河流的狂野舞蹈(The Wild Dance of the River)

你是否对美国一些河流的纯净感到惊讶？这种美丽在很大程度上是由于保护政策。自1968年以来，《野生和风景河流法》保护了209条河流中的20400多公里。虽然这似乎是560多万公里的一小部分，但每个受保护的路段都至关重要。今天图片中出现的137公里长的风是真正的野生动物绿洲。

Are you surprised by the purity of some rivers in the United States? This beauty is largely due to conservation policies. Since 1968, the Wild and Scenic Rivers Act has protected over 20400 kilometers of 209 rivers. Although this may seem like a small part of over 5.6 million kilometers, every protected road section is crucial. The 137 kilometer long wind that appears in today's picture is a true oasis of wildlife.
