Desalination is the removal of salt from water. Desalination occurs when saltwater evaporates and forms clouds and rain. This is a natural process that is important for all land plants and animals, and there's no reason to try and prevent it.

Direct harvesting is the act of manually collecting or cutting resources, such as crops, fish, or timber, from their natural environment without the use of mechanical tools or machinery. This method involves direct human intervention in the harvesting process, often using handheld tools like knives, sickles, or fishing nets.
Desertification can result from poorly managed human intervention in the savannah. Desertification is the process by which areas of desert are created by the destruction of natural vegetation. This causes removal of vegetation cover, overgrazing, uncontrolled fuel wood collection, hard farming practice and loss of fertile soil and excessive tree felling. Many animals were hunted to near extinction such as the bison and buffaloes. Fortunately, the hunting of these animals had been banned.
