But this process for managing ewaste may be used in an unscrupulous way more often than not used, a recent report suggests.“A lot of these materials are being sent to developing nations under the excuse of reuse – to bridge the digital divide,” said Richard Gutierrez, a policy researcher.One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, ewaste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment. Businessmen also pay workers a little money to get back materials such as gold and copper. This lowtech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.” China, for example, has bee a dumping（傾倒，堆放） place for large amounts of ewaste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial（否認(rèn)）, is finally beginning to take the lead. does the passage mainly tell us ?A. Ewaste is a growing problem in developed countries. B.
