每年，世界各地的人们聚在一起庆祝地球日。这个年度活动的标志是许多不同的活动，从游行到节日，电影节到跑步比赛。地球日活动通常有一个共同的主题：表达对环境问题的支持并教导后代保护地球的必要性。 1970年4月22日庆祝了第一个地球日。一些人认为这是环境运动的诞生，由美国参议员盖洛德·尼尔森创立。尼尔森选择4月份的日期与春天相吻合，同时避免大多数春假和期末考试。他希望吸引大学生和他所计划的环境学习和行动日。威斯康星参议员在目睹1969年加利福尼亚州圣巴巴拉发生的大规模石油泄漏事件造成的破坏后，决定创建一个“地球日”。受到学生反战运动的启发，尼尔森希望他可以利用学校校园的能量，让孩子们注意空气和水污染等问题，并将环境问题纳入国家政治议程。有趣的是，尼尔森从1963年当选总统的那一刻起就试图将环境置于国会议程中。但他反复告诉美国人并不关心环境问题。所以尼尔森直奔美国人民，把注意力集中在大学生身上。来自美国2000所大学，大约10,000所小学和中学以及数百个社区的参与者聚集在当地社区，纪念第一个地球日。该活动被称为教学活动，活动组织者专注于支持环境运动的和平示威活动。在第一个地球日，大约有2000万美国人涌入当地社区的街道，展示了支持全国各地大大小小的环境问题。活动的重点是污染，杀虫剂的危害，漏油事故，荒野的丧失以及野生动物的灭绝。第一个地球日促成了美国环境保护局的成立以及清洁空气，清洁水和濒危物种行为的通过。 “这是一场赌博，”盖洛德后来回忆说，“但它确实奏效了。”现在在192个国家观察到了地球日，并在全世界数十亿人的庆祝活动中庆祝。地球日官方活动由非营利组织地球日网络协调，该组织由1970年第一个地球日组织者Denis Hayes担任主席。
Every year, people from all over the world come together to celebrate Earth Day. The symbol of this annual event is a number of different events, from parades to festivals, film festivals to running competitions. Earth Day activities usually have a common theme: expressing support for environmental issues and teaching the need for future generations to protect the planet. The first Earth Day was celebrated on April 22, 1970. Some people think this is the birth of environmental movement, founded by US Senator Gaylord Nelson. Nielsen chose the April date to coincide with the spring, while avoiding most spring breaks and final exams. He hopes to attract college students and his planned environmental learning and action days. Senator Wisconsin decided to create an “Earth Day” after witnessing the damage caused by the massive oil spill in Santa Barbara, California in 1969. Inspired by the student’s anti-war movement, Nielsen hopes that he can use the energy of the school campus to alert children to issues such as air and water pollution and to integrate environmental issues into the national political agenda. Interestingly, Nielsen tried to put the environment on the Congress agenda from the moment he was elected president in 1963. But he repeatedly told the Americans that they are not concerned about environmental issues. So Nelson went straight to the American people and focused on college students. From 2000 universities in the United States, approximately 10,000 primary and secondary schools and hundreds of community participants gathered in the local community to commemorate the first Earth Day. The event is called a teaching activity and event organizers focus on peaceful demonstrations that support environmental movements. On the first Earth Day, about 20 million Americans flocked to the streets of local communities to demonstrate environmental issues that support large and small across the country. The focus of the campaign was pollution, pesticide hazards, oil spills, loss of wilderness and extinction of wildlife. The first Earth Day led to the establishment of the US Environmental Protection Agency and the passage of clean air, clean water and endangered species. “This is a gamble,” Gaylord later recalled, “but it did work.” Earth Day is now observed in 192 countries and celebrated in celebrations of billions of people around the world. Earth Day official events are coordinated by the non-profit Earth Day Network, chaired by Denis Hayes, the first Earth Day organizer of 1970.
