I don't really follow a lot of comments questioning the choice of shape, methodology, exclusion of water in the mantle etc. I believe the purpose of the image is to evoke sense of preciousness and responsibility towards the water we have - maybe how much for granted we take our "blue planet". To me, this is an amazingly effective and visually poignant way of doing just that.
