一项新研究表明:氧气正在从越来越广泛的海域中逐渐消失,这可能又是一个由全球变暖所造成的环境问题。如果这个趋势继续下去,海洋生态系统将会遭到破坏。暖水海域不如冷水海域的含氧量高,因此自从科学家们对海洋温度上升所带来的冲击开始表现出担心以来,他们一直在搜集有关海洋 A new study shows that oxygen is gradually disappearing from an ever wider sea area, which may again be an environmental problem caused by global warming. If this trend continues, the marine ecosystem will be destroyed. Since warm waters have a lower oxygen content than cold waters, scientists have been collecting information about the oceans since they began to show concern about the impact of rising ocean temperatures
