Climate change, pollution, overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze, India’s Ganges and Africa’s Nile, WWF said on Tuesday.At the global launch of its report “World’s Top 10 Rivers at Risk”, the group said many rivers could dry out, affecting hundreds of millions of people and killing unique aquatic life.
“If these rivers die, millions will lose their livelihoods, biodiversity will be destroyed on a massive scale, there will be less fresh water and agriculture, resulting in less food security,” said Rayi Singh, secretary-general of WWF-India.The report launched ahead of “World Water Day” today, also cited the Rio Grande in the United States, the Mekong and Indus in Asia, Europe’s Danube, La Plata in South America and Australia’s Murray-Darling as in need of greater protection.
Rivers are the world’s main source of fresh water and WWF says about half of the available supply is already being used up.Dams have destroyed habitats and cut rivers off from their flood plains while climate change could affect the seasonal water flows that feed them, the report said.Fish populations, the top source of protein and overall life support for hundreds of thousands of communities worldwide, are also being threatened, it found… The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization, damming and huge influxes of sediment from land conversion.
Climate change, including higher temperatures, also means serious consequences for fishery productivity, water supply and political security in Africa’s arid Nile basin.Tributaries flowing into the Ganges are drying up because of irrigation, WWF said.
What does the text mainly talk about?
A.Saving fresh water in our life. B.How to protect our rivers.
C.An important discovery. D.World’s top 10 rivers are at risk.
We can infer from the text that _____.
A.rivers’ dying out could affect food security
B.there are four Asian rivers mentioned in the passage
C.the Yangtze is polluted thanks to the lack of enough tributaries
D.higher temperatures couldn’t affect fishery productivity
The top 10 rivers are fast dying as a result of the following EXCEPT _____.
A.climate change B.wasting water
C.pollution D.dams
WWF is probably a name of _____.
A.a(chǎn)n organization B.a(chǎn) newspaper C.a(chǎn) magazine D.a(chǎn) report
