, if water contains toxic chemicals or harmful microorganisms. Water pollution kills large quantity of fish, birds, and other animals, in some cases killing everything in an affected area.Pollution makes streams, lakes, and coastal waters unpleasant to swim in or to have a rest. Fish and shellfish harvested from polluted waters may be unsafe to eat. People who polluted water can become ill, if they drink polluted water for a long time, it may develop cancer or hurt their future children.
I live in a flat on the fifth floor. It is neither big nor small. My flat has three rooms, a kitchen, a bathroom and a corridor.
The sitting room is rather larg., It is light because it has two wide windows. There is a black piano on the left. There is a round table in the middle of the room. The TV set is on the right. There are beautiful pictutes of modern painters on the walls. I like my sitting room and I often spend my free time watching TV there.
My own room is small and very cosy. There are many books on the shelves. My desk is near the window. There is a computer on my desk. To the left there is a sofa with a cushion on it. There is an arm-chair and two chairs in my room.
My parents' room is small. There are two beds, a wardrobe and a dressing table there. We often invite friends and relatives to our place. And everybody feels at home here.
