Precious resource is world’s issue
OPERATIONAL improvements have been adopted most widely in the Western Cape. There is an incorrect perception that the water crisis is restricted to specific regions. In reality, water security is a national and international issue.
According to the US Geological Survey, more than 99.7% of the earth’s water is unusable by humans and most other living things, either because it is saline or trapped in glaciers. This leaves a tiny portion of accessible fresh water for us to use.
Add to this the fact that the world’s population has exploded, and will continue to do so. The World Water Council reports that the human population is on track to grow by 40% to 50% within the next 50 years.
This means that every year, competition for a clean supply of potable water for sustaining life intensifies – so much so, some experts believe, that the next world war will be fought over water.
