地球是人类的共同家园，但人类的活动却对地球造成了严重的破坏。生物赖以生存的森林、湖泊、湿地等正以惊人的速度消失;煤炭、石油、天然气等不可再生能源因过度开采而面临枯竭;能源燃烧排放的大量温室气体导致全球气候变暖，由此引发的极地冰盖融化、海平面上升等问题威胁到人类的生存发展。
保护地球资源环境、寻求可持续发展模式已刻不容缓。在今年“世界地球日”来临之际，“地球日网络”发起“绿色一代”计划，倡导人类社会经济发展向可持续模式转变。该计划呼吁公众维护三条核心原则：消除人类对化石能源的依赖性，致力于可再生能源的开发利用，创造一个“无炭”的未来;承诺个人消费习惯与可持续发展要求相符合;建立“绿色经济”，通过为贫困人群创造“绿色岗位”使其脱贫，并将全球教育体系转变为环保型。
从20世纪90年代起，中国在每年的4月22日都举办“世界地球日”宣传活动，并根据当年的情况确定活动主题。
