When you were trying to figure out what to buy for the environmentalist on your holiday list，fur probably didn't cross your mind．But some ecologists and fashion（时装）enthusiasts are trying to bring back the market for fur made from nutria（海狸鼠）．

Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles．"It sounds crazy to talk about guilt﹣free fur ﹣unless you understand that the nutria are destroying vast wetlands every year，" says Cree McCree，project director of Righteous Fur．

Scientists in Louisiana were so concerned that they decided to pay hunters ＄5 a tail．Some of the fur ends up in the fashion shows like the one in Brooklyn last month．

Nutria were brought there from Argentina by fur farmers and let go into the wild．"The ecosystem down there can't handle this non﹣native species（物种）．It's destroying the environment．It's them or us，" says Michael Massimi，an expert in this field．

The fur trade kept nutria in check for decades，but when the market for nutria collapsedin the late 1980s，the cat﹣sized animals multiplied like crazy．

Biologist Edmond Mouton runs the nutria control program for Louisiana．He says it's not easy to convince people that nutria fur is green，but he has no doubt about it．Hunters bring in more than 300，000 nutria tails a year，so part of Mouton's job these days is trying to promote fur．

Then there's Righteous Fur and its unusual fashions．Model Paige Morgan says，"To give people a guilt﹣free option that they can wear without someone throwing paint on them ﹣ I think that's going to be a massive thing，at least here in New York．" Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable．She's trying to come up with a label to attach to nutria fashions to show it is eco﹣friendly．
