Ten Threats: Hidden Costs of Invasives

In looking at these threats to the Great Lakes, almost everyone we surveyed agreed the worst threat was alien invasive species. Shipping goods in and out of the Great Lakes has helped build the major cities on the Lakes. But shipping from foreign ports has brought in unwanted pests. Zebra mussels are probably the most infamous, but there are more than 160 aquatic species that have invaded the Lakes and changed them, almost always for the worse. So why can’t we keep them out?

Today we begin an extensive series called “Ten Threats to the Great Lakes.” The Great Lakes Radio Consortium’s Lester Graham is our guide through this series:


In looking at these threats to the Great Lakes, almost everyone we surveyed agreed the worst threat was alien invasive species. Shipping goods in and out of the Great Lakes has helped build the major cities on the Lakes. But shipping from foreign ports has brought in unwanted pests. Zebra mussels are probably the most infamous, but there are more than 160 aquatic species that have invaded the Lakes and changed them, almost always for the worse. So why can’t we keep them out?


Well, let’s say I import widgets.


(Sound of widgets dropping into a cup)


I’ve been getting widgets from somewhere in Asia, but I found out I could get widgets from an eastern European company for a dollar-a-widget cheaper. The factory there can ship them directly to my warehouse in Great Lakes City, USA by ship across the Atlantic and into the Great Lakes.


Pretty good deal. I get good widgets, the shipping costs are cheaper, my profits go up, and it means cheaper widgets at the retail level. Everybody wins, right?


Well, the ship that brought the widgets also brought an alien invasive species that stowed away in the ship’s ballast. A critter that’s native to eastern European waters is now wreaking havoc on the Great Lakes ecosystem.


Aquatic alien invasive species that have invaded the Great Lakes now cost the economy an estimated five billion dollars a year. Five billion dollars of what’s considered biological pollution.


So, who’s paying the price?


Cameron Davis is with the environmental group Alliance for the Great Lakes.


“Unfortunately, in most instances, who pays for those hiddens costs are you and me. We pay for our water agencies to have to clean zebra mussels out of their pipes, we pay our agencies through taxes to have to keep Asian Carp out of the Chicago River, we pay through our taxes in any number of ways to try to fight these invaders.”


So right now, taxpayers and utility ratepayers – even those who never bought a widget and never will – are paying the price. Davis says that’s just not right.


“One of the things we need to do is make sure that those ships are paying full cost for everything that they bring, not just the widgets, but the stowaways like the zebra mussels, things like that that they have on board.”


So, why target the ships?


Dennis Schornack chairs the U.S. Sector of the International Joint Commission. The IJC is a bi-national agency that monitors a water quality agreement between the U.S. and Canada. Schornack says that’s the way it usually works: the polluters pay.


“The cost of the impact of these unwanted creatures is something that’s not baked into the price charged for the widgets. So, somewhere that external cost needs to be captured back into the price. The ship owners themselves are the likely target to pay for this through a permitting fee which, of course, they will pass on to their customers, the people who made the widgets.”


So all of us who buy widgets end up paying a little more, but paying permits and fees could cost shippers more than they can afford. George Kuper is with the Council of Great Lakes Industries. Kuper says he understands the first impulse is to make the shippers pay.


“The problem with that, of course, is the shippers were already close to non-economic as a method of transportation, which puts us right up against an environmental challenge because shipping is by far the most environmentally un-intrusive method of moving large amounts of materials.”


Kuper says using other methods of transportation such as trains or trucks to move that cargo from East Coast ports might burn more fuel and cause more pollution.


But of all the shipping on the Great Lakes, only six percent of the tonnage is carried on ocean-going vessels. The rest is transported on Great Lakes carriers that never leave the lakes and don’t bring in new invasives. So, the question is this: is that six percent of cargo worth the damage that aquatic invasive species cost each year.


Many experts say there is a fairly simple answer to all of this. Technology is available for cargo ships to eliminate invasives from their ballast tanks. Requiring those ships to use that technology would likely add some to the cost of every widget, but supporters of the idea say it would greatly reduce the environmental cost to the Lakes.

“24 Carrot” Farmers

According to the USDA, the number of farmers’ markets in the United States has increased nearly 80 percent in the past decade, with roughly 3,100 in operation.

According to the USDA, the number of farmers’ markets in the United States has
increased nearly 80 percent in the past decade, with roughly 3,100 in operation. Like
many other Midwesterners, Great Lakes Radio Consortium commentator Julia King buys
much of her warm-weather produce from local growers. But King thinks those farmers
grow something else that might be just as important as food…


Not long ago, my ten-year-old daughter gathered her allowance, dropped her coins into a
see-through, polka-dot plastic purse and journeyed with me to our local farmers’ market.
Inside the old warehouse-turned-emporium, we strolled up and down the aisles. She
sniffed bars of soap and fragrant candles, poked bags of cheese bread and gazed at
almond croissants. But it was a large butternut squash that finally caught her eye.


She smiled and pointed at the unusual treasure. The farmer behind the counter called out
a price and I watched from a distance as she dug into her little plastic purse, pulling out a
quarter here, a dime there. As she calculated the numbers, her smile faded; she was fifty
cents shy of the total.


“Oh, you go ahead and take it anyway,” he told her. “It’s a little bit old, really.”


She paused, uncertain. I stepped into view and offered a dollar to the farmer, but he
stood his ground. He wanted to sell the squash to my daughter for the price she could
afford. He said it was a fair exchange. We thanked him repeatedly and my daughter took
the big pear-shaped vegetable in her arms like it was a baby doll.


It was not the first time one of the market’s farmers had put kindness before cash. Shop
there long enough and someone is bound to say, “Oh, take two, they’re small” or “This
one’s a little bruised; I’ll throw it in for free.”


These aren’t “blue light specials” or “supersaver sales;” they’re gifts from people who
never tire of the magic that springs from the earth. In a year of Saturdays, I’ve been
invited to marvel at the shape of a carrot, to behold the size of a potato, to delight in the
beauty of a snapdragon.


In a nation of box stores and billionaire wannabes, a nation where “excess” is master, the
men and women who labor in the soil offer a glimpse of something different. It’s a
commerce measured not only by what they gain, but also by what they give.


John Greenleaf Whittier put it best in his poem, “Song of Harvest”:


Give fools their gold, and knaves their power;
Let fortune’s bubbles rise and fall;
Who sows a field, or trains a flower,
Or plants a tree, is more than all.
