简介：“造纸”是中国的四大发明之一，我们都为之自豪。可是，不少同学在平时用纸非常浪费，乱撕乱扔，还不以为然地说：“中国地大物博，造纸资源取之不尽。”真是这样吗？请同学们读读下面的文章，看看你会有什么样的感受呢？

简介：与强烈都市化和持续人口生长，与有限陆地来源一起固定食物生产逐渐地成为了一个紧迫的问题。基于国际谷物的分析(即，大麦，荞麦，玉米，燕麦，米饭，黑麦，蜀黍，大豆，和小麦)在在在2007～2011的时期上的出口和进口国家之间的谷物的收益的贸易和差别，我们探索通过国际谷物贸易节省的土地的大潜力。由陆路节省，我们指当谷物与谷物的相对小的产量与谷物的相对大的产量从一个国家被出口到一个国家时，要求生产谷物的必要数量的陆地的减少的全球总数。我们的情形分析建议贸易将帮助为许多岛国减轻国内可耕地的缺乏的那国际谷物(例如，日本)并且在干旱中东和诺思非洲的国家(例如，叙利亚和摩洛哥)。而且，国际谷物贸易粗略地有潜力产生每年土地的50,092,284ha节省的土地，它是西班牙的尺寸。利用一个类似的概念的定义虚拟水(Hoekstra并且挂了2002)，我们把虚拟土地定义为为商品的生产使用的陆地资源的区域。通过介绍虚拟土地的概念，当静止资源能与人为的社会经济的活动流动，我们相信传统地被考虑的陆地资源。最大的虚拟陆地的流动(>3,000,000ha/year)在美国(美国)之间存在到中国，到中国的巴西，到日本的美国，到墨西哥的美国，和阿根廷到中国。然而，不是所有虚拟陆地的流动必然导致土地节省。因此，更多的努力被需要为在全球规模节省的一块更大的陆地计划虚拟陆地的流动。
