We can’t live without water, and thankfully much of the Earth is made up of it. Yet we face major problems where the life-sustaining liquid is concerned. While there is technically enough freshwater available for all 7 billion of us, 20% of the world’s population live where there is physical water scarcity. Vast improvements in infrastructure are required in order provide freshwater to areas which remain without, but also to ensure continued access in the face of widespread pollution, wastage and drought.

The degradation of water quality not only poses supply problems for our population, but also has a huge, inevitable impact on marine life. Whether it’s through storm water runoff from cities or farms, dumping from industry, or drilling for oil, we’re increasingly filling our rivers, seas and oceans with toxic pollutants. Sea life is suffering tremendously. Darko Kapelina is interested in ideas relating to clean sailing.
