AIR POLLUTION
Pollution is the presence o introduction into the environment of a substance that has harmful or poisonous effects on the environment and events.
Air becomes polluted with noxious gases or when black carbon particles are released into the air.
There are 3 main gases that cause air pollution:
- sulfur dioxide
-carbon monoxide
-nitrogen oxides
Sulfur dioxide occurs mainly when palm oil is burned in power plants. This gas is also commonly found in smoke stacks.
Carbon monoxide is caused mainly by gasoline equipment, aircraft and railroads.
Nitrogen oxide causes acid rain.This phenomenon may account for 18% of the worlds GLOBAL WARMING.
CAUSES: Smoke stacks of factories and powerplantsMotor vehicles, cars, buses and aircraftsChemicals, fires and volcanoesFumes from hairspray, paint spray and nuclear weapons
Did you know that nature creates its own pollution too?Volcanoes spew ash into the atmosphere providing a stream of sulfur dioxide.
Forest fires can create industrial smog and release carbon from the trees into the atmosphere.
Effects of air pollution:Global warmingCancer, asthma, respiratory and heart diseasesMelting of our glaciersAcid rain and polluted waterMillions and millions of deaths
Enough! Thats the last straw!Solutions:Ride a bikeAdopt different energy sources(solar, wind energy)Industries should install filters on smoke stacks to purify the harmful gases
