Water cycle

Weird but true: there's no such thing as new water

The water cycle is the never-ending journey that water takes as it circulates from clouds to the land to the ocean and back again. This is nature’s way of cleaning and recycling all the water on earth – it’s this fresh water that make life on earth possible.

And because of the way the cycle works – it’s known as a ‘closed system’ – meaning there’s no new water on the planet. The fact is, we are actually drinking the same water that the dinosaurs drank!
