This movement managed to force the first environmental laws out of the conservative Nixon administration: the National Environmental Act of 1969, the Clean Air Act of 1970, the Clean Water Act of 1972, and the Endangered Species Act of 1973. Then as now, the focus in America was on “green” topics (clean water, fresh air, and biological diversity) rather than with the “brown” topics of ecological disasters such as the Chernobyl (or Harrisburg) disaster, which have played a dominant role in mobilizing Europeans.
这一运动迫使保守派的尼克松政府颁布了第一批环保法律，包括1969年的国家环境法案，1970年的清洁空气法案，1972年的清洁水法案以及1973年的濒危物种法案。像现在一样，当时美国关注的是所谓“绿色”议题(即清洁水源、新鲜空气以及生物多样性)，而不是有关生态灾难的“棕色”议题，例如切尔诺贝力(或者哈里斯伯格)灾难。这些灾害在调动欧洲人上发挥了重大作用。
