I would like to get some statistics regarding world GDP on land, and world GDP on bodies of water (oceans, rivers, lakes, swamps, etc).If you have ideas, opinions or sources, please leave them in the comments.
By this, I mean anything earned, created, on water versus anything earned, created, on land. Water is 71% of the earth's surface, land, 29%. My expectation is that 1-2% of GDP comes from water, the rest from land. So, I would include not only fishing, shipping, in the oceans, but, also on rivers, lakes, etc. Certainly, oil taken from under the seas. What about tourism to beach cities created by land based hotels? Well, I suppose those benefits should be split among land and water.
Can you please steer me in the direction of any research that has been done on that question?
