Environmental PollutionPollution means contamination of earth’s environment with materialsthat interfere with human health, the quality of life, or natural functioningof ecosystems (living organisms and their natural surroundings).
Although someenvironmental pollution is a result of natural causes such as volcaniceruptions, yet most is caused by human activities. People are exploiting thenature in many ways and creating pollution everywhere. Mankind today appearslike a foolish man who is wielding. An axe at the branch of the tree on whichhe is sitting.
Many of the analyses in the economic and medical fields havefocused on the negative effect of pollution on absenteeism, fatigue, braindevelopment and cognitive functioning of children. These works suggest strongimpacts of outdoor pollution on the academic performance of children. There aretwo main channels through which pollution can affect the children academicoutcomes. The first one shows how pollution is associated with absenteeism,fatigue and attention problems. Higher pollution exacerbates respiratoryproblems and it generates negative effects on academic performance because ofthe fatigue related to the illness and repeated absenteeism. Environmentalpollutants can at the same time lead to long-lasting health problems onchildren.
A second channel denounces the negative impacts of pollutants onbrain development and behavioral problems.One of the greatest challenges caused by air pollution is GlobalWarming, an increase in earth’s atmosphere due to the buildup of certain gasessuch as carbon dioxide. With the heavy use of the fossil fuels in the modernera, atmospheric concentrations of carbon dioxide have risen dramatically.Carbon dioxide and other gases, known as greenhouse gases, reduce the escape ofheat from the planet and block the radiation coming from the sun The “era”global temperatures are expected to rise because of this greenhouse effect andit would main the earth warmer change climate patterns, affect crop production.Disrupt wildlife distributions and raise the sea level.
Sewage industrial wastes and agriculture chemicals such asfertilizers and pesticides are the main causes of water pollution. Indeveloping nations more than 95 percent of urban sewage is discharged untreatedinto rivers and bays, creating a major health hazard. Water runoff a majorsource of pollution, carries fertilizing chemicals, such as phosphates andnitrates from agricultural fields and yards into lakes, streams and rivers.
Thewater body may then become choked with decaying algae. Which severely depletesthe oxygen supply? It causes the death of fish and other aquatic life. The students are also affected by the environmental contamination.Many of the students suffer a lot due to this. Noise in the environment givesthem unnecessary mental tension which further leads to anxiety, insomnia, highblood pressure and other diseases of this kind. Sound noise also makes themrestless that which causes depression.So the governments of the world should come forward and take stepsagainst this curse so that there might be some affective results in nearfuture.
Some serious steps will certainly ensure the decrease of such kind ofpollution. This is the only way to make a hassle free environment for educationprogress. Unwanted sounds or noise, such as that produced by airplanestraffic or industrial machinery is considered a form of pollution. Noisepollution is at its worst in dense populated areas.
It can cause hearing lossstress high blood pressure sleep loss. Noise pollution can be overcome by adding insulation and soul proofingto doors. Walls and ceilings and also by using air protection. Particularly, ifindustrial working areas.
