Did you know that the water you drank today, may have been drunk by a dinosaur 50 million years ago? Well it’s true.
All the water in the world is constantly being recycled. It is cleaned in a never-ending cycle of evaporation, condensation, and precipitation. But there’s a limit to the amount of pollution the water cycle can handle. Sometimes water gets polluted even before it hits the ground —rain falling through polluted air can form acid rain that may kill plants and animals.
