题文

阅读理解 Britain's ed bank, the only one in the world aiming to collect all of the planet's wild plant species, has reached its goal of banking 10 percent by 2010. The Millennium Seed Bank Project, run by Kew Gardens-one of the oldest botanical gardens-will officially deposit the 24,200th species on Thursday, a pink, wild banana from China. More than 50 countries are now on board with Kew's giant task but vast places of the globe, including India and Brazil, still need to join in and donate eds, director Paul Smith said. The ed bank is one of the largest and most diver in the world with more than 1.5 billion eds. Its goal is to help protect the planet's biodiversity during a time of climate change. The wild banana ed is under threat of extinction(灭绝)in Southwest China from agricultural development.It is a vital food source for Asian elephants and important for growing bananas for humanconsumption. Stored at minus 20 degrees centigrade, the eds can last for thousands of years and await the daythat scientists hope never comes-when the species no longer exist in the wild. It is a race against time, Smith said, becau in the last decade alone, 20 plants held in the bank havealready been wiped out in the wild. He estimates that between a third and a quarter will become extinctthis century. "It is urgent and it is happening now. An area, the size of England, is cleared of primary vegetation(植被)every year," Smith said. Becau most of the world's food and medicines come from nature, protecting wild plant species isquite important, scientists say. There are already many other ed banks safeguarding food crops, which only account for 0.6 percent of plant diversity. For Kew's next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 millionpounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.1.
