Researchers have found that when the Iroko tree is grown in dry, acidic oil (酸性土壤) and treated with a combination of natural fungi(霉菌) and other bacteria, not only does the tree grow well, it also produces the mineral limestone(矿物质石灰岩) in the soil around its root. The Iroko tree makes a mineral by combining Ca from the earth with CO2, from the atmosphere. The bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon into the soil, keeping it out of the atmosphere. In addition to storing carbon (碳) in the trees' leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture. The discovery could lead to reforestation(重新造林) projects in tropical countries, and help reduce carbon dioxide in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India. The findings were made in a three-year project involving researchers from the Universities of Edinburgh,Granada, Lausanne and Delf University of Technology. The project examined several microbiological methods of locking CO2, as limestone, and the lroko-bacteria way showed best results. Work was funded by the European Commission under the Future&Emerging Technologies(FET)scheme. Dr Bryne Ngwenya of the University of Edinburgh's School of GeoSciences, who led the research, said,"By taking advantage of(利用) this natural limestone-producing process, we have a low-tech, safe, readily employed and easily operating way to lock carbon out of the atmosphere, while improving farming conditions in tropical countries.(热带国家) 1.The passage is mainly introducing_____. 主旨题 A. some useful natural fungi and bacteria B a new way to deal with greenhouse gas C a newly-found tree in West Africa D.
