[ti:Scientists Collect Seeds in Wild for Climate Change Fight][by:shang05.com][00:00.00]更多听力请访问shang05.com[00:00.12]More than 100 scientists have traveled to faraway places[00:04.84]to collect wild crop seeds in an effort to help battle climate change.[00:11.68]The scientists have been likened to the hero of the "Indiana Jones" movies.[00:19.28]Like him, they have faced dangers from blood-sucking creatures to tigers,[00:25.92]and sometimes used elephants for transportation.[00:31.52]A report on the project was published last week.[00:36.48]It describes the results of a six-year search to collect thousands of wild seeds.[00:44.52]The seeds could be important in feeding a growing human population[00:51.04]at a time when rising temperatures are affecting crop production in some areas.[00:59.24]The Reuters news agency say the scientists traveled by foot,[01:04.68]four-wheeled vehicles, boat, horse and even elephant to reach far away areas.[01:13.60]They collected 4,644 seed samples of 371 wild relatives of 28 world crops.[01:25.56]Many of those wild relatives are said to be endangered.[01:30.24]The Crop Trust, a nonprofit organization that works[01:35.96]to save different kinds of crops, is directing the project.[01:42.20]The group is working in partnership with Britain's Royal Botanic Gardens and Millennium Seed Bank.[01:51.08]Additional financial support comes from Norway.[01:56.24]The project is believed to be the largest organized[02:00.32]international effort yet to collect and protect crops' wild relatives.[02:07.76]Hannes Dempewolf is a scientist and the head of global initiatives at the Crop Trust.[02:15.36]He told Reuters that collecting the seeds was not easy.[02:21.28]He noted that scientists faced extreme "heat, dust, sweat and danger from wild animals."[02:30.52]He added, "The stories these seed collectors brought back[02:36.32]from the field often resemble scenes from an Indiana Jones movie."[02:43.16]Scientists that took part in the seed collection project came from 25 countries.[02:51.40]Some relatives of widely grown crops have developed so plants can survive[02:57.48]severe conditions such as low rainfall, flooding, extreme temperatures and poor soils.[03:06.92]Scientists say the wild crops offer a largely unused source of diversity[03:14.20]for protecting crops against climate change.[03:18.48]Some crops are threatened because of destruction of forests,[03:23.40]climate change, conflict and expanded cities.[03:29.84]Experts say losing this diversity could endanger food security around the world.[03:37.36]A United Nations report says that food supplies are under severe threat.[03:45.28]The report notes that the number of animal and plant species are quickly disappearing[03:52.08]as the world deals with how to feed a rising population.[03:58.16]The U.N. Food and Agriculture Organization[04:02.00]says that people are depending on fewer species for food.[04:08.72]That leaves food production at-risk to organisms, disease,[04:14.36]lack of rain and other weather extremes linked to climate change.[04:20.44]I'm Jonathan Evans. 更多听力请访问shang05.com
