Importance of Water Conservation and Distribution on Earth
Imagine a world without
water.
The planet is a
barren
desert
. There are
no
cool green forests or deep oceans.
The world is
silent
– no rain falls onto the rooftops.
No
clouds
shield our planet from the hot sun. Even the
shape of the land
is different. Without water to wear
them down, the mountains are
jagged and rough
.
There are no Great Lakes, Niagara Falls, and no Grand
Canyon.
