Testimony of the National Environmental Coalition on Invasive Species before the Senate Environment and Public Works Committee Hearing on the Importation of Exotic Species and the Impact on Public Health and Safety. Invasions by exotic plants, animals, and pathogens into non-native environments pose one of the most significant, but least addressed, threats to human health, agriculture and our natural ecosystems. Monkey pox, SARS and West Nile virus are the new buzzwords of public health, as communicable diseases increasingly leap hosts from animals to humans. In the United States, in 2002 alone, West Nile virus claimed more than 60 lives among constituencies represented by this committee and sickened more than a 1,000 people. Deliberate animal imports (legal or illegal) are thought to be one of the most likely ways that WNV got to New York City in 1999.
