The natural environment encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather, and natural resources that affect human survival and economic activity. [1] The concept of the natural environment can be distinguished as components:

Oceans
An ocean is a major body of saline water, and a component of the hydrosphere. Approximately 71% of the Earth's surface (an area of some 362 million square kilometers) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 meters (9,800 ft) deep. Average oceanic salinity is around 35 parts per thousand
(ppt) (3.5%), and nearly all seawater has a salinity in the range of 30
to 38 ppt. Though generally recognized as several 'separate' oceans,
these waters comprise one global, interconnected body of salt water
often referred to as the World Ocean or global ocean.[5][6] The deep seabeds
are more than half the Earth's surface, and are among the
least-modified natural environments. The major oceanic divisions are
defined in part by the continents, various archipelagos, and other criteria: these divisions are (in descending order of size) the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean.
