10 of the Most Endangered Animals
The extinction of at least 500 species of animals has been caused by man, most of them in this century. Today there are about 5,000 endangered animals and at least one species dies out every year. The number is rapidly growing, some species becoming endangered without most of us even knowing it. Their value is of utter importance, since they are responsible for a variety of useful medications. The first step towards saving animals is to learn as much as possible about them. So here is a look at some of the most endangered species of animals around the world:
1.Greater Horseshoe Bat- There are fourteen species of bat in Britain and all of them are endangered.The greater horseshoe bat is one of the rarest. There are currently 35 recognised maternity and all-year roosts and 369 hibernation sites. Current estimates range between 4,000 and 6,600 individuals. They have also suffered from the use of insecticides (poisonous chemicals sprayed on to crops to kill harmful insects) which have deprived the bats of their insect food.
2.Siberian Tiger- It is highly endangered and there may be fewer than 200 in the wild, probably all in special nature reserves. The are hunted because a poacher can feed his family for a year on the proceeds of just one tiger kill.
3.Loggerhead Turtle- This threatened reptile lives in the Mediterranean Sea, as well as the Black Sea and AtlanticOcean. The turtle was once intensively hunted for their meat and eggs, but its fat was also used in the cosmetic industry. Many of these animals die annually caught in the fishing nets of crabfishers. In Turkey, hotels have been built right on its breeding sites.
答案补充 4.White Tailed Fish Eagle- Before man experimented with the use of pheromones, this spectacular bird of prey was much more numerous than it is today. They have also been hunted by shepherds and gamekeepers that considered them a threat to their sheep or birds. With intense conservation actions, the populations in eastern Europe recovered, recovery plans are aimed at colonizing some traditional breeding areas in Europe. 答案补充 5.Mandarin Duck- This bird can be seen Britain, but its native home is across eastern Asia, in Russia, China, Korea andJapa. Worldwide population status is unknown, the current Asian population being somewhere under 20,000. Extinction of these beautiful birds is due to mainly loggers, hunters and poachers. Known predators include mink, raccoon dog, otters, polecats, eagle owls and grass snakes. 答案补充 6.Lion-Tailed Macaque- These animals live in several areas in Karnataka, Kerala and Tamil Nadu. Many of India’stropical forests, the monkey’s natural habitat, have been cleared and replaced with tea and coffee plantations. As with so many mammals, currently the main threat in the wild is destruction of their habitat. Poachers have also captured baby macaques, often killing their parents in the process, for illegal export to collectors. 答案补充 边幅问题,到这里看看吧,只要其中一种估计也能应付你的作业了
