中文对照翻译 背景资料：世界地球日
4月22日是世界地球日，我国今年确定的主题是“善待地球，保护环境”。
地球日起源于美国。1969年，民主党参议员盖洛德·尼尔森提议，在美国各校园内举办有关环境问题的讲习会，并将次年的4月22日作为“地球日”。当时25岁的哈佛大学法学院学生丹尼斯·海斯很快将这一提议变成了一个在全美各地展开大规模社区性活动的具体构想，并得到很多青年学生的热烈支持。1970年4月22日，美国首次举行了声势浩大的“地球日”活动，各地约2017万人参加，当时被誉为二战以来美国规模最大的社会活动。
1990年4月22日，全世界140多个国家、2亿多人同时在各地举行了多种多样的宣传活动，主题是如何改善全球整体环境。这次活动使人们更加清醒地认识到，随着全球工业的不断发展，大气臭氧层遭到破坏，由此带来的全球气候异常变化，正在成为直接威胁人类生存的世界性问题。这项活动得到了联合国的首肯，其后，每年的4月22日被确定为“世界地球日”。
目前，世界环境问题越发突出，水土流失、土地沙漠化、淡水资源污染等。据联合国公布的数字表明，20世纪90年代全球森林面积以平均每年2.4%的速度缩减，近2017年来，全球消失的森林总面积达到9400万公顷。目前全球近二分之一的陆地表面和10亿以上人口受到沙漠化影响。在大气污染方面，从1965至1998年，全球二氧化碳排放量翻了一番。目前世界上许多国家正面临水资源危机：12亿人用水短缺，30亿人缺乏用水卫生设施，每年有300万到400万人死于和水有关的疾病。到2025年，水危机将蔓延到48个国家，35亿人为水所困。
世界地球日活动的举办，以期唤起人类爱护地球、保护家园的意识，促进资源开发与环境保护协调发展。我国从20世纪90年代起，每年4月22日都举办世界地球日纪念活动。
