What's the difference between qualitative research and quantitative research? And what are examples of each?

Pollution is the addition to the ecosystem of someting which has a detrimental effect on it. One of the most important causes of pollution is the high rate of energy usage by modern, growing populations. Different kinds of pollution are found.

In this section we will discuss: 1. Air Pollution. 2.

Water Pollution. 3. Land Pollution.

Examples of Air Pollution: 1. Noise pollution or unwanted sounds that are carried by the air, have an irritating and detrimental effect on humans and other animals. Careful planning of streets and biuldings in towns and better control over noisy vechiles may add to the control of noise pollution.

2. Tobacco smoke is one of the major forms of pollution in buildings. It is not only the smoker who is infected, but everyone who inhales the polluted air.

There is a very strong connection between smoking and lung cancer. Bronchitis is common among smokers and unborn babies of mothers who smoke also suffer from the harmful effects of smoking. 3.

Exhaust Gases of Vehicles:Pollution from exhaust gases of vehicles is reponsible for 60% of all air pollution and in cities up to 80%. There is a large variety of harmful chemicals present in these gases, with lead being one of the most dangerous. 4.

The combustion of caol without special precautions can have serious consequences. If winds do not blow away the poisonous gases, they can have fatal effects and may lead to death. 5.

Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce highly acidic rain, snow, hail, or fog. The acid eats into the stone, brick and metal articles and pollutes water sources. Coal in South Africa is rich in sulphur and the power stations in the Mpumalanga Province could be reponsible for acid rain over other areas of our country.

Examples of Water Pollution: 1. Industrial affluents:Water is discharged from after having been used in production processes. This waste water may contain acids, alkalis, salts, poisons, oils and in some cases harmful bacteria.

2. Mining and Agricultural Wastes:Mines, especially gold and coal mines, are responsible for large quatities of acid water. Agricultural pesticides, fertilisers and herbicides may wash into rivers and stagnant water bodies.

3. Sewage Disposal and Domestic Wastes:Sewage as wel as domestic and farm wastes were often allowed to pollute rivers and dams. Examples of Land Pollution: 1.

Soil pollution is mainly due to chemicals in herbicides (weed killers) and pesticides (poisons which kill insects and other invertebrate pests). Litter is waste material dumped in public places such as streets, parks, picnic areas, at bus stops and near shops.

What do you mean... unless your specific we can't help you... but there is noise pollution, air pollution, water pollution, not sure what else but if this isn't what you want be specific.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
