The trees on the island in the picture are coconut palms. They are very useful because they grow well in sandy and salty places near the seashore where other kinds of trees can't grow. The coconuts give food. The islanders can dry the nuts and sell them to make oil. They can also use the trunks of the trees for building and the leaves for making roofs for their houses. There is no cold weather in the islands so the islanders do not need houses with thick walls. This house is open on all sides. There is a stone floor and a roof made of palm leaves. There are mats on the floor. The islanders make the mats from dried leaves
