Unit 2 Working the land reading课时作业

一、阅读理解

文体 说明文 题材 环境保护 　　The things we consume，from iPhones to cars to IKEA furniture，have costs that go well beyond their purchase price.What if the soybeans used to make that tofu you ate last night were grown in fields that were cut out of tropical rainforests？Or what if that T－shirt you bought came from an industrial area carved out of high－value habitat in Malaysia？Unless you buy sustainably sourced food or goods，however，it can be hard to know just how consumer purchases affect groups of animals or plants-until now.

　　Daniel Moran from the Norwegian University of Science and Technology and Keiichiro Kanemoto from Shinshu University in Japan have developed a technique that allows them to realize threats to wildlife caused by the world－wide supply chains.They've used this technique to create a series of world maps that show the species threat hot spots for individual countries.

　　The researchers calculated the percentage of threat to an animal or a plant in one country due to consumption of goods in another.They focus on 6 803 animals and most of them are easily hurt or in danger of dying out.They found that US consumption caused species threat hot spots in Southeast Asia，but also in southern Europe，throughout Central America and into southern Canada.

　　The researchers say finding the relationship between consumption and environmental impacts offers an important opportunity for governments，companies，and individuals to find ways to act against them and do something connected with trade and industry.For example，Indonesia local government can only control the producers whose products cause losses of various plants and animals and cutting or burning down the trees.But if the EU wants to look at its role in causing those problems in Indonesia，they could look at the maps and see what kind of impacts EU consumers are having on that country and then decide to adjust their research programmes or environmental priorities and make changes."
