Animals and fish die in the water, herds stir up sediments, towns discharge sewage, heavy metals dissolve out of rocks. etc. The problem is tha larger human settlements and increased industrial and agricultural activites are discharging more and more pollution into localized areas.

The water moves continuously through the water cycle.
None. The water cycle only recycles the water that has been on Earth for the past 13 billion years.
of course, the water never goes anywere it evaporates and eventually it rains that's why it's called the water cycle
Earth-Wide Desertification, seems like.
not sure, but the ancient roman believed a god name beshoy controls recycling... maybe you should check it out on google.

Water cycle was not discovered in 1991, it has always been. It is the process of using and recycling the earth's water.
There are approximately 326 million trillion gallons of water on the Earth. Water is a constant moving cycle and there is a lot of it on the Earth. The mountains under water are just land masses that have been covered by the water.

Nearly all the water on Earth has been here since long before the dinosaurs. It is constantly recycled via the water cycle. During the millions of years that dinosaurs existed, at least a good portion of the water molecules on Earth passed through a dinosaur at some point, only to evaporate and rejoin the water cycle. So, at least some of the water you drink was in a dinosaur at some point.
it has been found through the water cycle
