Sound of clock ticking
Imagine that the water in this cup
represents all of the water on the planet Earth.
Take 20 milliliters of that. This is ice: trapped in glaciers, which while melting rapidly we cannot use.
Take 3 milliliters more. That's water too deep beneath the surface for us to reach and use.
Take another 4 milliliters. This is polluted. So polluted in fact that we CANNOT reclaim this water,
no matter how much treatment it receives.
Take 3 milliliters of what's left.
Everything that remains... is ocean water.
You can make fresh water out of this, but to do so is a long, arduous, expensive process.
We are left with all the fresh water this planet has to offer.
Do we need to take care of our water? Is clean, fresh water unlimited?
