There is approximately 1,385 billion cubic metres of water on planet Earth, of which only 2.5%, or 35 billion cubic metres, is fresh water.
In 2000, the annual global water usage was approximately 4,430,000 cubic metres, where roughly 2,100,000 cubic metres was used as potable water. With an annual growth rate of approximately 80 million people on Earth, scientists estimate that global water usage will be set to rise to 5,240,000 cubic metres by the year 2025.
