问题     An invading species, the lionfish(狮子鱼)is completely destroying reef fish(珊瑚鱼)populations along the Florida coast and into the Caribbean. Now, an increasing number of environmentalists, consumer groups and scientists are seriously testing a novel solution to control it and other invading species growing in water— one that would also takes pressure off reducing ocean fish storage: they want Americans to step up to their plates and start eating invading creatures in large numbers.
    Invading species have become an annoying problem in the United States. With few natural predators(天敌)in North America,isuch fast-breeding species have thrived in American waters, eating native creatures and out-competing them for food and home.
    While most invading species are not commonly regarded as edible(可食用的)food, that is mostly a matter of marketing.experts say."We think there could be a real market." said Wenonah Hauter.the executive director of Food and Water Watch.whose 2011 Smart Seafood Guide recommends for the first time that diners seek out invading species as a "safer, more sustainable" alternative to their more decreasing relatives, to encourage fisherman and markets to provide them."What these species need now is a better profile, and more cooks who know how to use them, " she said. She has enlisted famous chefs to promote eating the creatures.
    Scientists emphasize that human consumption is only part of what is needed to control invading species and restore native fish populations, and that a comprehensive plan must include restoring fish predators and erecting physical barriers to prevent further spreading of the invaders.
    "We are not going to be able to just eat our way out of the invading species problem." said Philip Kramer, director of the Caribbean program for the Nature Conservancy. "On the other hand, there are places where this can be a very useful part of the strategy."
    Of course, there are also risks to stimulate America’s appetite. Marketing an invading species could make it so popular that individuals would raise or release the fish where they did not already exist.potentially worsening the problem.
