Aswe all know that to live a better life we need neat and clean environment. Pollutionis the mixing of harmful substances into our atmosphere or it can be anycontamination in our environment. Pollution can be in any form like smoke,dust, noise or toxic substances.
Typesof Pollution Mainlythere are four types of pollution – 1. AirPollution – As we all know air is very essential for survival and it is gettingpolluted in many ways. Air pollution occurs when harmful substances are mixedin our environment.
For example, if we talk about our daily life we use our caror truck from home to work that produces smoke from exhaust pipe. We cannotdeny that half of the pollution is created by our vehicles.2. SoilPollution – Soil pollution occurs when toxic substances are dumped or used onsoil. It can be caused by waste disposal, fertilizers or by acid rain. Forexample, we use fertilizers on crop to increase crop yield but on the otherhand it causes soil pollution. All these artificial inputs make soil infertile.
3. WaterPollution – As water is getting polluted day by day, a very small portion ofwater is available for drinking. Water pollution occurs when harmful chemicalsare mixed into water. It can be caused by directly mixing chemicals into thewater bodies. For example, there are many industries that directly dischargetheir chemical waste into lakes or rivers.4. NoisePollution – Noise pollution occurs when we get expose to high level of noise.
It can be caused by noise of heavy equipment’s or by our transportation.Nowadays, the most serious problem of noise pollution is that youngsters liketo listen a very loud music in parties. For example, if we hear the sound level more than 70 decibel canpermanently lose our hearing power. Effects– 1. Environmentaleffects – Pollution affects the environment in several ways. Ozone layer is ashelter from high UV rays but as chlorofluorocarbon gas is increasing day byday in the atmosphere it causes ozone layer depletion. UV rays effect thephysiological and growth of the plant. Greenhouse effect is the major effect bypollution.
Greenhouse effect causes Global warming, climate change, rise in sealevel and many adverse effects on biodiversity. Carbon dioxide, water vapor andmethane are the main gasses of greenhouse. Soil is becoming infertile due touse of pesticides and it also causes food poisoning. Chemicals from factoriesare discharged to water bodies that kills aquatic animals like fish, crab etc.Presence of toxic substance in water is getting unsuitable for crops. Due tothe high pitch of noise many birds migrate from one place to another. Aresearch shows many animal and bird species are disappeared and many are at theedge of extinction.2.
Healtheffects – Ozone layer is a filter for high UV rays but due to depletion ofozone layer these rays cause many skin diseases to humans as well as to animals.The crops grown in polluted soil can cause diseases like fatigue and skinproblems. High level of noise can affect human by permanent loss of hearing.Water pollution causes many diseases like cancer, this is due to the presenceof elements like lead or toxic substances in water. Breathing in polluted aircan cause many respiratory diseases like asthma, cough and cold.Control– Weshould follow three R’s formula, which states to Reduce, Reuse and Recycle. Weshould decrease the use of fertilizers and pesticides on soil. To stop soilpollution government should take strong steps for promoting organic farming andeducate farmers to decrease the use of fertilizers on crop.
To stop airpollution people should use of public transportation, share vehicles withcolleagues and friends. Harmful waste from industries should be treated beforedischarging into waterbodies. Compost should be used at the place offertilizers.
