Voice 1: Glaciers exist on every continent.They are like rivers of flowing ice.They cut their way through mountain valleys.Usually, during warmer seasons, glaciers will melt just a small amount.People living below the mountains use this water.It fills their rivers.It helps their crops grow. They drink it.But, in colder seasons the glaciers will build up again.Snow and rain on the mountains help glacier growth stay constant.But, mountain glaciers are shrinking at too fast a rate.People all over the world are watching it happen.
