The Environmental Protection Agency EPA and the states (usually that state's agriculture office) register or license pesticides for use in the United States. EPA receives its authority to register pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Ask the EPA to apply the precautionary principle when approving any poison for use in and around freshwater. Remind the EPA that Rotenone and Antimycin A kill much more than target species, including nontarget fish, amphibians, and important macroinvertebrates, many of which never fully recover.

Write a letter to the editor of any publication that runs an article about the use of Rotenone or Antimycin A for the removal of nonnative fish, including, and especially, your local paper. The editorial page is one of the most important sections of any newspaper. More people read the "Letters to the Editor" section than any other section. This is an ideal forum for conveying your message about river killing. Not sure how to get started? Earthjustice has a great list of tips on their website titled, "How can I write an effective letter to the editor?" Go!
