【答案】As the third longest river in the world，the environmental problems of the Yangtze River have raised concern both nationally and internationally．Not only is the amount of water taken from the river rising，but the waste being put back into the river has also been increasing．As a result，a lot of fish and wildlife are endangered．In addition，the drinking water，which hundreds of millions of people rely on the river for，is unsafe now．Therefore，the balance of the ecology has been badly broken．
The main reason for the present situation of the Yangtze River is mainly because of the rapid growth of the population，which contributes to the rapid development of agriculture and industry．
In order to focus on water conservation and survival of the wildlife，effective laws are needed and more measures should be taken forcefully to prohibit factories and cities along the river from sending out waste and sewage into the river，and only when every one of us takes action，will we be able to win the battle against the pollution．
