摘要
海洋是地球生命的摇篮。正如现代环保运动的代表人物、海洋生物学家蕾切尔·卡森在《海洋传》中所说的那样,'海洋就像流淌不息的河,是万物之始与最后的归处。'海洋连通一体,占地球表面积的70%,是最大的地表生态系统。海洋还是全球环境的调节器,大气中70%的氧是海洋生产的,海洋中的二氧化碳含量比大气中的高60倍,是碳汇的储存库;海洋每年蒸发出450万立方千米的淡水,90%以降雨的形式返回陆地和海洋;海洋还有很强的净化能力,能够分解和消除某些有害物质。
The sea is the cradle of life on Earth.As Rachel Carson,a marine biologist and representative of modem environmental movement,says in her book,The Sea Around Us,that the sea,just like running rivers,is the wigin and destination of all things on earth,connected as whole and accounting for 70%the surface area of the earth,the sea is the largest ecosystem on Earth.The sea serves as a regulator of global environment.It provides 70%of the oxygen in the atmosphoe,its CO2 content is 61 times taofthe atmosphere and it is a huge carbon pool.4.5 million cubic kilometers of fresh water is evaporated from the sea each year and 90%of tbe evaporated amount falls to the land and into the sea in the way of rainfalls.The sea also has a very strong purifying capacity and can decompose and eliminate some hairnfiil matters.
