Almost all of Earth's surface water exists in the oceans

Explanation:

Around two thirds of Earth's surface is covered with water. Despite having so much water on the planet, most of it is not usable, as it is saline water. In fact. almost all of the surface water on Earth is saline, more specifically around 97% of it, leaving only 3% of the water as freshwater, though the majority of those 3% also can not be used.

This is actually shows us how important the freshwater is on Earth and that we have to be extremely careful when managing it. The ocean water will be there, and it will be found in abundance, but this water can not be consumed by the people, it can not be used in the industry or in the homes, it can not be consumed by the terrestrial animals, nor it can be used for irrigation.
