沙漠化的形成与地球温室效应、厄尔尼诺现象、森林锐减、植被破坏、物种灭绝、气候异常等因素有着不可分割的关系。特别是过度开发自然资源、过量砍伐森林、过度开垦土地等成为了沙漠化的主要原因。本活动希望同学们通过亲身体验身边的粉尘问题,调查本地区受沙漠化影响造成的降尘问题,了解沙漠化问题,讨论防止沙漠化的个人行为。活动时间:1小时或1周。活动地点:家庭。活动类别:调查、测试。活动准备:透明胶带,放大镜,胶头滴管,培
The formation of desertification has an inseparable relationship with the global warming, the El Niño phenomenon, the sharp decline of forests, the destruction of vegetation, the extinction of species, the abnormal climate and other factors. In particular, over-exploitation of natural resources, excessive deforestation and over-reclamation of land have become the major causes of desertification. This activity hopes that the students will investigate the problem of dust reduction caused by the desertification in the region, understand the problem of desertification and discuss the personal behavior of preventing desertification by experiencing the dust problem nearby. Activity time: 1 hour or 1 week. Venue: family. Activity Category: Investigation, Testing. Preparation activities: Scotch tape, magnifying glass, plastic head dropper, training
