What means is pollution Pollution is the factors that which are dirty our environment .Now
pollution is a serious problem for human .In jeneral ,pollution can be into 4 types.there are air pollution ,sound pollution ,water pollution and land pollution .1In the 20th century rapid economic development has resulted in environmental problems.Hence,environmental pollution has been a cause for concern for the past few decades.The greenhouse effect caused by the release of carbon dioxide for example has become a main focus in the world.Newspaper headlines,academic material and protests by various environmental activists have forced each one to be aware of their
responsibility towards to environment.There has been an increasing divergence in the views between ecologists and economists whereby the ecologists have a very pessimistic view of the environment in the future,where they believe that the resources are depleting at very fast rate; on the other hand the economists have an optimistic view.Supported by statistical evidence the economic point of view for the future suggests that poverty levels are reducing,the natural resources will last for another 150 years
Amongst the various definitions provided for pollution,one of the defines pollution as,the
release of harmful environmental contaminants,or the substances so release.
The air pollution is caused the smoke from vehicles .The smoke that cames from the facetories
also will pollute the air .Burning rubbish publicly also can produce smoke All he smoke mentioned is poisonous .If we breathe in the smoke ,it can damenge our lung and cause pneumonia .The people who are not responsibility usually throw the rubbish into the river and sea when taking ferry .Prior to analysing the approaches to solving the problem it is essential to understand the harmful effects of pollution.On various fronts it has been argued that environmental pollution results in serious health hazards like increased risk of cancer,skin damage,disrupting the ecological balance and upsetting the climatic equilibrium.Nowadays everything raging from droughts,floods,and earthquakes to the gradual shift in climatic changes,for instance,colder countries expecting abnormally high
temperatures during summers,is being associated with pollution.Theorists have argued that there is little evidence to suggest whether the change in climate will be a good thing or a bad thing.It is the perception that people have or that has been created by media that everyone believes that climatic changes will not be conducive for economic growth.
Gwartney et.al (2000) argue that the need to choose between economic growth and environmental quality may seem obvious when economic activities affect the quality of the air or water.Governments in the developed countries are under pressure from environmentalist to protect the rights of those able to prove that they have been harmed by pollution.
Income growth helps to increase the demand for environmental quality,while technological advances help to lower the cost of reducing both resource use and pollution.Yet incomes above the poverty level and an understanding of the technology are not enough to protect the environment.
The problem posed by pollution can be explained by using the theory of market failure,which
occurs when resources are not efficiently allocated.This theory highlights the problems faced by businesses (producers) who feel that the cost of disposing waste is too high and that profits will be higher if costs are kept to a minimum and disposing of waste through a least cost method is highly efficient.Thus according to the theory of market failures,the true cost to the society is much higher than the private cost of the producer.We must take care of our environment.The cleanliness of our environment is responsibility of everyone.
