'''Animals as a resource '''For humans, animals are a productive resource. First of all, they supply a wide variety of foods that man needs to survive: milk, cheese, eggs, butter, salami and cold meat, etc. Some animal species, such as corals and oysters, are used by man to produce jewels and handicrafts. The hide of some animals is used instead to produce clothes. In many places across the world, animals are still one of the main means of transport. For instance, camels are particularly used in such desert areas as the Sahara desert, while in Northern areas sleighs are drawn by huskies, dogs that are very resistant to cold and fatigue. Every day, animals join man and help him in the most diverse activities. For their innate sensory superiority and their great adaptability to the external climatic conditions, they can carry out tasks that man cannot.
