Question

What will happen if the seas and oceans contain only freshwater?

Answer 1

1. Marine organisms would die as they are capable of surviving only in seawater (saltwater).
2. The coral formation could not take place as they are made up of calcareous minerals.
3. Salt is quite important in daily usage.
4. We would have to rely on artificial production without natural salt, which would incur a lot of monetary and infrastructural expenses.
5. Saltwater can hold heat better.
6. Sealife is adapted to saltwater.
7. Ocean currents would be completely disrupted.
