“I agree that animal has its rights as human rights, are as. This is the kind of expansion.” which said by the United States President Lincoln. This saying shows the importance of the animals. In fact, many animals around us are in danger. Owing to the destroyed homeland, the pollution and the hunting by human. Many of them have dead out and many of them are facing this problem.
Earth is not only the home to human survival, but also the home to the animals. We always say this but never truly care the animals. Due to manage of the environment in China, there was more than 10 kinds of mammals have become extinct, there were more than 20 kinds of rare animals facing extinction. Yangtze River Dolphin is a typical example. Wang CanFa, the China Environmental Science Society executive director, represented that China at the cost of the environment in exchange for "world factory". This cost includes the pollution of one of the mother river of China---Yangtze river. For the high-speed of development. Thus, China overuses the resource of Yangtze river. Thanks to over-exploitation of the Yangtze River, ecosystem of the river changes which is hard for the dolphin to adapt. Another factor is the hurt by ship. Owing to the modern mode of transport, the average annual ship count can not count, equipped with propeller of the vessel is also thousands. So many Yangtze River Dolphins dead under the propeller of ships. Another reason is that Yangtze River Dolphins are individual, small, light gray pale, not obvious, Yangtze River water which perspective is less than one meter is extremely difficult to find out. Although there are relatively few data available on Yangtze River Dolphins’ mortality, at least half of all known Yangtze River Dolphins’ deaths in the 1970s and 1980s were caused by rolling hooks and other fishing gear, and electrofishing accounted for 40% of Yangtze River Dolphins’ deaths recorded during the 1990s. Dolphin's habitat has been severely damaged which lead to the extinction of this specious[1]. Nobody can live without food and water, neither can animals. At present, China’s manufacturing industry accounts for one-fifth of global manufacturing. China has a huge number of domestic factories. This means we also have a lot of rubbished, chemicals, useless liquid, radioactive material and so on which need us to deal with. For example, in recent years, more and more chemical plants and pharmaceutical factories are built near the Yangtze River. They drain sewage which is not processed in the river, so many chemical ingredient and radioactive waste influence the water, plants and fish, including the Yangtze River Dolphins’ food. Due to eating the polluted food, many of them was damaged by this pollution. In 1980s, there were only about 4 hundred wild Yangtze River Dolphins. But only 20 years, they die out. The rate of the number full quickly. Noisy pollution is another pollution which influence the habits of Yangtze River Dolphins. As we know that dolphins use sonar system to identify and locate. But recent years, so many noise pollution caused by human activities deeply hurt the Yangtze River Dolphins. They can’t adapt the noisy environment which lead to a large number of deaths. Progressively more laws are published to limit emission so that we can protect the precious animals that are facing the same situation like Yangtze River Dolphins. Animals have a lot of things which attract humans. Their skin can be made into clothes, bags and any other decorations. They can also be made into health products. That’s the reason why human hunt animals. Owing to the value of animals, people overhunt them. People over hunting them. Thus, many of them dead out and many of them are facing this problem. For instance, overhunting is one of the most important reasons why Yangtze River Dolphins extinct. In the Great Leap Forward, China had set up many dummy factories which produce the leather bags. The raw material is the skin of Yangtze River Dolphins. Despite the intensification of protection measures after the 1980s, poaching and hunting are still taking place, and many Yangtze River Dolphins have lost their lives under fishing equipment. "The baiji appears to be in such bad shape that it would probably take nothing short of a miracle to save it," said Thomas Jefferson, an expert on river Dolphins ,at Hong Kong's Ocean Park Conservation Foundation. Because of the destroying homeland, hunting and polluting. Many animals are in danger, many of them like Yangtze River Dolphins have already dead out. They are also alive, why people do so. Stop killing wildlife life, if you go on like this, the world's wildlife will have been killed, The sky will no longer have a bird that cheerful song, only the human lonely alive. Please do not harm those who careless wildlife life! Let the harmony of mankind and nature.
