While three quarters of the earth's surface is water, less than one percent is drinkable. The percentage of potable water (.37%) plus (.28%) in groundwater and acquifers makes up the drinkable waters. In a general sense, that makes 99% of the earth's water undrinkable. Perhaps as desalinization plants improve, the seas will prove to be a resource in the future.

The individual supply curve is the supply curve of a single firm producing output. Now say there are X individual producers there at any price P* the total available output is the output of all X producers ( a horizontal summation) this total of each individual supply curve gives the market supply curve. Put it simply all firms sell their output in the market.

Land is completely fixed in total supply. No matter how high the rent, no more can be brought into use. Thus rent serves no incentive function; the same amount of land will be available no matter how high the rent. But the resulting argument that rent is a surplus that could be eliminated without reducing the supply is to look at it from the viewpoint of society only.
