The soda-pop you drink, the
t-shirt you wear, the cooking
oil you use – all might contain
genetically engineered material.
Lester Graham reports on a
continuing trend in agriculture:

The U.S. Department of Agriculture reports, this past year, 88% of cotton, 91% of soybeans and 85% of the corn crops planted were genetically altered.

That means corn syrup, cotton cloth, and hydrogenated soybean oil are all more than likely are from genetically engineered crops.

Margaret Mellon is with the Union of Concerned Scientists. She says farmers might embrace them, but genetically engineered crops have not really advanced American agriculture that much.

“I’m not saying there are not benefits, but they’re really modest. In particular, I think it’s important to note that it really hasn’t had an impact on yield – which is what we need if we’re going to increase the amount of food in the world and feed more people.”

The makers of genetically engineered seeds, companies such as Monsanto, say their crops do increase yields by stopping weeds and insect damage. The big bio-tech companies say their crops save farmers money, mean fewer harmful pesticides and reduce soil erosion.

Americans’ waistlines have been
expanding for decades. But new
research suggests at the same time,
more and more food is going to waste.
Shawn Allee reports:

On average, Americans weigh 20 pounds more than they did back in 1974.

But Kevin Hall found there’s more to the story. He studies nutrition at the National Institute of Diabetes and Digestive and Kidney Diseases.

Hall’s research revealed we produce more food to keep up with our bigger appetites, but he also found we’re wasting more.

“We were kinda shocked to see that the rate of increase of food supply was greater than the rate of increase of food consumption we calculated. Somewhere along the supply chain from the farm to the dinner table, that food was wasted.”

Kevin Hall estimates well more than one third of our food production goes to waste.

He says it’s not clear who’s to blame, but someone should find out because food production uses a lot of water and fuel.

The ethanol industry and the government
want more ethanol to be produced. They
say the homegrown biofuel is a good way
to move away from foreign oil. But a new
government report says many ethanol
refineries are putting a strain on another
natural resource – water. Mark Brush has
more:

When you fuel up at the pump, chances are you’re putting ethanol into your car. Nearly half of the gasoline in the U.S. is blended with ethanol. And that’s likely to increase as they build more refineries.

But the Government Accountability Office says these ethanol refineries should consider local water resources before they build. It can take a lot of water to make ethanol.

Anu Mittel follows water resource issues for the Government Accountability Office:

“Many of them are being built in areas where they are relying on groundwater aquifers for their water supply and that could have a devastating effect on the local community that is also relying on that same water source for all of its other needs.”

Refineries built in those areas often rely on irrigated corn to make ethanol. So it means drawing millions of gallons of water just to make the ethanol at the refinery.

And millions of gallons more to grown the corn.

Fuel From Abandoned Fruit

Every year in the US, more than 750-
million pounds of watermelon rot away
in the fields. Those left behind can’t
be sold because they’re sunburnt, diseased
or damaged, but now scientists in Oklahoma
are working on a way to use the abandoned
fruit. Gail Banzet reports:

Growers say it was a pretty fair season for watermelons in 2009. A lot of ripe, juicy
melons were enjoyed during the summer months, but, every year, 20% of the crop
never makes it to buyers.

(sound of driving)

Research chemist Wayne Fish steers his truck around the USDA’s agriculture research
laboratory in Lane, Oklahoma.

There are 320 acres of different crops and vegetables here, and one acre is dedicated
to watermelons. Workers have already picked the good ones. Those that are left are
discolored, misshapen or damaged by raccoons or birds.

“There’s one where a crow has pecked on it. That melon is over-ripe, so it has
two strikes against it.”

But Wayne Fish says that watermelon can still be used.

“It’ll still make ethanol fine.”

Four years ago, the National Watermelon Association started studying the ethanol
potential of watermelon sugars. When the project showed favorable results, a trial
process began at the research station in Oklahoma. Bob Morrissey is Executive Director
of the National Watermelon Association.

“If you’ve got that fully developed watermelon there, it has all of the components
– the water, the sugar and the fiber – to create ethanol.”

(sound of machines in a lab room)

Back at the research station in a lab, Wayne Fish and his team combine yeast with
watermelon sugars. Hours later, the mixture is fermented and placed in a still.

“By distilling that mixture, one drives the ethanol off together with a small
amount of water. That’s how we enrich the mixture to ultimately 95% ethanol.”

Fish says the project is not an attempt to replace sugar cane or corn for ethanol. This
pilot phase of testing shows wasted watermelons can add some ethanol to the overall
market.

Bob Morrissey at the National Watermelon Association says using the melons could
open up a whole new market for farmers. They could sell the good ones to people and
the bad ones to ethanol plants.

“That farmer could literally harvest his or her entire crop, send it to the ethanol
plant, and at least get something out of it to try and cover their cost instead of
taking a complete loss.”

There are a lot of growers across the country who are worried about wasting melons.

Jim Motes is from Oklahoma. Even though he’s not a huge farmer, he says he’s always
looking for ways to make the most of his crop.

“If they can find a large enough quantity to make it efficient, then it’s a good idea,
because there are a lot of watermelons laying there when the field disked up that
ought to find some use.”

Researchers say watermelon ethanol is drawing a lot of attention. A Texas-based
company Common Sense Agriculture is currently working on a mobile unit that would
process the melon sugars and produce ethanol right in the field.

Atrazine in Our Water

People have been concerned

People have been concerned
about farm chemicals getting
into drinking water supplies
for a long time. A recent report
showed that the chemical atrazine
peaks, in many areas, in concentrations
much higher than previously thought.
Julie Grant reports there are
things you can do to protect your
family. But, finding out if you
have a problem is harder:

Bob Denges is worried. His water is discolored. So he’s
called a water purification company to test it.

(sound of running water)

They’re running water in the basement utility sink. It’s kind
of orange-y looking. So, it’s an easy diagnosis: too much
iron.

“You can probably see in the toilet, upstairs just on the first
floor, that there’s some brownish, reddish discoloration
around the toilets.”

That’s not great. But at least you can tell when there’s iron
in the water. You cannot see or taste other water
contaminants such as weed killers like atrazine.

Tom Bruusema is the water filter expert at the National
Sanitation Foundation. They test and certify water filtration
devices. He says the first place you can check is your local
municipality – the folks that monitor water in your area.

“That would be the place to start. They are required, by
federal law, to measure a number of contaminants, produce
an annual report for their consumers.”

But recently an investigative report by the New York Times
revealed water contamination can spike in some places –
and local water officials might not even know about it.

That weed killer – atrazine – is applied on farm fields and, in a
lot of places, you also find a lot of atrazine in the water
during that time.

If you’re looking for it at the right time.

Sometimes it spikes for longer than a month. But some local
water officials only test for atrazine once a month, or only
once a year, and often it’s not during that peak application
season.

So people can’t really find out about atrazine levels for their
drinking water in those places.

Some water systems are spending lots of money to treat
drinking water to get atrazine levels down to what the federal
government considers safe levels.

But that might not be enough, according to some of the new
scientific evidence about atrazine.

Five studies published in peer-reviewed journals recently
have found evidence suggesting that small amounts of
atrazine in drinking water causes health problems. Even at
levels considered safe by federal standards, atrazine might
be associated with birth defects. Things like low birth
weights in newborns. Skull and facial malformations and
misshapen limbs.

Forty-three water systems in six states — Illinois, Indiana,
Iowa, Kansas, Mississippi and Ohio — recently sued
atrazine’s manufacturers. They want to force the company
Syngenta and its partner Growmark to pay for removing the
chemical from drinking water.

Steve Tillery is an attorney in the lawsuit.

“Some of them have gone to the expense to cleaning it
completely out of their water supplies, so that it doesn’t exist
at all. And they should, in our view, be entitled to
reimbursement of expenses for cleaning it completely out of
their water supplies.”

But, some water systems are not cleaning out atrazine
completely. And, as we mentioned, there are times when
some don’t know they exceed the federal safe drinking water
levels.

There is something pretty easy you can do if you’re worried
about your water.

Tom Bruusema of the National Sanitation Foundation says a
simple carbon filter can remove atrazine. Those are the
filters you can attach to the faucet or the pitchers you refill.

“So it’s a good investment. Certainly can help them if they
have those kinds of concerns, and particularly those living in
an area that’s known to have potential contaminants in the
water supply.”

But first people have to be aware of a possible problem.
And, too often, they are not.

The Attractiveness of Ethanol

  • The government will soon decide whether to allow increasing the mix from the current 10% blend to as high as a 15% blend. (Photo courtesy of the National Renewable Energy Laboratory)

Cheap oil makes switching to alternative
fuels such as ethanol less attractive.
Lester Graham reports that could affect
an upcoming decision about using more
ethanol:

Crude oil prices spiked a little because of Iran’s long-range missile testing and revelations of a secret nuclear facility.

But analysts think for the next several months we’ll actually see oil prices go down – maybe to around $30 a barrel, less than half of what it is now.

And that could hurt demand for fuels such as ethanol.

But the government has mandated the nation produce more ethanol.

Dan Flynn is an analyst with the trading firm, Alaron.

“Obviously the government definitely wants to push this through. However, the price of crude oil and gasoline, if that goes down, generally people look not to look for alternative sources of energy.”

One way to use more ethanol is to mix higher amounts with gasoline.

The government will soon decide whether to allow increasing the mix from the current 10% blend to as high as a 15% blend.

Sampling a New Crop: Sugar Corn

The federal government wants more
and more ethanol in our fuel supplies,
but it worries about how its made.
Most American ethanol is made from
corn kernels. That’s inefficient
and it makes the ethanol and food
industries compete for corn. The
government’s mandating we start making
ethanol out of things other than corn
kernels. Shawn Allee looks
at one effort to meet that mandate:

I’m just outside an ethanol plant in central Indiana and its pretty much like most ethanol
plants. There’re a lot of semi-trucks going by and they’re loaded with yellow corn kernels.


Most ethanol plants grind corn kernels for starch, they let that starch turn into sugar, then
they brew the sugary juice into ethanol. Now, this whole process would be easier and
cheaper if we could make ethanol directly from sugary plants instead of starchy grain
kernels like corn.


Pretty quick here, I’m gonna meet a guy who’s trying to make corn a plant that’s easy to
grow in the Midwest but produces sweet juice – not starchy corn kernels.

“If you walk over here, these are our sugar corn hybrids.”

I’m with Todd Krone. He’s a researcher with a company called Targeted Growth. He walks me
through a test plot of a plant nicknamed ‘Sugarcorn.’ He pulls off a ear of corn and pulls back the
leaves.

(sound of leaves being pulled back)

The ear is almost bare.

Allee: “There’re just a few stray kernels developing, very few.”

Krone: “Yep. A few got through.”

Krone says this plant avoids making corn kernels. Instead, it puts energy and sugar into the
stalk. He can prove it with a taste test – right here in field.

He snips a piece of stalk.

(sound of snipping)

And pulls out a little press.

Krone: “You squeeze some of the juice to see how much sugar’s there. It’s up to you, if
you like, you could put on on your finger and taste. Is there sweetness?”

Allee: “Yeah, it’s definitely sweet. It’s definitely got a sweet tinge to it.”

Krone: “It might be a bit sweeter than pop might be.”

Krone says tests show Sugarcorn juice is as sweet as juice from sugar cane. He says this means
America could have a new plant that boosts ethanol production – but doesn’t compete with food,
and uses equipment farmers already have.

Krone: “For the farmer, not much changes until harvest when some logistics still need to
be worked out.”

Allee: “Obviously if you’re selling a lot of this corn, you’d be making a good deal of profit,
hopefully, what’s in it for the rest of us in terms of the success or failure of this, for drivers
and everybody else?”

Krone: “I would say, hopefully, it results in cheaper ethanol that can compete with cheap
oil. And then meeting that mandate to get more and more ethanol produced.”

Well, that’s the idea, but Targeted Growth would have to change more than just corn plants to
succeed. They’de have to change how at least some ethanol companies do business. And some
ethanol companies have some tough questions about it.

“How could you handle sugarcorn? How would you store it?”

This is Jeff Harts. He works at Central Indiana Ethanol. Harts says he likes the idea of using
sweet corn juice to make ethanol – it could be efficient. But he worries about getting enough to
run an expensive operation like his. He has no problem finding corn kernels.

“It’s a consistent flow of corn and we need that consistent flow to keep going. That’s why
we have storage, the farmers have storage. That’s why we have a local grain elevator
network to ship corn to us to keep that flow steady 12 months out of the year.”

Harts’ company might be a bit reluctant to change right away, but ethanol producers will have
find alternatives to the corn kernel. The government is capping how much ethanol can come
from corn starch.

As those requirements phase in, alternatives like Sugarcorn might look sweeter than they do
now.

Keeping the Breadbasket From Drying Up

Right now, America’s Bread Basket
relies on an aquifer that’s nearly
drained. And, many say, it will dry
up if farmers keep pumping water
from it at the current rate. Devin

to pay farmers as one way to get them
to cut water use:

Right now, America’s Bread Basket
relies on an aquifer that’s nearly
drained. And, many say, it will dry
up if farmers keep pumping water
from it at the current rate. Devin
Browne reports the government plans
to pay farmers as one way to get them
to cut water use:

Bob Price is every bit the Heartland farmer. He’s dressed head-to-toe in denim with a belt
buckle the size of a small plate. Just like his neighbors, he grows thirsty plants like corn
and alfalfa. But, the land is so dry and so sandy that many agricultural experts think it’s
not suitable for farming.

When Price moved to Southwestern Kansas in 1973, it didn’t seem to matter that the land
was so dry. In his pick-up, on the way to his farm, he tells me that it was the beginning
of an irrigation boom.

“Out here everyone was getting up early, going to work, and all along Highway 50 it was
irrigation pumps, irrigation pipe, engines; this was like a frontier back then.”

At that time, the government heavily subsidized the costs of irrigation. The farmers were
getting an almost immediate return. Their land appreciated almost overnight once
irrigation was established.

Farmers began to pump water – and lots of it – from one of the world’s largest
underground water supplies, the Ogallala Aquifer. They pumped two-feet of water for
every acre they farmed, right onto their crops.

“Meanwhile, the water table is declining and the water that we’re pumping is coming
from farther and farther down and, even with the same energy cost, it cost more to suck
water out of the ground from 500 feet.”

Last year, it cost Price more than $200,000 for the electricity to run the pumps to irrigate
about 900 acres of land. It’s one of the reasons he started to consider other options.

At the same time, the government, on both the state and federal level, started to think of
how to save the water left in the Ogallala Aquifer. Rivers were drying up and several
states in the Plains were suing or being sued for taking more water than they’re allowed.

Several states initiated water conservation programs as a response; Kansas was the first to
do it without the threat of a lawsuit. The program started in 2007. The strategy: pay
farmers to permanently retire their water rights.

Price had actually been wanting to take some of his land out of crops anyways. He’s a
prairie chicken enthusiast and he wants to start a guided hunting business. Prairie
chickens need prairie grass.

“So we’re farming one day, and we’re thinking, ‘sure would be nice to get that into
grass,’ but that’s an overwhelmingly expensive proposition.”

It’s not expensive to plant or grow prairie grass. You don’t need any irrigation for either.
But you do need irrigation for a cover crop that the farmers are required to grow for two
years before they can get to the grass. Susan Stover is with the Kansas Water Office.

“If we did not get something re-established there, we could have potentially dust storms
again and sand dunes moving and really big blow-outs.”

Blow-outs like Depression-Era, Dust Bowl blow-outs. So Price has to plant a cover crop
and pat double what he gets from the conservation program just to irrigate it.

Ironically, the government pays him sizeable subsidies to keep other land in corn, which
needs water from the aquifer to grow. So basically, one government program is paying
Price to stop using so much water, while, at the same time, other government programs
are paying him subsidies to grow the crops that need so much water.

Price would actually like more money to put the land back into grass, but if he wants to
lead hunting trips for prairie chickens and he wants prairie grass, there’s only one outfit
willing to pay him anything to plant that grass – the government.

There’s already a lot of genetically
modified corn and soybeans out there.
Now, Mark Brush reports, one company
is working on genetically modifying
trees:

The company is called ArborGen. And it’s working on altering Eucalyptus trees, so they can be turned into paper and biofuels more easily.

Eucalyptus is native to Australia and New Zealand.

But ArborGen has already got 330 acres of these genetically altered trees planted scattered across the South.

And now it wants the government to allow these trees to flower. And that has people like George Kimbrall worried.

He’s an attorney with the International Center for Technology Assessment. He says if they spread they’ll be bad for the environment.

“They’re water suckers. They don’t allow for much undergrowth. They’re poisonous to most animals. The leaves, the animals can’t eat them. Why would we want the south covered in Eucalyptus trees?”

When eucalyptus was brought over to California – it did become invasive. And there are some reports that it’s invasive in Florida too.

ArborGen says it’s altering these trees so they won’t spread in the wild.

Lawn Chemicals Cause Concern

New laws restrict pesticides and fertilizers in some cities. In recent years, farms have cut the use of chemicals. But, Rebecca Williams reports, some environmentalists say there are still far too many chemicals polluting streams and lakes:

There are 40 million acres of lawns and sports fields in the US. That’s only one-tenth of the amount of cropland.

But some experts say lawn pesticides and fertilizers can be more of a problem.

Charles Benbrook is the Chief Scientist with the Organic Center. It’s a non-profit research group in Oregon.

“While there are many more acres of corn and soybeans and cotton treated with pesticides than there are lawns, the rate of application on lawns in urban areas often is far higher than on the farm.”

And, he says people are more likely to get exposed to chemicals on lawns.

“There’s many more opportunities for significant exposures, particularly for children and pregnant women in urban areas.”

Nationwide, farms do use the bulk of chemicals. But Benbrook says homeowners are more likely to overuse pesticides and fertilizers.
