My daughter took some notes out of her science book today. She wanted to know if I knew that 3/4 of the earth's surface is made of water. I did know that. She then told me that 97% of that water is salt water. (That's a lot.) Of the 3% left, 2% is made up into glaciers. That leaves one percent for human use!

Did You Know How Much of the Earth's Water We Use?

That is an interesting illustration of just how fragile life is on this planet and how precious water really is. And yet we still want to exploit the planet, destroying the very mechanisms that keep that pure water in supply.
I was completely amazed, as was she! it is hard to imagine the supply being so "limited" and yes, just how much we take that for granted.
I have been thinking about ever since you posted it. It may be one of the keys to unlocking something that is very much on my mind, the preservation of the forests and what's left of the natural world. I'm very glad you posted it!
