Why are freshwater habitats important?

Some animals live in freshwater habitats for example, fish, hippos, and crocodiles.  Animals need to drink so if we get greedy there might not be any water left.  

1% of the worlds water is available for humans.  70% of the worlds water is ice and 29% of the worlds water is not available because it is too far down in the ground.

If we litter by the river the river will take the rubbish into the sea and pollute the sea.  Don't waste water - people need water!
