Effects on Citizens
Tourism is a HUGE part of the Maldives. In fact, most of their profit comes from the luxury hotels and swim locations. But, once the islands are no longer there, it will become harder for the people to earn money.
Since the Maldives mainly focuses tourism, they have to most of their money on tourism too. Since handling hotels isn't exactly cheap, their nation isn't doing very well.
The Other Side
Tourists only see the good side of the Maldives. On the side where most of the citizens live, the water is trashed with bottles, wrappers and oil from sea planes.
Girls and Women
Since the women are in charge of taking care of the hotels, most of them never learned how to swim. This could become a problem when there becomes a time when their nation has to go under water.
