The major problems currently facing the worlds water are ocean acidification, pollution, and freshwater scarcity. Ocean acidification is caused by Co2 being absorbed into the ocean, where it dissolves to form carbonic acid. The current volume of Co2 emmited has outstripped the ocean's capacity to neutralise it. This poses a serious threat to many marine species and coral reefs.

Pollution in sea water is becoming so bad that dead zones have appeared in coastal areas, where oxygen levels become so depleted that very little marine life can exist.

Millions of people live in arid or semi arid parts of the world where fresh water supplies are limited, industrial agriculture practices are taking 70% of all freshwater from rivers and lakes. Rising temparatures due to climate change are affecting rates of evaperation causing serious water shortages in some parts of the world.Click on the images to the right to learn more
