Did
you know that 71% of the surface of the earth is water, with 97% of that salt water? That leaves a mere 3% in freshwater lakes, ponds, rivers, and streams.
And
that's just water on the surface.
There's
also water in the ground and in the air - although I suspect much of it above the
earth has reached the ground in the form of rain in Bristol the past week.
So
keep your umbrellas handy - and wish for sunny days.
