ABSTRACT
This chapter discusses the case studies about relationship between oil issues, environmental issues, and chemical issues. The use of large amounts of fossil fuels since the industrial revolution was the main cause of greenhouse gases such as methane and carbon dioxide. A remarkably different type of weather could be observed, which often works against human life. Gases lock up the heat from the sun as a blanket covering the earth and keeps the temperature warm. Methane, nitrous oxide, and carbon dioxide associated with deforestation and burning of fossil fuels are such examples. Generic name for oxidizing materials such as ozone and acetaldehyde, produced by photochemical reactions of atmospheric pollutants nitrogen oxides and volatile organic compounds, in presence of sunlight creating a photochemical smog. Agenda 21 is an environmental conservation action plan for the 21st century.
