Health experts say handwashing is the single most important thing you can do to reduce your chance of getting sick or making other people sick. But as Rebecca Williams reports, recent research finds antibacterial soap is not any better than plain soap at keeping us from getting sick. And some scientists and doctors worry there might be risks to widespread use of antibacterial products:

Some studies estimate about 70% of liquid soaps on store shelves have antibacterial ingredients in them. Ingredients such as a chemical called triclosan.

Allison Aiello teaches epidemiology at the University of Michigan School of Public Health. Aiello is lead author of a paper in the journal Clinical Infectious Diseases.

She examined more than two dozen studies on antibacterial soaps containing triclosan. She says triclosan kills bacteria by going after the bacterium’s cell wall.

“The cell wall cannot be kept intact anymore; it’s not able to survive.”

But Aiello says there’s a growing body of evidence that even though antibacterial soap kills bacteria, it’s no better than regular soap at preventing illness.

Regular soap doesn’t kill bacteria, but Aiello says it works just as well at getting rid of bacteria and viruses like swine flu.

“Regular soap, is basically, it has a surfactant in it and what it does is it allows bacteria to be dislodged from hands and then the motion that you’re using under water helps dislodge it and make it go down the drain, basically.”

Aiello says it’s important to note that the soap studies were done with basically healthy people.

She says more research needs to be done to find out if antibacterial soaps could be more effective for elderly people or people with compromised immune systems.

But Aiello says generally, for healthy people, antibacterial soaps are no better than plain soaps at keeping you healthy.

And she says there could be risks to antibacterial products. She says there’s evidence from lab studies that antibacterial soaps might be adding to the emergence of super-bugs: bacteria that are resistant to antibiotics.

“In the laboratory setting, it is clear that there are mechanisms that can lead to antibiotic resistance when bacteria are exposed to triclosan.”

Aiello says they haven’t seen this play out for antibacterial soaps in the real world yet. But she says researchers need to keep an eye on it because antibiotic resistance might take some time to develop.

The soap industry dismisses the idea that antibacterial soaps might have something to do with antibiotic resistance.

Brian Sansoni is with the Soap and Detergent Association.

“The last thing we want to see is people discouraged from using beneficial products. Antibacterial soaps have proven benefits, they’re used safely and effectively by millions of people every day. Consumers should continue to use these products with confidence.”

The Food and Drug Administration has the final word on antibacterial soaps. But they’re still trying to figure out what to say about them.

The FDA has been trying to come up with rules for the products for more than 30 years. Right now there are no formal rules about the levels of antibacterial chemicals in soaps. And there aren’t any rules about how the products can be marketed or labeled.

There’s one thing both the soap industry and doctors agree on – Americans don’t wash up often enough with any kind of soap.

A recent study found one out of every three men walk out of the bathroom without washing their hands. Women did better than the guys, but still, about one of every ten women didn’t wash their hands either.

Experts say after you sneeze, cough or visit the restroom, you should scrub your hands with soap and water for 20 to 30 seconds.

That’s as long as it takes to sing the happy birthday song twice.

Saving With a Smart Grid

The government is spending billions of taxpayer dollars on a new “smart grid.” Mark Brush reports the new grid could eventually save you money on your energy bills:

Right now – power just goes from point A to point B.

But with a smart
grid system, your house can talk back to you and the power station.

The
meter could tell you how much it costs to heat your water, for instance.

And the power company will be able to talk to you if they’re having a
problem.

So, if they’re headed for a blackout, they can text message you
or e-mail you and ask you to shut off your A/C.

Jesse Berst is the founding editor of Smart Grid News dot com. It’s a trade publication.

He says, if electric grids are updated across the country, it would cut
down on pollution and save money.

“And that means there’s billions, tens of billions of dollars of power
plants and lines that we wouldn’t have to build over the next couple of
decades.”

Upgrading the system won’t be easy.

Each state has regulatory agencies that oversee thousands of electric
suppliers.

So there will have to be a lot of coordination.

The Mass Transit Paradox

So with the government’s 787 billion dollar stimulus plan now approved, a lot of folks in state and local government are thinking about the federal dollars that’ll float their way soon. Some mayors are especially eyeing the 8.4 billion for public transit. Rene Gutel looks at who wants to spend what:


Mayors from coast to coast see the stimulus package as one big pot of gold. Phoenix mayor Phil Gordon knows exactly how he’d like transit money spent in his city.


“First and foremost, Light rail.”


(sound of a train)


It’s all about light rail. Phoenix is notorious for its car-culture, freeways and gridlock; Residents worry it’s turning into the next L.A., but a brand new twenty-mile light rail line launched in December.


Trouble is, it’s only one line. It goes from the suburb of Mesa and ends in downtown Phoenix.

Mayor Gordon wants to use federal stimulus money to add a three-mile extension. Gordon says it’s the ultimate shovel-ready project. All planned, just add 250-million dollars and it’s ready to go.


“We could sign a contract with America, with the federal government, that we will turn dirt by March 31st, and we’ll create 7,000 new jobs.”


Those new jobs will be around long enough at least to get the rail extension built. But getting a light rail line is not the same as keeping it running.

Look at San Francisco that has a well developed transit system. They have a different kind of wish list that centers on maintaining the system they already have.

Judson True is a spokesman for the San Francisco Municipal Transportation Agency.


“We want to repair light rail vehicles that have been damaged in collisions, we have some cable car kiosks that we’d like to replace, we have change machines we’d like to replace in our metro subway stations.”


And it keeps on going. The American Public Transportation Association has identified nearly 800 public transit projects nationwide ready-to-go within 90 days.

APTA says the projects will not only create hundreds of thousands of jobs, but reduce fuel consumption and decrease greenhouse gas emissions.

But San Francisco’s Judson True says, while he’s grateful for funding for capitol projects…


“Systems like ours in San Francisco also need help on the operating side, and you see that all over the country.”


People are calling it the transit paradox and it’s hit cities like Denver, St. Louis and New York City.

Because of the down economy, ridership is up. And yet most transit systems rely on local and state money to subsidize operations. But with the economy flagging, cities and states are struggling too – and transit companies are having to cut routes and raise fares.


“You have a catch 22, more riders and you have to make service cuts.”


That’s Aaron Golub, an assistant professor in the School of Planning at Arizona State University. Mass transit’s his specialty. He’s worried about transit systems getting gleaming new buses, and kiosks, and buildings but then not having the means to operate them.


“It would be quite ironic if, for example, Phoenix were able to afford a light rail extension while cutting back on light rail service at the same time. Or the worst case, opening a light rail extension and not being able to operate it at all.”


Golub points to studies that say you create more jobs by investing in current transit operations – not capitol projects.

But many mayors across the nation feel light rail and other mass transit is an investment in their future. They’re ready to take on those shovel ready projects now with the hope that it’ll kick start the economy now and by the time the routes are finished, we’ll be out of the recession.

Interview: Keeping Alien Invaders Out

  • Asian Carp is one species that is very dangerous to the Great Lakes ecosystem (Photo courtesy of the US Fish and Wildlife Service)

Nature never made a connection between the nation’s big rivers and the Great Lakes. But Chicago did. A canal was dug connecting the Mississippi River system – including the Missouri, the Ohio and all their tributaries – to all of the Great Lakes at a point on Lake Michigan. It opened up commercial shipping to the interior of the nation.
But it also opened up both bodies of waters to aquatic life you don’t want traveling back and forth. Invasive species such as the zebra mussel have traveled from one to the other. Asian Carp have already caused havoc in the Mississippi. Some biologists worry the Asian Carp will destroy the four-billion dollar fishing industry in the Great Lakes if it gets in. There’s an electric barrier in place, but some people don’t think that’s enough.

Nature never made a connection between the nation’s big rivers and the Great Lakes. But Chicago did. A canal was dug connecting the Mississippi River system – including the Missouri, the Ohio and all their tributaries – to all of the Great Lakes at a point on Lake Michigan. It opened up commercial shipping to the interior of the nation. But it also opened up both bodies of waters to aquatic life you don’t want traveling back and forth. Invasive species such as the zebra mussel have traveled from one to the other. Asian Carp have already caused havoc in the Mississippi. Some biologists worry the Asian Carp will destroy the four-billion dollar fishing industry in the Great Lakes if it gets in. There’s an electric barrier in place, but some people don’t think that’s enough. Joel Brammeier is with the environmental group Alliance for the Great Lakes. His group is proposing a barrier that will separate the Mississippi system from the Great Lakes completely, to stop those invasive species. He talked with Lester Graham about the barrier:

Joel Brammeier: Well, ecological separation means no species moving between
the Mississippi River and the Great Lakes. When you consider the problem of
invasive species, unlike chemical pollution, which you can reduce to a certain
safe level, there is no safe level of invasive species. Once two get in, they can
reproduce, and the damage is done, and there’s no going back. So, an
ecological separation means stopping fish, and eggs, and other critters from
moving back and forth between the two systems.

Lester Graham: How do you do that when there’s so much commercial traffic
and recreational boating, and just the water flowing through?

Brammeier: Well, in our research, we found that tech fixes – electrical barriers,
sound barriers, blowing bubbles through the water to try and deter fish from
moving – those things can reduce the risk. But for invasive species, risk
reduction really isn’t enough – you need 100% protection. And to do that, we’re
probably looking at some physical barrier that prevents water and live organisms
from moving between those two great watersheds.

Graham: I can imagine the commercial shippers are not thrilled about that.

Brammeier: Well, I think it remains to be seen. Nobody’s quite sure where the
best place is to put a barrier. We discussed about half a dozen different
scenarios under which you could implement that kind of separation. The
Chicago waterway system does support about 25 million tons, give or take, a
year of commercial commodity traffic – and that’s a significant amount. The
reality is that most of that cargo is internal to the Chicago waterways. So, there
isn’t a huge exchange of cargo between the Chicago waterway and the Great
Lakes. And that’s a good thing. That means we have opportunities to actually
split the system back to the way it historically was, and at the same time, solve
our invasive species problem.

Graham: Now, we can see how that would benefit the environment, but how
would it affect the economy?

Brammeier: Well, again, going back to this issue of commercial navigation. If we
create a separation in this system that has a minimal impact on most of the cargo
in the Chicago waterway, we’re really talking about potentially a very small
impact. And, frankly, there’s an opportunity here to create a benefit for
commodity movements as well. A lot of the cargo transfer facilities on the south
side of Chicago are outmoded, outdated, and not competitive. And, any
investment in this kind of project that changed that and also allowed cargo to
move more efficiently and created new port facilities, could have that kind of
benefit, besides protecting the Great Lakes from invasive species.

Video Games Shoot Up Energy Bills

Transcript

People across the country are firing up one of their favorite gifts they got from the holidays – video games. Mark Brush reports on some surprising results about what home video games can do to your energy bill:

Video games are a quick escape into an alternate reality… (snd up) fortunately with multiple lives.

(snd of gunfire)

There’s a war going on in this basement.

Taurus and his partner Walt are using their M-16s, grenades, and knives to fight off the enemy.

(snd)

In real life – Taurus is Will Frey.

He’s a sophomore at Michigan State University.

And he’s been working really hard on his overall ranking:

“So I am currently seven hundred and eleven thousandth”

That sounds really bad.

But actually it’s really good.

He’s better than more than 5 million other people playing Call of Duty 4 on their Xbox consoles.

It’s estimated that forty percent of U-S Households have a video game.

And that number is growing.

The games are played for hours and hours – but they’re also left on – even if nobody’s playing them:

“A lot of sports games – you can’t save in the middle of a game – and the games are like usually a half an hour, so if you’re like twenty minutes and you have to leave, you don’t want to lose that twenty minutes kind of thing you know.”

Frey says he has friends that leave their games on all the time.

They never shut them off.

Some don’t want to lose their progress in a game, and some, he says, are just plain lazy.

The Natural Resources Defense Council says some game designers overlook the energy footprint of these things.

They added up the energy used by all the gamers in the country in a year’s time. And found it roughly equals the juice drawn by a big US city in one year.

The report’s authors compared the energy used by the three most popular gaming consoles.

And the big energy winner was the Nintendo Wii.

It uses about 8 times less energy than Sony’s Playstation 3 or Microsoft’s Xbox 360.

That’s because the Wii doesn’t have the same kind of high end graphics and sound as the Xbox and Playstation – those take a lot more power to run.

Nick Zigelbaum is an energy analyst with the NRDC.

He says the games should be designed better:

“What people don’t realize is that video game consoles, although they’re very similar to laptops and computers in terms of hardware, they don’t go to sleep or go into idle mode like a computer would.”

Zigelbaum says the power hungry XBOX and Playstation games do have an autoshutdown option.

That means the games will automatically turn off if nobody’s using them.

But the games are shipped with the option turned off.

You have to manually set it.

And not all games are equal.

For some games it’s easy to save your progress – for others…
you might lose your spot in that twenty four hour car race.

Zigelbaum says that’s where the industry needs to step in:

“That’s the issue is that it’s not really standardized, it’s not really uniform throughout the whole software industry. So it would be difficult to really implement a strong auto-shutdown feature.”

Zigelbaum says a strong auto-shutdown feature would be the biggest improvement game makers could make.

That would mean no matter what – your game would be saved when the device shuts down.

If the industry did that – homeowners could save more than 100 bucks a year on their energy bills.

A Microsoft spokesperson said they encourage their users to turn the games off when they’re done.

Zigelbaum and the folks at the NRDC are hoping Microsoft and Sony will go farther – and do a better job when designing their next gaming consoles.

(snd)

Will Frey says his friends don’t really think about the energy they use.

How could you when you’ve got other things to worry about?

“Oh my gosh! That’s why the M-4 is the cheapest gun in the game. Next to LMGs.”

(snd)

That stands for “Light Machine Guns.”

Maybe next year’s gaming consoles will shoot holes in the amount of energy they use up.

Every year there are about 1.5 million
deer-car accidents. Now highway officials are
testing a new system to cut down on those
accidents. Rebecca Williams has more:

There are some animal detection systems that use lasers or infrared motion
sensors. But those systems can be tripped by tumbleweeds or small animals.

In Colorado, highway officials are testing a new device.

Nancy Shanks is with the Colorado Department of Transportation. She says
they’ve buried cables along each side of the highway. The cables emit an
electromagnetic field. When an animal crosses a cable a warning sign with a
picture of a jumping deer lights up.

“It will detect a change in the field to the tune of a large animal. The system
will not pick up a smaller animal – a skunk or a rabbit, mouse.”

This cable system isn’t cheap. The pilot project costs 1.2 million dollars.

But Shanks says if this system works out, the price should come down a bit
over time.

15th ANNIVERSARY OF WATER CRISIS

Fifteen years ago, 400,000
people got sick and more than 100 died
from contaminated drinking water. It’s
still the biggest outbreak of waterborne
disease ever in the United States. It
happened because a parasite got into the
water supply in Milwaukee. Since then,
there have been major changes in water
systems across the nation. Erin Toner
reports:

Dr. Ian Gilson has been treating AIDS patients for 25 years. He says in all that time,
nothing’s been as bad as 1993 when Milwaukee’s drinking water was contaminated with
a parasite called cryptosporidium.

“We began to get reports of some of our patients having diarrhea that didn’t stop and we
had patients with weird stuff like an ulcer that was not related to acid, severe gall bladder
disease without stones. Ultimately by the time it was called a waterborne epidemic we
knew we had a big problem on our hands.”

Healthy people who drank the water, or brushed their teeth with it, or ate food that was
washed in it, had severe vomiting and diarrhea. But people with weak immune systems,
like those HIV with AIDS, couldn’t fight the parasite. And there weren’t good AIDS
drugs back then, so the patients just deteriorated.

“I distinctly remember several patients saying if you can’t get me over this let’s just be
done with this. One guy who was suffering terribly, we couldn’t seem to get him enough
morphine. And I ordered what I thought was a fatal dose of morphine because I thought
that was the only thing that was going to help him. And it actually relieved his pain.”

When it was all over, cryptosporidium killed 103 people with HIV and AIDS. Even after
15 years, the source of the parasite is still a mystery.

“The cause is not known and may never be known. There does not seem to be any
obvious explanation.”

Carrie Lewis is superintendent of Milwaukee Water Works. She says at the time of the
outbreak, the city pumped in water through an intake pipe about a mile off shore in Lake
Michigan.

The prevailing theory is that sewage overflows contaminated water in the bay, and that
the water was pushed toward the intake pipe and entered the treatment plant.

Lewis doesn’t buy it.

She says if human sewage was the source, people would have had to be sick to excrete
the parasite, and there’s no evidence of that. Some also speculate that cow manure
contaminated area rivers, but Lewis says regular testing in the watershed rarely finds
traces of cryptosporidium.

Lewis says she has no clue what happened, and she’s OK with that. She says what’s
important is what’s changed since then. Lewis says water testing at the time of the
outbreak amounted to taking a couple of samples a day – and that was considered good.

“Today we have hundreds of instruments testing the water every single second for all
sorts of different parameters, so the 15 years that’s gone by it’s a lifetime.”

The cryptosporidium outbreak so damaged Milwaukee’s psyche that people were willing
to do just about anything to make the water safe again. The city spent $90 million to
extend the intake pipe farther out in Lake Michigan. The filters at purification plants were
updated. And now the water is treated with ozone, which kills cryptosporidium.

What happened in Milwaukee caused changes around the country.

New federal regulations required water systems to test for the parasite and safeguard
against it. A drug was licensed to treat the disease.

Michael Beach is associate director for healthy water at the Centers for Disease Control
and Prevention. He says today people should have a lot of confidence when they turn on
their tap.

“Those types of outbreaks have virtually disappeared from the tracking system.”

Many water experts say municipal drinking water in this country is now the safest in the
world. They say the legacy of the Milwaukee outbreak is that water utilities are no longer
just managing a system of pipes and water mains – they’re in the business of protecting
public health.

A new report about the state of the nation’s ecosystems was recently released. And the results are so-so. Jennifer Guerra has the details:

Think of the report as the environmental equivalent of an annual physical exam.

Here are the results: the number of wetlands in the country is down and virtually every stream contains contaminants. On the plus side, it looks like soil erosion has decreased. And farmers are able to produce more food on less land.

Robin O’Malley plans to take those results to federal lawmakers. O’Malley is with the Heinz Center. It’s the non-partisan think tank responsible for the report.

“In the same way the chairmen of the federal reserve comes up and reports to congress about how our nation’s economy is doing, we think we need to do that kind of thing at a national scale for the environment.”

In addition to the report, the Heinz Center also included a little roadmap of sorts to help the lawmakers along.

Landscaping to Slow Runoff

Some cities are looking at taking away parking
on residential streets and replacing it with shallow
ditches full of native plants that filter stormwater.
It’s a way to reduce the polluted runoff that flows
into lakes, rivers and the ocean. As Ann Dornfeld
reports, not everyone is thrilled with the idea:

We’re walking down a winding lane lined with maple trees, tall, dry grasses and
evergreens. Bright white snowberries dot the dark branches. It feels like a walk
in the country. But we’re actually admiring a big-city sewer system.

This little valley – a sort of shallow ditch – is called a “bioswale.” Its plants filter
out pollutants that run off the street. And special, thirsty soil helps the water
absorb into the earth. Sections of the street are narrowed to make room for the
bioswales, so some parking along the street is lost. But houses without
driveways get two parking spaces between the swales.

The bioswales have thick layers of native grasses, shrubs and other plants. It’s
kind of a wild, natural look. Debbie Anderson lives on a nearby street. As she
walks by the bioswale she says to her it just looks messy.

“We think it looked nice when it was first built, but it hasn’t continued to
look good, I don’t think. We moved out here because there was no
sidewalks and the streets were wide open and we like that. Lots of parking,
we can have lots of company. This way you can have, what, two people
that can come? That’s it! No. I don’t want it.”

That’s a pretty familiar argument to Bob Spencer. He’s with the City of Seattle’s
Public Utilities office.

“The big thing is the lack of parking. People really get into using these
street right-of-way shoulders as their personal parking spots.”

But not everybody thinks parking spots are more important than doing something
to reduce water pollution. Spencer says the neighbors on this street actually
competed with other blocks to get these bioswales. It’s free landscaping – and
the city even worked with each homeowner to choose plants that would blend
with their existing garden.

Spencer says the city’s traditional method of dealing with stormwater has washed
contaminants into a nearby creek.

“Well, in the surrounding streets around here, we have what’s called ‘gutter
and ditch’ drainage. And what happens is the water runs off the property
and the impervious streets and rooftops. And it enters a ditch and then
goes pell-mell screaming down to our local salmon-bearing creek, Piper’s
Creek.”

It’s not just Seattle’s creeks that are flooded with runoff. Untreated rainwater
flows straight into lakes and the ocean, polluting them. Cities across the country
are looking for ways to deal with toxic runoff like that.

Spencer says Seattle is pioneering
large-scale natural drainage. In other words, the rain is allowed to drain like it
does in the wilderness. The plant roots slow the water so it can absorb into the
earth. That helps prevent flooding. Pollutants like heavy metals, pesticides
and fertilizers are trapped in the soil, and some of them are broken down in these bioswales.

“So we’ve got a little bit more like a forested system in that we have a duff
layer that acts as a sponge.”

Spencer says the city hasn’t tested the water quality of the runoff that eventually
enters the creek. But he says the runoff has been slowed to a trickle.

“It infiltrates and holds and keeps here 99% of that runoff. So that’s a
pretty large flush of water that’s not entering the creek with this system.”

Officials in Seattle’s city government like the green look of the bioswales. And
they help the city meet federal pollution guidelines. City Council President
Richard Conlin says over the course of three bioswale projects, the city has been
able to lower the cost to about the same as conventional stormwater treatment.

Seattle’s newest bioswale system will be at the foot of Capitol Hill. That’s where
seemingly half of the city’s young people live, in blocks full of apartments,
nightclubs and parking lots.

“It’s actually the densest urban neighborhood west of Minneapolis and
north of San Francisco. So it has a lot of impervious surface.”

Stormwater from Capitol Hill rushes off the hard surfaces and down to a lake. So
the city is taking advantage of new development at the bottom of the hill. It’s
planning to filter the runoff through bioswales before it pollutes the lake.

“And once we’ve done that, I think we’re pretty much ready to say this is
the standard from now on.”

Conlin says the city will likely install bioswales in all new developments, and on
streets where the most runoff enters waterways.

He says cities around the country are contacting Seattle to find out how to install
bioswales of their own.

Indoor Shrimp Farming: A New Market?

Recently, shrimp surpassed tuna as the most-consumed seafood in the
United States. Most of the shrimp Americans eat is produced in
Southeast Asia, India, Mexico and Brazil. Russ Allen wants to change
that. He’s opened one of the world’s few indoor shrimp farms in the
Midwest. Allen says his operation meets an obvious market demand, is
good for the environment, and presents a new economic opportunity for
the country. The Great Lakes Radio Consortium’s Erin Toner reports:


In a big blue barn in Russ Allen’s backyard, there are thousands of
shrimp… beady-eyed, bacteria-munching, bottom-feeders.


Here, the life cycle of the shrimp starts in the breeding center, where
two big tanks of water mimic a place 150 feet deep off the shore of the
ocean where the water quality and temperature are stable. Allen says
it’s the perfect environment for shrimp to mate.


“Like in just about all animals the male chases the female, and they do a
little courtship dance, and then the male will deposit a spermatophore on
the female and when she spawns, the eggs pass through the
spermatophore, are fertilized and then go out into the water.”


A few months later, the shrimp end up in the production room where all
they do is eat, and sometimes, if they get excited or spooked, they jump
right out of their tanks.


“They don’t like light…”


“Oh (laughing)! Do you ever have them hit you as you’re standing
here?”


“Oh yeah, that’s why we have the nets up so they don’t jump.”


Russ Allen has been farming shrimp for three decades. He started in
Ecuador, and then went to Belize, where he started the country’s first
shrimp farms.


Allen and his wife moved back to Michigan in 1990, when he started
designing his indoor shrimp farm. It finally opened for business about a
year ago, and now, he’s selling all the shrimp he produces.


(Sound of shrimp market)


Allen says his indoor shrimp farm is one of the first of its kind in the
world. There’s no waste leaving his farm, so pollution’s not an issue,
and because there’s no water coming in or going out, there’s no danger
of introducing diseases into his system.


Allen says an indoor farm also moves shrimp farming away from fragile
coastal ecosystems. That’s where most of the industry has developed
around the world.


“In a place like the United States with all the development on the
coastline and land costs, you can’t really do it anywhere near the ocean
anyway. So, if you’re going to have a viable shrimp farming system in
the United States, you need to move it away from – you know – these coastal areas.”


But indoor farms haven’t always been a viable option, either.


In the 1980s, a handful of them opened in the U.S., including a big one in
Chicago. They all failed because the technology didn’t work quite right,
and because the cost of production made them unable to compete with
outdoor farms.


Bill More is a shrimp farming consultant and vice president of the
Aquaculture Certification Council. He says now, indoor shrimp farmers
have a better chance of making a go of it.


“Coming from third-world countries, there’s been a lot of issues with
illegal antibiotics being found in shrimp. There’s been environmental
and social issues that environmentalists have come down hard upon. It’s
sort of prompted the opportunity for a good indoor system where
you could manage those and you didn’t challenge the environment.”


But More says creating and maintaining a clean, organic indoor shrimp
farm is still very expensive, and it seems an even bigger problem now
that the price of shrimp is the lowest it’s been in a decade.


Shrimp farmer Russ Allen says he’s invested several million dollars in
his business. He’s the only guy in the game right now, which he
admits is good for business, but he doesn’t want it that way. He says
he’d like to see the industry grow in Michigan, and throughout the
country.


“In order to do that the government has got to be a partner in this, and
that has been the challenge… that when you don’t have an industry, you
don’t have lobbyists and nobody listens to you and you can’t get an
industry until they do listen to you. So, that’s been our real challenge
right now.”


Allen says he wants the government to offer tax breaks and other
financial assistance to the aquaculture industry like it does to other
sectors of the economy, but he says he can’t even get some local elected
officials to come and see his shrimp farm. He says with so many
companies moving jobs and factories overseas, he thinks government
leaders should be looking for ways to help new and perhaps
unconventional industries like his, grow.
