Water pollution has existed for all of Earth's history. 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.

Why do you say that your water has been drunk by dinosaurs?

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.
