ABSTRACT
We don’t usually think about the air we breathe, the water we drink, or the earth on which we trod and till to grow the food we eat. It is in fact quite natural to take all these most basic elements for granted—that is, until they are taken away from us through naturally occurring or man-made pollution and contamination. It is then, and perhaps only then, that we begin to truly appreciate the elemental building blocks of nature.
