Ice caps are melting because it is getting warmer. This causes water levels to rise and countries are beginning to sink. Lots of animals also live in the ice caps. If there homes melt they could go into extinction.
It is getting hotter and hotter in the atmosphere. Like mentioned in problem 2 ice caps are melting. This problem is caused by pollution. As well as it getting hotter the air is also getting dirtier making it unsafe to inhale.
