Seas and Oceans

Water may flow in a thousand channels, but it all returns to the sea.
an African proverb

When viewed from space, the dominant colour of the Earth is blue. Often called the Blue Planet, more than 70 percent of its surface is covered by oceans and seas. With 97 percent of the world’s water, it is clear why seas and oceans play such a key role in maintaining the Earth’s natural balance.
