People in a caravan are glad to see an oasis, because they usually traveled in deserts. There are limited amount of water located in a desert, and animals and humans cannot survive without water. Whenever they see a oasis, they are happy, because not only does it supply them with water, but it may also draw game (animals that could be eaten) to that area, which provides both water and food
