However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 metres (26,000 ft) as the death zone, where it is generally believed that no human body can acclimatize.
High-altitude adaptation in humans is an instance of evolutionary modification in certain human populations, including those of Tibet in Asia, the Andes of the Americas, and Ethiopia in Africa, who have acquired the ability to survive at altitudes above 2,500 meters (8,200 ft). [1]
Elevation, climate, and soil fertility set upper limits on types of crops that can reside in each zone. Populations residing in the Andes Mountain region of South America have taken advantage of varying altitudinal environments to raise a wide variety of different crops. [ 11 ]
The generally strong dependency on elevation is known as altitudinal zonation: the average temperature of a location decreases as the elevation increases. The general effect of elevation depends on atmospheric physics. However, the specific climate and ecology of any particular location depends on specific features of that location.
California [7] Highest incorporated town in California is Mammoth Lakes at an elevation of 7,920 feet (2,410 m) 10,578 feet (3224 m) Alma Colorado: The town limits of Winter Park (9052 feet (2759 m)) extend to 12,060 feet (3676 m). [8] Alma is the highest incorporated city at 10,578 feet (3224 m). [9]
This is a list of places on land below mean sea level.. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included.

The human body has optimal endurance below 150 m (490 ft) elevation. [6] The concentration of oxygen (O 2) in air is 20.9% so the partial pressure of O 2 (PO 2) at sea level is about 21.2 kPa (6.3 inHg; 3.07 psi). In healthy individuals, this saturates hemoglobin, the oxygen-binding red pigment in red blood cells. [7]
