What will happen if all glaciers get away?

Glaciers are the main source of water for Rivers. If it melts , then the rivers are gonna dry very soon

This will actually happen if the solution of global warming have not been find.Also we need to control the pollution to escape from such problem.I think the situation will not occur till 100 years.After that if it actually occur we need to change the enviornment by anyway.There is a great flood by this event.Whole world will sink in it.That is very worst situation for mankind.

I just saw a special about this. Mass destruction would happen. Tsunami's. A wave that would hit the eastern seaboard, as far in as the middle of Pennsylvania.
