Water is the most common substance found on Earth.

Water is the only substance on Earth which is naturally found in the three states of matter: solid (ice), liquid and gas (water vapour).

Water is a vital aspect of our lives. We use water for many different purposes:

  • Drinking
  • Washing
  • Industry
  • Agriculture
  • Leisure/Recreation

The amount of water on Earth has remained the same since the planet was first formed. This sounds a strange thing to say considering some countries are experiencing droughts and major water shortages.

We expect to turn on the tap and "Hey, presto!" out it comes: clean, clear plentiful water. However, our demand for fresh water has grown over the centuries.

Water influences where people live and how they live. From the earliest time, humans have attempted to control water by building dams and irrigation systems. Water has become an important producer of energy.

Not all human uses are positive. Pollution and mismanagement have threatened the water supply of this planet. Together with this comes the issue of water quality and the safety of tap water. Only in the last twenty years has bottled water become a major profit making concern. We need to ask ourselves why this has happened.

In this new millennium, water will be one of the most important issues facing human society.
