Animals are all around us, so it is easy to think that we know exactly what animals are.
But some animals have fur or feathers; others have shells or males, while many have no hard body parts at all. Animals often have eyes, ears and legs.
Animals are also the only living things that have muscles and nerves. Animals with complicated nervous systems, such mammals and birds, react more quickly than any other living things. Such animals as the tiger, black rhino and giant panda are now so rare that they are endangered. In just 10 or 20 year time, the only place to see them may be in zoos.
Animals are in danger for many reasons, and most of these are to do with humans. People collect animals as pets, and hurt them for food and for ‘fun’. They destroy their habitats, leaving the animals with nowhere to live. We must look after the animal| we have left, before it is too late. Напишите кратко пожалуйста,даю 29 баллов
