The study of environment covers the analysis of the surrounding conditions that affect man and other organisms.  Natural and human resources are interdependent and the use or misuse of one affects the other.  Environmental pollution is one threat that both environment and humans face.  Pollution can take many forms.  The air we breathe, the water we drink, the food we eat, the ground where we grow our food, and even the increasing noise we hear every day —all contribute to health problems and a lower quality of life.  A close analysis of damage caused to the environment and the various agents that cause such degradation may help us to ensure quality of life on earth.
