THE CONTRIBUTION OF ATMOSPHERIC POLLUTION TO CLIMATE CHANGE
CHAPTER ONE
INTRODUCTION
BACKGROUND OF THE STUDY
The concept of air pollution is a term that applies to any chemical, physical or biological agent that aects
the natural characteristics of the atmosphere. The atmosphere is a dynamic, natural gas system that supports all life on earth. More than 4.6 million people die every year due to air pollution and most is
attributed to indoor pollution. Indoor air pollution is one of the most overlooked threats to human health, aecting young children who spend an estimated 80% of their time indoors. Studies released in the past few years clearly demonstrates that poor indoor air quality not only increases asthma symptoms but can also be responsible for headaches, fatigue, nausea, allergic reactions, hormone imbalances and liver, kidney or central nervous system damage.
Some people think that outdoor pollution like green house gases and its eects are dangerous but studies have shown that indoor pollutions has the most significant eects.
A recent study conducted by Johns Hopkins` Bloomberg School of Public Health found that in many cases, the level of indoor pollution was five times higher than outdoor and that the presence of these elevated levels of pollution significantly increased asthma symptoms in the children being studied. These findings are all the more alarming paired with the fact that no regulations currently exist for indoor air quality; not in schools, day-care facilities or even in hospitals. Sources of indoor pollution are limitless and some of these sources include: household cleaning agents, pesticides, biological pollutants, building and remodelling materials; to mention but a few.
STATEMENT OF THE PROBLEM
The problems associated with air pollution are continuously on the rise; this is because of the alarming increase in anthropogenic activities that adversely aects the climate and environment and most importantly the health of individuals worldwide. Studies have revealed that the slightest decrease in air pollution can lead to a significant increase in the peoples’ health and increase the life expectancy of individuals world-wide. According to the epidemiology journal; the U.S government and agencies have made significant improvement in reducing the incidence of air pollution and in turn; there has been a decrease in the occurrence of respiratory diseases. However; the burning of fossils, oil spills, natural gas flares and increase in green house gases results in acid rain, cardiovascular and respiratory diseases, depletion of the ozone layer and subsequently global warming. This paper is an investigative approach on the contribution of air pollution on the changes and instability in climate and the disastrous eects of these changes on the health of the general population of human beings in Nigeria. A study conducted by scientists at the Centre for Ecology and Hydrology in Great Britain and published in the BMC Public health Journal has revealed that living with a smoker or in a major city places a person at greater risk of early death than living in the radioactive exclusion zone around Chernobyl. This can clearly tell us that the eects of air pollution on our environment, health and life as a whole cannot be over-emphasized.
