The Ocean covers 70% of the Earth’s surface, which is comprised of coastal waters (including estuaries and lagoons), coral reefs, soft bottom continental shelves, upwelling continental shelves, open oceans and polar oceans.
The ocean is the largest eco-system on the planet containing infinite mystery as its wonders lie mostly concealed. What happens below the surface is a critical interplay of nature which needs to be understood if it is to be preserved. According to Nicolos Hulot in his book, One Planet, a recent study is sited, which suggests that 99% of marine species have yet to be discovered and that most of the planets biodiversity is in the sea. Taking care of our coasts is especially important as the majority of the organisms that live in the sea breed here. Over fishing, pollution and rising water temperatures are all of major concern as they are all having extraordinary affects on our ocean life. It is estimated that world fish stocks are no more than one-sixth of what they were in 1990 .
The Earth’s oceans and atmosphere have been said to have a kinship to the human body’s respiratory and circulatory systems. For more information on this and the entire oceanic ecosystem go to Ocean Alive .
