Air Pollution

Air pollution is when unwanted chemicals, gasses, and particles enter the air and the atmosphere causing harm to humans, animals and all the nature.

Causes of Air pollution are divided into two categories

Some sources of air pollution come from nature. These include eruptions of volcanoes, dust storms, and forest fires.

Human activity is a major cause of air pollution, especially in large cities. Human air pollution is caused by things such as factories, power plants, cars, airplanes, and methane gas. New year is coming, everyone is exploding fireworks and crackers, those mentioned are very bad for air.

One of the major ways that humans cause the most air pollution is by burning fossil fuels. Fossil fuels include coal, oil, and natural gas. When we burn fossil fuels this releases all sorts of gasses into the air causing air pollution.

Air pollution has a huge effect on the envoirnment those are :

Global waming - One type of air pollution is the addition of carbon dioxide gas into the air. Some scientists believe that releasing too much carbon dioxide into the atmosphere is one of the causes of global warming. This upsets the balance of the carbon cycle.

The ozone layer - The ozone layer helps protect us from harmful rays from the sun. It is getting damaged from air pollution such as methane gas from livestock and CFCs from spray cans.

Acid Rain - Acid rain is created when gasses such as sulfur dioxide get high into the atmosphere. The wind can blow these gasses for miles and then they get washed out of the air when it rains. This rain is called acid rain and can damage forests and kill fish.

Not only envoirnment but it also has huge effect on health. Air pollution can also make people sick. It can make it difficult to breathe and cause diseases such as lung cancer, respiratory infections, and heart disease. According to the World Health Organization, 2.4 million people die each year from air pollution. 

Air Quality Index

The Air Quality Index is a way for the government to alert people to the quality of the air and how bad the air pollution is in an area or city. They use colors to help you determine if you should go outside. 

Here are some examples : 

-Green - the air is good. 

-Yellow - the air is moderate 

-Orange - the air is unhealthy for sensitive people like the elderly,children,  and those with lung diseases. 

-Red - Unhealthy Purple - Very unhealthy 

-Maroon - Hazardous

To wrap up our blog here are some facts about air pollution 

-A thick smog formed in London during the late 1800s. It was called the London Fog or the Pea Soup Fog. 

-The biggest single air polluter is road transport such as cars. 

-Air pollution in the United States has improved since the introduction of the Clean Air Act. 

-The city with the worst air pollution in the United States is Los Angeles. ---Air pollution can cause your eyes to burn and make it difficult to breathe. Indoor air pollution can be much worse than the pollution outdoors.

What can we do to help?

Anytime you can use less energy, like electricity or gasoline, it can help reduce air pollution. You can help by turning off the lights when leaving your room and not leaving the TV or computer on when you're not using it. Driving less helps a lot too. 

Dictionary :
