Pollution refers to adverse alteration of the natural phenomena by human beings, animals or natural disasters which may affect life in one way or another negatively. Pollution is a health hazard that can cause detrimental effects to the natural environment we live in. It occurs in different forms like: Air pollution (atmospheric), land pollution, water pollution, light pollution and noise pollution

Air (atmospheric) pollution

This refers to a situation whereby the atmosphere surrounding us is contaminated by foreign materials of gaseous nature or particulate matter. These particles or gases may be in form of dust, excess carbon-dfioxide, excess sulphur-dioxide, and smoke among many others. All these materials can alter the natural state of atmosphere making it polluted. Dust for instance can cause diseases like asthma and tuber-closis to humans as well a affecting the transportation activities like the volcanic eruptions. A lot of dust in the air makes the rain water that could have been for domestic benefits useless. Diseases like the ones mention above caused by excess dust in the atmosphere makes increases expenses on our budgets and can lead to poverty to many countries in the world.

Excess smoke in the atmosphere can cause choking and some lung problems leading to health complications. Smoke from industries has led to depletion of the ozone layer that shields ultra violet rays from reaching the earth. Ultra violet rays from the sun can cause dangerous diseases like skin cancer to human beings and also affect plants which the primary producers on earth. Gases such as carbon-dioxide and sulphur in excess will not allow the light hits the ground to be reflected back into the atmosphere. This will lead to global warming that has completely altered the way of life on earth at this century. Global warming has caused extreme weather conditions like too much rain leading to floods and also extreme temperatures which have led to desertification. Floods are dangerous to our lives and causes loss of life as it has been witnessed in so many parts of the world. Desertification on the other hand has caused hunger because of lack of rainfall to facilitate plant growth. All these factors are the end results of excess gases in the atmosphere that brings about global warming that causes extreme weather conditions.

Recently a volcanic eruption in Iceland in southern Europe caused major economic losses to so many countries in the world. The eruption paralyzed air transportation which in turn affected many businesses. Tourism activities in and out of Europe were negatively affected because many tourists could not travel.
