How to save the wild animalsAnimals are people's friends．But many
wild animals are facing the danger of dying out(灭绝),because the
environment that they are living in has changed greatly．For example,
their living area has become of the development of cities and pollution．
They have no room to live in except the zoo．And many of the wild
animals now can't find enough food to eat．At the same time,   man is
killing off(杀尽)animals just for getting their fur,skin,teeth and meat．
         People should realize how serious the situation is and something
should be done to protect the animals．We are supposed to set up some
nature reserves(自然保护区),so that animals can live freely．Besides,
people should not be allowed to kill the endangered animals or eat their
meat．We should do something to make our world cleaner．Fresh air,
clean water,green grass are all important for animals．The death of the
endangered animals will bring a disaster to human beings．
