IntroductionPollution, contamination of Earth’s environmentwith materials that interfere with human health,The quality of life, or the natural functioning ofecosystems (living organisms and their physicalsurroundings). Although some environmentalpollution is a result of natural causes such asvolcanic eruptions, most is caused by human activities.There are two main categories of polluting materials, or pollutants.Biodegradable pollutants are materials, such as sewage, thatrapidly decompose by natural processes. These pollutantsbecome a problem when added to the environment faster thanthey can decompose (see Sewage Disposal). Non bio-degradablepollutants are materials that either do not decompose ordecompose slowly in the natural environment. Oncecontamination occurs, it is difficult or impossible to remove thesepollutants from the environment.

What is Pollution? Introduction of pollutants into the environment which deteriorate the nature and harm living resources and ecosystems thereby endangering human health.
TYP E S O F P O LLU TIO N E N V IR O N M E N T A L P O L L U T IO NAIR N O IS E LIGHTS O ILRADIOACTIVE WATE R THERMAL
SOURCES Smoke from factories Exhaust fumes from motor vehicles like cars, buses, trucks, two-wheelers Power stations & Fertilizer factories Waste gases from factories &houses Smoking
PREVENTIONUsing Battery operated VehiclesSet up Emission control plantsUse pollution control equipment in industriesKeep motor vehicles in good condition to reduce fumesUse bicycles, public transport or electrical vehicleswhenever possible.
SOURCES Waste from factoriesMan-made chemicals used infarming Industrial and household waste Throwing rubbish into rivers,tanks and on beaches.
PREVENTIONDon’t allow waste water and chemicals to flowinto rivers and wellsKeep beaches and watersources cleanSet up Effluent treatment PlantsSTOP throwing things away
SOURCESLoudspeakers, car and bushornsBursting loud fire crackers
PREVENTION Reduce the use of loudspeakers in public places and residential areas Use horns in vehicles sparingly Avoid bursting loud fire crackers especially where there are aged people and small children
SOURCESNuclear power plantsNuclear weaponsTransportationDisposal of nuclear wasteUranium mining
PREVENTION By not using nuclear weapons
SOURCESPower plants creating electricity from fossil fuels Water as a cooling agent in industrial facilities Deforestation of the shoreline Soil erosion
SOURCESHigh intensity Light SourcesLaser beams
PREVENTION Utilizing light sources of minimumintensity is necessary to accomplishthe lights purpose. Turning lights off using atimer or occupancy sensor or manually whennot needed. Improving lighting fixtures, so that they directtheir light more accurately towards where it isneeded, and with less side effects. Adjusting the type of lights used, so that thelight waves emitted are those that are less likelyto cause severe light pollution problems.
