Ice Caps
The earth has two ice caps, one in the north, in the Artic and one in the south, in Antarcica. Each ice cap contains many bilions of tonnes water. If the weather is too warm, those ice caps will melt. Scientists think the earth is getting wamer because of all the green house gases. Many people think that these changes to our weather will be the biggest problem problem caused by pollution in the next hundred years.
Why "the Ice Caps" are melting today? What do you think to contribute it?
