"All Aboard" - Two New Invasive Species Per Year Entering US/Canadian Great Lakes


Somehow this posting was rejected by one of Lloyd's favorite sources, CuteOverload. Via Milwaukee Journal Sentinal: - "Frustrated by the mounting number of invasive species arriving in the bellies of overseas freighters, some conservationists are proposing a simple but radical solution: Ban the ships from the Great Lakes until they can figure out how to stop discharging contaminated ballast water. "This is being done out of frustration," said Jennifer Nalbone of the conservation group Great Lakes United. "This is a decision we've made because the federal government has failed to protect the Great Lakes."... New foreign species, meanwhile, continue to be discovered in the Great Lakes at a rate of about one every six months". Meanwhile, via The Detroit News, the global fleet also shows it's teeth: - "Shipping interests in the U.S. and Canada have banded together to try to strike down a Michigan law that attempts to stop the spread of invasive species such as zebra mussels into the Great Lakes. Four shipping companies, four shipping associations and one dock company filed a complaint in U.S. District Court in Detroit asking a judge to declare the Michigan Ballast Water Act unconstitutional." See earlier post on the environmental footprint of the marine shipping industry here. Besides supporting Great Lakes United, what can be done? Buy local.

NOAA Glossary Footnote: This author has had a Sea Lamprey attach briefly to his forearm. (Some say they'll let go of warm blooded animals on their own; but the natural response, which I share, is to yank it off with a free hand and get drunk in a failed attempt to forget it). Leaves a lasting impression about the significance of invasive species.
