What if Seawater becomes Freshwater? + more videos | #aumsum #kids #science #education #children

First of all, the biggest advantage will be that it will solve the water crisis all over the world.
However, there will be quite a number of disadvantages.
Firstly, most of the fishes will die.
Why?
In freshwater, due to a process called osmosis the cells of the fishes will swell up, thus eventually killing them.
Secondly, experts believe that tiny organisms called zooplankton and phytoplankton which are critical to the marine life food chain, will die off, leading to mass extinction of marine life.
In addition to this, phytoplankton produce half of the world's oxygen via photosynthesis.
Without them, there will be far less oxygen available for us to breathe.
Lastly, experts believe that salt in the seawater has a major impact on ocean currents which in turn influence our climate.
However, as more research is required experts don't exactly know what will happen if all the seawater becomes freshwater.
