It is estimated that Tuvalu will disappear within 50 years, that is, 10000 days. This country is the second smallest island country in the world, and it is also a country that is about to disappear. The whole island country of Tuvalu is very low, with the highest elevation of only 4.5 meters, which is one reason why Tuvalu is about to disappear. Of course, this is not the main reason. In fact, the main reason is that the sea level here is rising and the temperature here is also rising. This series of changes will lead Tuvalu to sink into the ocean within 50 years.
