Write a summary of the following passage:
The coconut tree is very useful. People in the tropics depend on it. They make roofs for their houses from leaves.) Fishermen take fibres from the tops of the coconut trees and make them into rope. They make fishing nets and sails for their boats too. But the nut is the most precious part of the tree. Farmers open the nuts and dry them. There is oil in coconuts and they export this to other countries. It goes into soap, toothpaste, ice-cream, paint and machine oil. The shell of the coconut is useful too. People make it into charcoal. There is milk in coconut too. It is good to drink and very pure. Doctors sometimes use this milk for drip feeds during the war, when they could not get pure water and sugar. Doctors use this milk for those patients who could neither eat nor drink.
