Buoy C: WATER:
Over 70% of the Earth’s surface is water (and 96% of that is salt water). Fresh Water is a very precious commodity. With global warming and increasing populations, water around the globe is becoming more scarce. Water use for domestic, business, industrial and agricultural purposes will need to change. This has huge political and social implications. Many small communities, towns and cities are built on coasts at sea level and are thus threatened by rises in sea levels. This has implications for sea defences and coastal protection strategies – as we have here every winter in Seaford. Pollution: if we use water, we have to dispose of it. Our rivers and waterways need protecting from hazardous chemicals and agricultural run-off polluting them so that they cannot support life and biodiversity.
