Biodiversity: Invasive Species Multiply in U.S. Waterways http://apocadocs.com/s.pl?1262713707
The U.N. says some experts put the rate at which species are disappearing at 1,000 times the natural rate, and invasive species -- which consume the food or habitat of native species, or the native species themselves -- are one factor contributing to this acceleration. Climate change is another major factor.
"Often it will be the combination of climate change and [invasive] pests operating together that will wipe species out," says Tim Low of the Australia-based Invasive Species Council.
The International Union for Conservation of Nature says that 38 percent of the 44,838 species catalogued on its Red List are "threatened with extinction" -- and at least 40 percent of all animal extinctions for which the cause is known are the result of invasive species.
