只有一个地球 'Only one Earth'

World Environment Day

Europe's oldest national park is a fitting place to contemplate nature's beauty on World Environment Day. Established in 1909, Sarek National Park encompasses 760 square miles of pristine wilderness in northern Sweden. Rapadalen (Rapa Valley), a 22-mile-long valley surrounded by steep mountains, is considered one of Europe's most enchanting landscapes. As beautiful as the remote, high-alpine region is, it is only recommended for experienced and well-equipped hikers. The weather is severe and unpredictable, and there are no accommodations available for tourists.

This year's theme for World Environment Day is 'Only One Earth,' a reprise of the theme from the UN's landmark Conference on the Environment held in Stockholm, which established World Environment Day 50 years ago, in 1972. What's the difference between Earth Day and World Environment Day? Not much! Both days celebrate our fragile planet and serve to motivate people to help preserve it. Earth Day started in 1970 on college campuses in the US, while World Environment Day was created by the United Nations with a goal to 'forge a basic, common outlook on how to address the challenge of preserving and enhancing the environment.' Hey, it's a big planet–there's more than enough room for two days to celebrate it.

世界环境日

欧洲最古老的国家公园是在世界环境日观想大自然之美的合适场所。萨瑞克国家公园建于1909年，占地760平方英里，位于瑞典北部的原始荒野中。拉帕达伦（RapaValley）是一个22英里长的山谷，四周环绕着陡峭的山脉，被认为是欧洲最迷人的景观之一。虽然偏远的高山地区很美丽，但它只推荐给有经验和装备精良的徒步旅行者。天气恶劣且不可预测，游客没有住宿。

今年世界环境日的主题是“只有一个地球”，这是联合国在斯德哥尔摩举行的具有里程碑意义的环境会议主题的翻版。50年前，斯德哥尔摩于1972年设立了世界环境日。地球日和世界环境日有什么区别？不多这两天都庆祝我们脆弱的星球，并激励人们帮助保护它。地球日始于1970年的美国大学校园，而世界环境日是由联合国创建的，目的是“就如何应对保护和改善环境的挑战形成一种基本的、共同的观点”嘿，这是一个大星球，有足够的空间庆祝两天。
