Created by - Yash

WHAT IS AIR POLLUTION? Air pollution is the introduction of

particulates, biological molecules, or other harmful materials into Earth's atmosphere, causing diseases, death to humans, damage to other living organisms such as animals and food crops, or the natural or built environment.

Air pollution can result from both human and natural actions. Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity. Pollution from natural occurrences are not very often.

1. Burning of Fossil FuelsSulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles are some of the major cause of air pollution. Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes, ship cause an immense amount of pollution .

CAUSES OF AIR POLLUTION

2. AGRICULTURAL ACTIVITIES

Ammonia is a very common product from agriculture related activities and is one of the most hazardous gases in the atmosphere. Use of insecticides, pesticides and fertilizers in agricultural activities has grown quite a lot.

3. EXHAUST FROM FACTORIES AND INDUSTRIES

Manufacturing industries release large amounts of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air thereby depleting the quality of air.

4. INDOOR AIR POLLUTION

Household cleaning products, painting supplies emit toxic chemicals in the air and cause air pollution.

EFFECTS OF AIR POLLUTION

1. DISEASES

2. EFFECT ON WILDLIFE

Just like humans, animals also face some devastating affects of air pollution. Toxic chemicals present in the air can force wildlife species to move to new places and change their habitats. The toxic pollutants deposited over the surface of the water can also affect animals

3. DEPLETION OF OZONE LAYER

Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays.

Earth’s ozone layer is depleting due to the presence of chlorofluorocarbons, hydro chlorofluorocarbons in the atmosphere

THIS IS HOW OUR WORLD WILL LOOK LIKE IF WE CONTINUE

POLLUTING THE EARTH LIKE WE DO NOW

SMOKE + FOG

=SMOGSmog is a kind of air pollution and it had its origins at the beginning of the 18th century

Smog is harmful for all living beings, but not only.Indeed, cars and factories pollute a lot, although in these years cars pollute much less.

The most polluted Italian city is Milan

Indeed, several times a year "green days” are organized , where you can go around the city center only walking or by bike

Smog causes a smoky dark atmosphere which arises over cities.It decreases visibility, and creates a haze throughout the area
