Question

Oceans are the biggest source of water, yet they are not fit for human consumption. Why?

Answer 1

• Oceans are the biggest source of water, they contain $97\%$ of water on the earth.
• But they are not fit for human consumption because they contain a high concentration of different salts which makes their water salty.
• Therefore ocean water is not fit for human consumption.

Hence, ocean water is not fit for human consumption.
