| 摘要： | In 1983, famed ocean explorer and oceanographer Jacques Cousteau sailed his research vessel Calypso down the Mississippi River, sparking a conversation that continues to this day about rivers, their health and what they mean to a healthy ecosystem. Cousteau said his goal was to '"stand back,' so to speak, and examine how the river is used and what are the benefits and costs of this grand interaction." The resulting film was broadcast in 100 countries, as well as at the 1984 World's Fair in New Orleans. The journey and film helped spread the recognition that the levees, locks and dams that contained the Mississippi River, controlling its floods and enabling a river navigation network unmatched in the world, also imposed costs on the environment. Taming and harnessing the Mississippi River meant reducing the wetlands that used to surround it, which in the past were watered by periodic floods. Narrowing and focusing its waters also carried nutrients into the Gulf of Mexico that affected its waters. In 1986, Congress declared the Upper Mississippi River System "a nationally significant ecosystem and a nationally significant commercial navigation system," a declaration that linked the two functions of the river. This linkage was enthusiastically embraced by navigation supporters. |
