Hw d yu feel when yu see these?
1972年6月5日联合国在瑞典首都斯德哥尔摩召开了联合国人类环境会议，会议通过了 《人类环境宣言》，并提出将每年的6月5曰定为“世界环境日”。同年10月，第27届联合国大会通过决议接受了该建议。世界环境日（Wrld Envirnment Day)是联合国促进全球环境意识、 提高政府对环境问题的注意并采取行动的主要媒 介之一。
D yu knw abut Wrd Envirnment Day?
联合国系统和各国政府每年都在6月5日 这一天开展各项活动来宣传与强调保护和改 善人类环境的重要性。联合国环境规划署每年6月5日选择一个成员国举行“世界环境日”纪念活动，发表《环境现状的年度报告》及表彰“全球500佳”，并根据当年的世界主要环境问题及环境特点，有针对性地制定每年的“世界环境日”主题。
世界环境日的意义在于提醒全世界注意地球状况和人类活动对环境的危害。要求联合国系统和各国政府在这一天开展各种活动来强调保护和改善人类环境的重要性。
