Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution.
What causes air pollution mean?
The Short Answer: Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.

What is dirty air called?
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog.
How do you know if the air is polluted?
10 Tell-Tale Signs of Air Pollution

Do trees clean the air?
Trees help clean our air.
Global forests removed about one-third of fossil fuel emissions annually from 1990 to 2007. Trees remove pollution from the atmosphere, improving air quality and human health. In Los Angeles, trees remove nearly 2,000 tons of air pollution each year.
How do trees benefit humans in terms of water supply and clean water?
Trees improve water quality by slowing rain as it falls to the Earth, and helping it soak into the soil. They also prevent soil from eroding into our waterways, reduce storm water runoff, and lessen flood damage. They serve as natural filters to protect our streams, rivers and lakes.
What keeps the air clean?
Use low watt bulbs or energy-saving lights. Limit the use of air conditioning units and keep the temperature a few degrees higher. Don’t burn garbage. Avoid using aerosols.
Why should we prevent air pollution?
Reducing pollutants in the air is important for human health and the environment. Poor air quality has harmful effects on human health, particularly the respiratory and cardiovascular systems. Pollutants can also damage plants and buildings, and smoke or haze can reduce visibility.
Where does pollution happen?
mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.
What will happen if pollution stops?
So even if carbon emissions stopped completely right now, as the oceans catch up with the atmosphere, the Earth’s temperature would rise about another 1.1F (0.6C). Scientists refer to this as committed warming. Ice, also responding to increasing heat in the ocean, will continue to melt.
