高山上的空气含氧量小于比低海拔地区，所以呼吸时心脏会跳动地更快，身体也会消耗更多能量。

Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy.

低含氧量导致细菌滋长，这些细菌会破坏硝酸盐——海洋微生物及浮游植物的重要营养物质之一。

Low oxygen levels encourage the growth of bacteria that destroy nitrate - a vital nutrient for the ocean's microscopic plants, or phytoplankton.
