Water covers 71% of the Earth’s surface. In fact, the blue color of oceans and seas is the reason, why our planet looks blue from the space and has a name the Blue Planet. Water is vital for all forms of life. It also plays an important role in the world economy.
Water supplies are used for agriculture, fishing (in both salt and freshwater bodies), and long-distance transportation of commodities and manufactured products. It is also a central substance for many sports, such as swimming, boating, boat racing, surfing, and diving.
Water usually becomes the reason of political conflicts as well. Not all people on Earth have free access to safe water even nowadays. However, in 2006, the United Nations issued a report, which stated that there is enough water for everyone, but access to it is affected by mismanagement and corruption.
The organizations concerned with water protection include WaterAid, the International Water Association, the American Water Resources Association and Water 1st. They all undertake projects, which aim to use effective water management, to reduce poverty.
By the way, 96.5% of the planet’s water supplies lie in seas and oceans. And only 2.5% of it is freshwater, which, in fact, is mostly contained in ice covers. While there are many large bodies of water all over the planet earth, there are only five big oceans.
