Our planet has a limited supply of land. Approximately thirty per cent of the earth's surface is above water and not all of that readily habitable. The total population of the world, whatever it may be at any given moment, must use the resources of this world's land to survive and satisfy human needs and wants. Not only is our world one of limited resources, the resources we do have are unevenly distributed. No two pieces of land are equal in terms of utilization.
Some plots of land have multiple utility.
Some are near water or receive rainfall. Some are not and do not. Some land contains minerals, oil, metals and various chemicals. Some is apparently barren in terms of our present knowledge and technology. The person receiving a few acres in the middle of the Gobi desert has a high probability of dying of thirst.
