If they melt the water level will rise and animals like polar bears and penguins will loose land and it would be very hard for them to survive and they will have to find somewhere new to live. And cities and towns beside there will probably get flooded and the people there will also have to move. We need to help this planet soon. If we don’t it will just keep getting worse. And the climate change is pretty bad at the moment. We don’t know what will happen by 2030 but if we don’t help now it will be very bad.
