美国城市,如波特兰和芝加哥,正在振兴城市河流,以增加娱乐机会和提高生活质量。 American cities like Portland and Chicago are revitalizing their urban rivers to enhance recreational opportunities and improve quality of life. 自2012年以来,波特兰的威拉梅特河已变得可以游泳,而芝加哥的目标是在下一个十年取得类似进展。 Portland's Willamette River has become swimmable since 2012, while Chicago aims for similar progress in the next decade. 尽管1972年颁布了《清洁水法》,但许多河流仍然受到污染,无法开展活动。 Despite the 1972 Clean Water Act, many rivers remain too polluted for activities. 倡导者们强调,要取得成功,就必须改变公众对城市水道的看法的文化观念。 To succeed, advocates stress the need for a cultural shift in public perception regarding urban waterways.
