9. Melting ice
Earth is getting warmer and the ice is melting at the North and South Poles. As this ice changes to water, the sea level is getting higher. This is dangerous for low countries like Bangladesh, and for low islands.
Tuvalu is a country in the Pacific Ocean and it's made of groups of islands. Parts of the capital, Funafati, are now only 10 centimeters above sea level. Scientists think that the ocean will soon cover the land, and the people who live there will have to move to other countries like New Zealand or Australia.
