The River Thames was once described as “biologically(生物学地) dead”. A waterway polluted with so much industrial waste that no wildlife could survive in it.

But today it has become a thriving (繁荣的) natural habitat and a team of conservationists restoring the famous river have been offered a top environment award for their work.

Ncarly 40 miles of the river have been improved in the last five years through almost 400 Environment Agency restoration projects. As a result, the river is now home to some 125 species of fish, while many others are returning. The river mouth supports shellfisheries and is a nursery ground(育苗场) for bass (鲈鱼) stocks, and the water quality of the Thames has improved.

Alastair Driver, the Environment Agency’s national conservation manager, said that in the last 150 years, the Thames had been polluted seriously and that it had taken thousands of people decades to restore it to its current condition. “Strict regulations for polluting industries and our work with farmers, businesses and water companies to reduce pollution and improve water quality have helped to make the Thames a living river once again.” But he warned that the river’s recovery was still “fragile”, since it was under the pressure from a growing population and climate change. He said advanced projects and cooperation with various people and organizations aim at dealing with the problems the Thames faces and ensuring(确保) it still a famous river for many centuries to come.

Actor, David Suchet, a skillful boater and chairman of the River Thames Alliance, said, “I am fortunate in my life to have traveled widely and enjoyed many other rivers worldwide. But the River Thames is priceless and it is one of the most glittering jewels in the crown of our English heritage.”

Boris Johnson, Mayor of London, said, “The Thames is one of our most precious resources, so I am excited to see that efforts to improve and preserve its good health are being praised on the world stage.”

The ￡ 220,000 prize, awarded at the International Rive Symposium in Australia, will go to the Thames Rivers Restoration Trust.
