Water resources are things like rivers, lakes, and underground water sources that provide us with fresh water to drink, to use for things like growing food and for cleaning. We need water for our health, so it's really important to protect our water resources and make sure that everyone has enough clean, fresh water. To do this, we have things like rules and laws that protect our water and make sure we don't pollute it with things like dirty waste or chemicals. That way, we can keep our water clean and make sure that everyone can use it.
