Well over 600 million people around the world depend on wetlands for their livelihoods, such as fishing or fanning.(3)Yet experts say since 1900, 64 percent of wetlands have disappeared and the rest are on the decline.
All of our fresh water comes from wetlands. The wetlands indeed also clean and purify the water of pollution. They also help to store carbon. They provide livelihoods. They’re also critical for us in terms of disaster risk reduction—helping people to protect their livelihoods and their homes against the impacts of rising sea level, of tsunamis and hurricanes.
(4)Besides providing resources for fishing, farming, water and fodder, they’re a source of pleasure for millions of people. It is in wetlands that we spend our holidays. They are the source of sustainable development and they are vital for our future and for our children’s future.
Besides losing 64 percent of the world’s wetlands since 1900, about 40 percent of the remaining wetlands have been degraded over the last 40 years. The decline continues at a rate of one and a half percent annually because humans build their civilizations near them.
3. What percentage of wetlands has disappeared since 1900?
4. Why are wetlands important according to the news?
选项
A、They are in declining at a high rate.
B、They offer many resources to humans.
C、They help to store carbon dioxide.
D、They increase natural disaster risks.
答案

解析
