One of the worst air pollutants which are affecting our environment today is carbon monoxide, a colourless, odourless gas caused by the incomplete burning of gasoline, oil, and wood. Low concentrations can cause dizziness, fatigue and headaches, while high concentrations can be fatal. Other pollutants such as Carbon Dioxide, Nitrogen and Lead have contributed to the deteriorating environment. We are all guilty of the overuse of same and, consequently, we all contribute to the pollution levels from which we suffer. In the days before the proliferation of large cities and industry, nature's own systems kept the air fairly clean. Wind mixed and dispersed the gases, rain washed the dust and other easily dissolved substances to the ground and plants absorbed carbon dioxide and replaced it with oxygen.
