How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?

In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.

Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces. They are taller, to reach higher branches. They have shorter tusks （象牙）， and most importantly, longer trunks to dig for water in riverbeds.

Desert clephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families, They drink only every 3-4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders-they seldom root up trees and break fewer branches, and thus maintain what little food sources are available. Yong elephants may even eat the dung （粪便）of the female leader of a group when facing food shortage.

During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine (尿液) to make them muddy!

As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.

Almost every child is scared of something, from monsters in the cupboard to dogs in the park. But the fact that such fears are common and normal doesn’t mean they can be taken lightly. Kids experience fears and phobias (恐惧症) much more strongly than adults. And the influence of the fear can be physical as well as psychological (心理的). It can build up so they almost seem scared of everything-a kind of childhood anxiety. Dr. Creswell says: “Your child may always seem to expect the worst to happen and lack confidence in his or her ability to deal with any challenge.” So don’t make the same old mistake of treating them as if they’re silly for being a “scare cat”. Handing the fears is essential.

Children can be born nervous and., if you have such a baby, you’ll tend to prevent them from getting worried. So if they fear dogs, You’ll keep them away from dogs, but in fact that can just confirm to the child that dogs are scary. What is worse, keeping your child away from what they fear can turn that feeling into a phobia. Instead, you should encourage them to get in touch with the thing they fear, in a safe and supportive environment. Dr. Andy Field, a researcher of childhood fears, says: “You shouldn’t force, for example, a dog anxious child to go up to a dog. But you can approach it yourself, show them there is nothing to be afraid of, stroke (抚摸) it, and talk about the dog being friendly. Once your child dares to stroke a dog-one that’s good with children, of course-then you should encourage them to carry on until they feel calmer, and reward them for “being brave’.”
