the major factors causing environmental pollution are human-generated fossil fuels production and combustion pollutes the air use of pesticides pollutes the soil and water, littering of plastics pollutes the oceans and water bodies, deforestation leads to air pollution etcetera 


there is a global leader to take immediate measures towards restoration and preservation of natural resources before they get damaged up to the point of no return we need to follow all the measures implemented by the government to check harmful effects of pollution

Essay on environmental pollution( 250)



The environment forms a very important aspect of human life as it provides us essentials of life that is air, water, and food but excessive man-made activities like industrialization, construction, and deforestation have led to environmental pollution

the types of environmental pollution are specific to causes and components of the environment environmental pollution is classified into groups depending on the natural components as follows air pollution, noise pollution, soil pollution, and water pollution 


the main pollutants are industries because industries emit harmful gases in the atmosphere which cause air pollution industrial effluents are also discharged into water bodies causing water pollution other pollutants to include smokes from vehicle combustion greenhouse gases emission, for example, carbon dioxide which is high in India 


Air pollution has resulted in harm to human health and destruction of the ozone layers in the atmosphere water pollution has caused the death of aquatic life and acidification, soil pollution has resulted in unhealthy soil that is unbalanced soil pH which does not favor plant growth 


conclusion

Essay on environmental pollution ( 500 words) 


pollution is an undesirable change in the physical and chemical aspects of the atmosphere various types of human activities are responsible for different types of pollution


pollution are different types as follows air pollution, water pollution, noise pollution, and soil pollution 


air pollution: air contains a number of gases but oxygen is one of the most valuable gas for the survival of organisms


 organisms receive oxygen in several forms for example terrestrial organisms receive oxygen from the atmosphere directly through the respiration process 


aquatic organisms will receive dissolved oxygen for their survival air becomes polluted by various several factors 


factors of air pollution emission of gases from industries automobiles and domestic into the atmosphere as follows 


1: carbon oxides co,co2 


 Source: incomplete combustion of fossil fuels transportation industry home heating smoking and CO 2 is an important greenhouse gas 



2: nitrogen oxides- no (nitric oxide) and no2 (nitrogen dioxide)


Source: Motor Vehicles and Industry burning fossil fuels, nitrogen oxides can react with other gases in the atmosphere to form nitric acid hno3 acid rain 



3: sulfur oxides (mainly sulfur dioxide) 


source: combustion of coal oil and electric power generations formation of sulfuric acid h2so4 by reacting with other gases in the atmosphere leads to acid rains 



4:volatile organic compounds 


example: methane,  benzene, propane, and chlorofluorocarbons CFCs 


Source: motor vehicles evaporation from gas tanks industry and various household products 


5:toxic products 


lead and Mercury are considered toxic compounds secreted by human activities 


Source: metal processing waste material incinerators coal combustion accidental spill and mining sakes


6:photochemical oxidant


The ozone layer is depleted (O3) due to mixing with the gases (emitted from Motor Vehicles) and with the sunlight 


Air pollution effects on humans 


air pollutant the respiratory and diseases in humans examples of air pollution-related diseases 


1 carbon monoxide forms carboxyhemoglobin (HbCo) rather than oxyhemoglobin HbO2 which prevents oxygen transfer to body parts 


2. Cardiovascular diseases 


3 severe irritation to eye, ear, nose, and throat 


4 chronic bronchitis 


5 emphysema 


6 cancer 


7 lead absorbed and accumulated in blood, bones, and muscles leads to the following problems.


damages organs kidneys, liver, brain, bones, and reproductive organs behavioral disorders memory problems mood changes and lower IQ in young children, high blood pressure and increased heart disease 


8 mercury absorption leads to mutations and brain disorders like mental retardation etc 


Effects of air pollution on other animals and plants wild and domestic animals probably affected in the same way as humans


Plants damaged by ozone sulfur dioxide and acids ozone weakens pine needles and makes them more susceptible to insects and diseases 


sulfur dioxide surprise growth acid damages leave and also removes nutrients 


control:


1.planting more trees 

2.regular pollution check to your Motor Vehicles 

3.industries have to take proper control measures during the processing of materials 

4.prevent combustion of fossil fuels process leads to co2 concentration not exceeds more than 0.03 percent 

5.create awareness on effects of air pollution 

6.care should be taken while transporting liquid petroleum and diesel etc 

7. use compressed natural gas CNG for public transport 

8. stop using air coolers and refrigerators so it leads to stop emission of chlorofluorocarbons and other harmful gases into the atmosphere.
