Air pollution is a major change in the composition of the atmosphere, mainly from smoke, dust, soot, steam or air makes strange gas is not clean, there was a smell coming, reduced visibility, caused climate change, pathogenic for humans and creatures.
Air pollution caused more than 3 million people die prematurely every year, it threatens virtually all of the big city dwellers in the developing countries. According to Fox News 80% of cities in the world can not meet the standards of the World Health Organization on air quality, which is mainly concentrated in poor countries. WHO said the level of urban air pollution worldwide has increased by 8% despite improvements in some areas. This leads to the risk of stroke, heart disease, lung cancer and a variety of respiratory problems.

PARAGRAPH ON AIR POLLUTION
These day, my neighborhood has exposed to air pollution of all kinds, and affected by the harmful effects of the pollutants in the air they breathe. There are many causes of air pollution. One of the causes is vehicular traffic. Smoke generated by factories is also let out into the air. The burning of fossil fuels like coal also leads to harmful smoke.The high levels of air pollution cause respiratory and cardiac problems, and affect other parts of the human body. It also causes other diseases like cancer. Millions of people around the world die each year due to air pollution.

PARAGRAPH ON AIR POLLUTION 2
All terrestrial life forms need air to breathe. We breathe in oxygen from the air and breathe out carbon dioxide. Air pollution is the phenomenon of harmful compounds in the form of gases and fine particles being let into the air thus polluting it.
Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes various diseases, including cancer, affecting other organs of the body.
Vehicular traffic is one of the causes of air pollution. The combustion of the automobile fuel, whether it is diesel or petrol, that powers a vehicle, leads to the release of poisonous gases released through the exhaust of the vehicle. In factories too when production processes are carried out, smoke is generated that is then released into the air leading to pollution. Smoke is also caused due to the burning of fuels like coal. Construction activity also causes air pollution.
PARAGRAPH ON AIR POLLUTION 3
Humans are today exposed to air pollution of all kinds. They are thus affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution. One of the major causes of air pollution is vehicular traffic. Cars, buses, trucks, motorbikes, scooters and rickshaws are run on fuel. Automobile fuel combustion leads to the exhaust of poisonous compounds that include noxious gases as also particulate matter. The harmful gases that are part of exhaust fumes include hydrocarbons, nitrogen oxides, carbon monoxide and sulfur dioxide.
Factories also contribute to air pollution. The poisonous smoke and fumes generated by factories are released into the air thus polluting the air.
Similarly, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke polluting the air. The burning of garbage also creates harmful smoke.
Pollution of the air affects the air that humans and all other life forms breathe. People around the world are suffering from respiratory and cardiac problems, and diseases such as cancer affecting other organs of the body too. Millions of people die each year around the world due to air pollution.
PARAGRAPH ON AIR POLLUTION 4Air pollution refers to the phenomenon of harmful compounds in the form of gases and fine particles being released into the air thus polluting it. If the air is polluted we cannot breathe fresh and clean air. This affects the lives of humans and all other life forms adversely. Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes diseases affecting other organs of the body. It also causes cancer. Millions of people around the world die to air pollution-related diseases each year.
Air pollution is caused by a number of factors. Vehicular traffic is one of the causes of air pollution. When vehicles ply on the roads, the combustion of the automobile fuel, whether it is diesel or petrol, leads to the creation of poisonous gases that are released through the exhausts of the vehicles. These gases, in the form of smoke and fumes, pollute the air severely. Various alternative fuels such as compressed natural gas as automobile fuel are being used now-a-days. Battery operated vehicles are also being run.
Factories also contribute to air pollution in a big way. When various production processes are carried out in factories, they release smoke and fumes. These are then released into the air. We see black smoke emanating from chimneys or exhaust towers of factories.
Smoke is also caused due to the burning of fossil fuels like coal. The burning of farm wastes and other garbage, as also construction activity also lead to air pollution.
PARAGRAPH ON AIR POLLUTION 5
Humans are today exposed to air pollution of all kinds. They are thus affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution.
Vehicular exhausts cause air pollution
One of the major causes of air pollution is vehicular traffic. Vehicles of all kinds have multiplied across the country. Today traffic congestion on roads is very common. During peak and rush hours the traffic snarls are difficult to cope with for motorists and pedestrians. Commuting has therefore become difficult. Vehicles whether they are cars, buses, trucks, motorbikes, scooters or rickshaws are run on fuel. There is a process of fuel combustion that leads to the exhaust of poisonous compounds. It includes noxious gases and particulate matter. The harmful gases include hydrocarbons, nitrogen oxides, carbon monoxide and sulfur dioxide.
There are many causes of air pollution
Factories also contribute to air pollution. The smoke generated by factories is let out into the air thus polluting the air that we breathe. Similarly, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke. Production of electricity is also mostly through the process of burning non-renewable fossil fuels that leave dangerous smoke in the air. The burning of garbage also creates harmful smoke. Construction activity also creates particulate matter that pollutes air.
Air pollution affects us adversely
Today we are witnessing high levels of air pollution that affect the health of man and other creatures. People around the world are suffering from respiratory and cardiac problems, and various other diseases affecting other organs of the body. Air pollution also causes cancer. Millions of people around the world die each year due to air pollution.
The gases that cause air pollution are also greenhouse gases, and have caused global warming and climate change that affect the Earth and its ecology.

Topic 2 : today, more and more schools are polluted by some kinds of emissions in life. So, to reduce the pollution at my school, we should plant a lot of trees to filter the emissions to help our school have a fresh air envirroment
Water pollution has become a continuous increasing problem on the earth which is affecting the human and animal lives in all aspects. Water pollution is the contamination of drinking water by the poisonous pollutants generated by the human activities. The whole water is getting polluted through many sources such as urban runoff, agricultural, industrial, sedimentary, leeching from landfills, animal wastes, and other human activities. All the pollutants are very harmful to the environment. Human population is increasing day by day and thus their needs and competition leading pollution to the top level. We need to follow some drastic changes in our habits to save the earth water as well as continue
