Envy is seen in calls for a new kattegat bridge to cut the three-hour train journey between copenhagen and aarhus , denmark 's second city , to 30 minutes .

这座倡议中的桥可以使哥本哈根和奥尔胡斯（丹麦第二大城市）之间的列车行程从3个小时缩短至30分钟。

And increasingly they affect not only estuaries and inlets , but also continental seas such as the baltic , the kattegat , the black and east china seas and the gulf of mexico .

而且，他们影响到的不仅仅是河口和入海口就连诸如卡特加特海峡的波罗的海、中国的黑海与东海及墨西哥湾这类的内海也受到了侵害。
