So what is polluting the air? Every hour, every day, vast quantities of substances are emitted into the air - mostly the result of human activity. These amounts are far beyond the 'absorption' abilityof the air. When a material amount is in the air, damaging flora and fauna on planet - earth - air polluted! **Seven main materials polluting the air : Particles, hydrocarbons and nitrogen oxides Carbon rooms - Two sulfur dioxide - oxide Lead ozone. ** Since we breath 20,000 liters of air every day it can be very dangerous if the air is polluted. Air pollution isn't a new problem even the ancient humans who lived in caves and lit fires caused and suffered from air pollution. Air pollution cantains gases (especially Co2) or particeles, It is caused by nature or mainly by human beings since the society became industrialized and began using machines in factories, cars, trains and all kinds of transportation the problem became bigger and bigger. (Pruduce Electricity) The damges of air pollution is about 2 million people die each year from air pollution. Doctors found out that one of the main damages of pollution is caused to the heart, polluted air increases the blood pressure and this can lead to heart disease and stroke. Others diseases people suffer from are: asthma, cardiopul monary disease and much more! Other than that air pollution also hurts the animals and the plants. What can you do? You can use the public transportation or walking or riding a bike instead of driving in a private car, or you can protest against factories that use machines that pollute the air. If you must use a car buy a hybrid car that has two engines one is regular gas engine and the other one is electrick engine that works on recharge buttary. This engine is usfull for short distance in the city and like this we can reduce pollution.======

In Hebrew -  The air in our atmosphere is composed of different materials: nitrogen, oxygen and other materials, such as organizing carbon dioxide - oxygen. These materials are in a state of gas, colorless and odor. That's why we don't feel the air, usually. In addition to these gases there are also other materials in the air: water vapor, particles of soot and dust, and more.

The atmosphere is like a blanket surrounding the earth and keeps it from changes in extreme temperatures between day and night. During the day, without this blanket, the temperature on earth can reach 120 degrees. Most of our bodies (70%) are made of water. At night, without the atmosphere above us, the temperature on earth can drop to 100 degrees below zero.

==== Many materials are emitted into the air from various sources . Some materials are harmful for the creatures of our planet. Air, even if it looks clear, carries contaminants. When the wind blows, it makes the air and the pollutants thrown into it, move, so that air pollution affects places far from where it was created. ==== 

Air pollution is created from natural processes and as a result of what the person makes in his living area.
