The earth is a beautiful transparent blue water polo.

On the earth, water accounts for 70% of the earth's area. Although the earth has a large amount of water resources, only 3% of the real drinking freshwater. All living things on earth need water. If we waste it like this again, sooner or later the fresh water on the earth will be exhausted. We should know that there is no life without water. Let's face the reality positively and cherish all the precious water resources.
