To remain healthy, our bodies must be regulated in a constant state of internal balance, under ever-changing conditions. The term used to describe this process is homoeostasis. Many of the mechanisms involved
in this interplay between ourselves and our environment can be thought of as separate and individual control systems, each with its own specific job to do, and which together form one overall system that is responsible for all our bodily functions.

Scientists think that Antarctica’s continental shelves hold the most promise. In 1973 the U.S. drilling ship Glamor Challenger found quantities of ethane and methane gases, provoking speculation that the southern polar seas contain vast oil fields. The results of seismological surveys of rocks beneath the seabed are encouraging. And although no oil has yet been found, some U.S. experts have predicted a reservoir of 45 billion barrels, almost twice the known reserves in the entire United States.
