This could happen anywhere in the world, and probably is. The transportation industry has been responsible for the spread and movement of a great many things.

Experts gather in D.C. to examine invasive species
KNIGHT RIDDER/TRIBUNE
. MILWAUKEE ?- The problem of invasive species flooding into the Great Lakes via the St. Lawrence Seaway is now drawing the attention of some of America's top scientific minds.
The National Academy of Sciences on Tuesday will convene a committee of transportation, economic and environmental experts to explore ways to stanch the flow of unwanted creatures into the world's largest freshwater system, while at the same time enhancing global trade in the region.
T
he Great Lakes are home to at least 180 foreign species and a new one is discovered, on average, every six and a half months. The overwhelming majority of the invaders since the 1970s, including the quagga and zebra mussel and the round goby, made their way into the lakes in the belly of overseas freighters carrying contaminated ballast water.
Ballast water, often taken on at one port and dumped at another, is used to stabilize a ship on the high seas.
The shipping industry acknowledges the problem, and the race is on to develop a technology that will decontaminate ships' ballast water tanks.
But some members of the shipping industry are already suspicious of this new Academy study, which is funded by a grant from the Great Lakes Protection Fund, a nonprofit corporation established by the Great Lakes states governors to finance projects to improve the environmental health of the region.
Steve Fisher, executive director of the American Great Lakes Ports Association, says now is the time to press on with ballast treatment research, instead of spending $850,000 to take a sweeping look at the way the Seaway operates.
"These dollars could probably be better put to use in helping join with all the others who are looking at shipboard treatment systems, to help find the technology that needs to be developed to solve this problem," said Fisher, who will attend the meeting as a representative of the shipping industry.
