In the early years of our mankind, they used trees, caves as their shelters. They are live in the forest, animals are dangerous and any time they can attack the human. So that they used trees and caves to sleep. Later they become hunters and have the ability to attack the animals. They made hut with leaves and trees, this hut changed to mud house, and the present house. The ideas change the life style. But there are some people who live in the mud house. Shelters are not only for humans but also for all animals and birds. Sometimes the micro organisms take a shelter in the living body, that results some diseases. Shelter is necessary to humans.
