The most important resource for our planet is water resources, and fresh water only accounts for a very small proportion of the planet ’s water resources. Most of the planet ’s water resources are salty and inedible sea water resources.
At this time, some people may ask, if we turn all the sea water into fresh water, is this not a very good thing for us? Because after all of it has been turned into fresh water, can we not drink it directly?
Actually it is not. If all the seawater on the earth is turned into fresh water, this will cause unimaginable and serious damage to the environment of our earth.
For example, after the earth ’s seawater becomes freshwater, the freezing point of the earth ’s oceans will rise, in other words, the earth ’s oceans will freeze more easily. Once the ice of the earth’s oceans will affect the earth’s heat cycle, the frozen sea surface will reflect the sun’s rays and affect the atmospheric circulation, directly affecting the earth’s entire heat system. The earth will usher in a new ice age.
Secondly, if we think that all of the earth ’s seawater will be turned into freshwater, it will seriously damage the earth ’s ecosystem. The largest and most important natural system of the earth is in the ocean. These creatures live on seawater. If we replace all the sea water with fresh water, the organisms living in the ocean will lose their living environment and become extinct. The earth will usher in another species extinction.
Therefore, even if fresh water is precious to us humans, sea water is even more important to the earth’s ecosystem.
