Why do you think it's important that only 3% of the water on Earth is freshwater?

the earth has an incredible amount of water, but only the 3% of all of it, fresh water, can be used for human use like drinking water, showers/baths, etc

Explanation:

the rest of the water is used for oceans and cannot really be used for human's everyday use, only freshwater can. There are still fish and other animals that live in freshwater though so it is important for humans not to use too much of it
