Nature takes care of our different needs very well. It endows every animal in such a way that they are capable of taking care of themselves. This is evident from the fact that in different climatic regions different types of animals are born. Fishes can survive in aquatic environment and polar bears can live comfortably in the snow caped Polar Regions. The camels have also been endowed in such a way that they can survive in the adverse and tough desert climate. For days they have to go without water and food. That is why they have humps on their back.
