目前,地球上已有多种资源濒临枯竭。有些专家学者担心,世界资源终将消耗殆尽,资源的末日终会到来。然而人类拥有的大海大洋是个取之不尽用之不竭的资源宝库。随着现代科学的发展,人类将向海洋进军,海洋资源的开发利用有着广阔的前景。 1、大量的海水资源。陆上许多地方水源奇缺,而海洋则拥有极为丰富的水资源。世界海洋的海水达137万立方千米,海洋上漂流着大量淡水冰块,即从大陆冰川脱落的冰山,其总重量约为7.65×10~(12)吨,93％分布在南半球,其体积相当于黑海总容量的1％。世界海洋表层每年约有448万立方米的水被蒸发,这相当于苏联境内全部河流流量的100倍。海洋 At present, there are already many kinds of resources on the planet that are exhausted. Some experts and scholars worry that the world’s resources will eventually be exhausted and the end of resources will come. However, the sea of ​​oceans owned by mankind is an inexhaustible treasure house of resources. With the development of modern science, human beings will march into the sea and the development and utilization of marine resources will have broad prospects. 1, a lot of sea water resources. There is a scarcity of water in many parts of the land, and the ocean has extremely rich water resources. The seas of the world’s oceans reach 1.37 million cubic kilometers, and there are a large number of freshwater ice blocks floating on the oceans. That is, icebergs detached from continental glaciers have a total weight of approximately 7.65×10 12 tons, and 93% are distributed in the southern hemisphere. It is equivalent to 1% of the total capacity of the Black Sea. About 4.48 million cubic meters of water are evaporated every year on the surface of the world’s oceans, which is equivalent to 100 times the flow of all rivers in the Soviet Union. ocean
