Human activity is currently altering global elemental cycles to an unprecedented degree. For example, the invention of the Haber Bosch process, and with it, the ability to make fertilizer from atmospheric nitrogen, has greatly increased dissolved nitrogen (nitrate, nitrite, and ammonium) inputs to coastal waters. Because nitrogen is often a limiting nutrient in aquatic systems, the resulting increase in primary production and subsequent organic matter deposition can lead to O

人类活动正在以前所未有的程度改变全球元素周期。例如，哈伯-博施法的发明，以及利用大气氮制造肥料的能力，大大增加了溶解氮（硝酸盐、亚硝酸盐和铵）进入沿海沃茨的数量。由于氮通常是水生系统中的限制性营养素，因此初级生产力的增加和随后的有机物沉积可导致O
