For 170 years,members of a tiny American native tribe have lived and celebrated their traditions on a
small piece of land off the Louisiana coast called Isle de Jean Charles.They fished and they farmed,making
livings by hard work amid the bays and marshes(沼泽)．But now the waters that have supported them
are threatening to overwhelm them.
"I don't think we're going to have to have any other choice except to leave because we're getting
washed away by every storm that comes by," said Albert Naquin,chief of the BiloxiChitimacha tribe."We
have lost more and more land,and it keeps happening."
Surrounded by the Gulf of Mexico on one side and the marsh on the other,Isle de Jean Charles sits at
the southern tip of Louisiana's rapidly disappearing wetlands,an area that is 3 to 4 miles long and about a
mile wide.The tribe has been living here since 1840.But about a football field worth of land in the region is
lost every half hour because of erosion(侵蚀),storms and rising sea water-a constant process that is
expected to worsen with climate change.
Isle de Jean Charles has been flooded five times in the last six years,being transformed from a once
lush(繁茂的) landscape into a barren disaster zone.The floodwaters have spread large amounts of salt
across the tiny island,making it nearly impossible for much to grow any more.
The road to their village has been flooded so often,and now only one narrow road is usable,
which is often covered by water.The fire station was closed a few years ago,and the island's church was
relocated.Now,only 25 families are left,with a "few dozen" people.A controversial $900 million system of
sea walls to save endangered communities along the Louisiana coast raised hopes here.But the final
design did not include Isle de Jean Charles because officials concluded it simply would cost too much to
protect the relatively few families that were left..
