But remember … water can be fresh but never
new. All the water in the world, in the ice caps, the oceans,
the clouds, in the rivers and under the ground, is about a billion
years old. There’s always been the same stock of water on Earth,
it just moves around the planet, changing to ice or seawater or rain.
People can move it around too, but – we can’t
get any more of it! We’ll just have to use our water stock
carefully. And the tiny percentage of the Earth’s water that
humans can drink – fresh water – is ancient too. It could just
be that a dinosaur, thousands of miles away, once drank your next
gulp of water! |
