三、爱护我们的地球
ladies and gentlemen,we are in the “environment area”.People used to collect waste in dustbins.Then the rubbish was sent to be buried or burned,am I right?Well,now theres a system where the waste is disposed of using the principles of ecology.A giant machine,always greedy for more,swallows all the waste available.The rubbish is turned into several grades of useful material,such as “fertilizer” for the fields and “soil” for deserts.Nothing is wasted,and everything,even plastic bags,is recycled.A great idea,isnt it?
先生们、女士们,我们来到了“环境区”.人们过去使用垃圾箱收集垃圾.然后垃圾会被送走埋掉或烧掉,我说的没错吧?现在,这里是一个使用生态学原理处理垃圾的系统.一个巨大的机器,总是吃不饱,吞食掉所有的垃圾.垃圾被转化为几个等级的有用材料,比如说农田用“肥料”和沙漠用“土壤”.什么都不会浪费,所有垃圾,甚至塑料袋也被回收利用.很伟大的想法,不是吗?
