随着全球经济的发展和伴随而来的环境恶化日益严峻，旨在促进全球环境
保护意识的世界环境日也越来越受到人们的重视。那么就让我们来了解每年6月
5日的世界地球日，它的由来及意义。
　　世界环境日的由来
　　1972年6月5日—16日，联合国在瑞典首都斯德哥尔摩召开了人类环境会议。
这是人类历史上第一次在全世界范围内研究保护人类环境的会议。出席会议的
有113个国家，共1300多名代表。会议讨论了当代世界的环境问题，制定了对策
和措施。
　　这次会议提出了响彻世界的环境保护口号：只有一个地球！会议最后形成并公布了著名的《联合国人类环境会议宣言》（简称《人类环境宣言》），以及包含109条建议的保护全球环境的“行动计划”，呼吁各国政府和人民为维护和改善人类环境，造福全体人民，造福子孙后代而共同努力。会议建议将大会开幕日这天作为“世界环境日”。1972年10月，第27届联大确立每年6月5日为“世界环境日”。
　　世界环境日的意义
　　设立世界环境日，就是要提醒全世界注意全球环境状况和人类活动对环境的危害，强调保护和改善人类环境的重要性。它反映了世界各国人民对环境问题的认识和态度，表达了人类对美好环境的向往和追求。世界环境日也是联合国提高全球环境意识、敦促各国政府对环境问题采取行动的主要媒介之一。
