Argh. Why do ignorant people with no idea what they're talking about answer these questions? (Answer: free points.) Stop guessing, people!
The sea is blue because water absorbs more strongly in the red part of the spectrum than in the blue part. This is a weak phenomenon, so we can't detect it in a bowl of water, but with a large enough body, we can.
As to these "reflecting the sky" people, they've obviously never been diving - if they have, they'd know that everything is blue-tinted due to absorption of other parts of the spectrum.
Other colors in sea water are usually the result of particulates, produced by living mater. The Red Sea contains a kind of algae giving it that color, and most northern seas are greenish or dark because of seaweeds.

the green is most props algea growing in the sea. or it is plankton which is reacting to the light which makes them a green colour. all is very natrual and helps wildlife under the sea a lot.

a pollutant is a substance that is harmful for lilfe.
'no pollution' does not mean that there is nothing else in that water then h2o. there are minerals, and chemical elements, microscopical life-forms(like algae) wich are the natural components of the natural water, and may vary in time, giving that effect.

The color of the ocean reflex the color of the sky... if there's a lot of pollution it will look greenish.. .if not it will look blue.

THE WATER IS NOT COLORED. WHAT YOU SEE IS THE REFLECT OF THE SKY.
