  2. WHAT IS AIR POLLUTION? Air pollution is a mixture of solid particles and gases in the air. Air pollution is also the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are different types of air pollutants, such as gases, particulates, and biological molecules.

  3. HOW AIR POLLUTION AFFECT THE ENVIRONMENT? • Air pollution can harm us when it accumulates in the air in high enough concentrations. Millions of Americans live in areas where urban smog, particle pollution, and toxic pollutants pose serious health concerns. People exposed to high enough levels of certain air pollutants may experience: • Irritation of the eyes, nose, and throat • Wheezing, coughing, chest tightness, and breathing difficulties • Worsening of existing lung and heart problems, such as asthma • Increased risk of heart attack

  4. WHAT CAUSE AIR POLLUTION? 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.

  5. HOW AIR GETS POLLUTED The fossil fuels, firewood, and other things that we burn produce oxides of carbons which got released into the atmosphere. Earlier there happens to be a large number of trees which can easily filter the air we breathe in. But with the increase in demand for land, the people started cutting down of trees which caused deforestation. That ultimately reduced the filtering capacity of the tree. Moreover, during the last few decades, the numbers of fossil fuel burning vehicle increased rapidly which increased the number of pollutants in air.

  6. Ways To Reduce Air Pollution • Reforestation- The quality of air can be improved by planting more and more trees as they clean and filter the air. • Policy for industries- Strict policy for industries related to the filter of gases should be introduced in the countries. So, we can minimize the toxins released from factories. • Riding a bike or walking instead of driving. • Taking a bus or carpooling. • Buying a car that has greater fuel efficiency. • Turning off lights and appliances when they are not in use.
