Introduction

Perhaps everyone has ever asked himself a question: «Is my lifestyle healthy?». If you ask 100 people the most popular answer is «No».. Besides health freaks that want to live to be a hundred noone does much to improve their health or at least not to harm it. I must confess that I do nothing about my health.

We need certain things to stay alive and healthy. We need clean air to breathe and pure water to drink. We need also food that safe to eat and housing to shelter us. But we can’t get all these things by ourselves. We live in community, so we can solve our heals problems only working together.

Polluted air is a community problems. Air becomes polluted in many ways. Cars, trucks, busses and airplanes are among the worst polluters. They send partly burned gases into the air. Air can be also polluted by smoke and shows, that the biggest part of them is harmful to nature. And the results of these contacts are illnesses and even deaths.

What is an ecology… .. Ecology is a science, which studies the relationship between all forms of life on our planet and our environment. This word came from the Greek «oikos» which means «home». All living things are related to their environment. The Earth is our common home and we must take care of it.

Since ancient times Nature has provided Man with everything he needed: food to eat, water to drink, wood for building and fuel for heating and cooking. For hundreds of years Man used Nature’s sources and it seemed to people that the resources of Nature had no end. With the industrial revolution our negative influence on Nature began to increase. Big smoky cities with thousands of people, polluting plants and factories can be found nowadays all over the world.

Unfortunately, the idea of thinking about our planet and about the consequences of our activity appeared not so long time ago as it could be. Nowadays scientists from the different parts of the world try to solve ecological problems, but it isn’t enough to do our planet clean. We must protect our home all together, without any exceptions.

This project is devoted to different ecological problems,catastrophes, environmental protection and human health. Can these things be together …..?It summarizes the results of my watching, studing such global problems like «Greenhouse effect»,

«Acid rain»,

«Water pollution»,

«Nuclear energy»,

«Radiation»,

«Nuclear waste»,

«Deforestation».

The purpose of my project is the following: to show actual ecological problems, explain how they change our life and try to find the possible ways to solve them. I suppose that such theme as mine is very actual nowadays and I hope that this information will appeal not only to my mind.

Air pollution

Air pollution is one of the main problems all over the world. Millions of chimneys, buses, cars, plants, factories and other industrial enterprises exhaust fumes and harmful substances into the atmosphere. Poisoned air is the main reason why it is hard to breath in large cities with big amount of plants and transport (example – Nijnii Tagil in the Urals).

Human activity has been increasing the concentration of such gases like carbon dioxide, methane, nitrous oxide and water vapor in the atmosphere. Scientists expect to see a doubling of carbon dioxide over pre-industrial levels around the year 2065.

Every year the atmosphere is polluted by about one thousand (1000) tons of industrial dust. Among industries especially toxic wastes are made by enterprises of colour metallurgy, chemical, petrochemical, black metallurgy, woodworking, pulp paper industry etc. Big cities suffer from smog.

«Leaders» of wastes of harmful substances in an atmosphere in Russia during three last years are Krasnoyarsk region, the Tyumen, Sverdlovsk, Chelyabinsk, Kemerovo area and it is necessary to attribute this areas to a zone of the ecological catastrophe. The most contaminated regions are economic centers of Russian Federation and most populated. Now 2/3 population of Russia continues to live in conditions of dangerous air contamination.

Various chemical elements are intensively absorbed by our organism during breathing, it is harmful for our health. Air pollution is especially harmful for quality of genofond.

Scientists say that air pollution is the cause of acid rains, global warming and of greenhouse effect. I’d like to tell you some facts on this topic.
