Drought



48 counties in Alabama and several counties in Georgia were declared natural
disaster areas in June because of the drought. By the end of August, the
Environmental Protection Division had issued a level one drought declaration
for the entire state, and several other southern states were declared in various
stages of drought conditions. Restricted water use, farmers eligible for
emergency loans. Record temperatures and little rain. Farmers and ranchers
in the plains states were talking about the 1930's dust bowl. Now, as then,
stunted corn stalks rattled in the fields, water holes were gone, and large herds
of cattle were sold off to save them from starvation.

Cane Creek is drying up. The music of running water is stilled. Long stretches
of rock and sand with only an occasional pool of water. It was like this four
years ago, but there were more and larger pools of water then. This is the
worst I've ever seen here. There were a few good rains in August; 24 hours
after the rain ended the ground would be dry, and I would be carrying water
to my little garden and small herb patch.

There is still a stretch of shallow water bordering my yard, but it was divided
into two parts in August, and now in September into three, with rocky barriers
between. One day in August as the water receded, I was in the back yard
when I heard a loud slapping sound. A fish had somehow flipped from the
water onto the dividing rocks. I wouldn't have believed that a fish no larger
than my hand could thrash about so vigorously and make so much noise. I
saved it by flipping it back into the water with a stick. But that fish and many
more will die as the drought continues. They are slowly being deprived of
oxygen, and they normally depend on bugs and debris washed in along with
run off from the rain for some of their food.

Four years ago, as the water sank lower and lower, big suckers over a
foot long lay gasping and dying in the shallows. I've seen no suckers that big
since, and now I'm not seeing even hand-size fish. The shallow stretch of
water along my back yard is covered with an ugly scum.
Buckie and I went walking in the dry creek bed, as we did four years ago.
It's the only time we can safely walk long distances through here during the
summer. We can see there are no snakes underfoot on this strange, rough
road.My walking stick was provided by the beavers. There were always
limbs and sticks floating down the creek, each neatly cut at an angle, peeled
clean of bark. I saved those that were straight and sturdy and of a comfortable
length.

The beavers have long been gone. Buckie ran about sniffing their caves.
I wished I'd brought along a flashlight so I could see how far they'd dug into
the creek bank. Only once have I seen the creek ice over, and then the ice
only lasted a couple of days, so they do not need to build winter lodges and
stockpile food as they do in the northern ponds.



Trees at the creek's edge sent their roots down through the water into the
bottom of the creek bed. Now these roots are exposed, gnarled and twisted.
Behind these roots are the beavers' caves. The odd lacework of roots reminds
me of burglar guards across a storefront. They wouldn't provide the beavers as
much protection as a burglar guard against their enemies, dogs and men, but
perhaps they made them feel more secure.

I wonder where the beavers are, and if they've even survived. I'd think they
would have headed for the nearest water, the Chattooga River, about 7 miles
away. It's still running, though very low. Bevers move clumsily on land.
They would have had to cross highways and fields near houses with dogs.
And the Chattooga River is polluted. The textile factory in the next town
has been fined several times by the EPA for releasing dyes and other wastes
into the river.

In one pool we pass, at least a dozen crayfish dart about. I usually only see
crayfish at night when I stand on the back deck and shine a light into the
water, catching them by surprise before they scuttle backward into the sand.
Also concealed in the sandy bottom in normal times are the mussels. I've
yet to see a live one, but I've often seen their shells, left by some creature
that savours their flesh. Now the empty shells are strewn through the rocks,
many so tiny they seem not worth the effort to open for the tiny morsel within.
Mussels don't seem to grow very large in this creek, the largest shell I've
seen is about 2 1/2-inches long. The shell linings that look like mother-of-pearl
are not as thick and lustrous as in the much larger shells I've taken from the
Tennessee River.

The bits of color in the woods to either side were leaves, gold and bronze
and crimson, turned and fallen two months before their time. Trees were
dying. Dead limbs littered the creek bed.

My attention was drawn to a pile of what looked at first to be rat droppings.
Poking them about with a stick, I discovered they were periwinkle shells, dusty
from dried mud, for they, too, spend much of their time buried, trying to stay
safe from predators. But one must have crouched here, sucking out their flesh
and then tossing the shells into this neat pile.

As to what feasted on the mussels and periwinkles, I can only guess.
Raccoons? Opossums? Or do coyotes roam the woods here, about two miles
north of my house. And I once saw a pair of muskrats swimming down the
creek at night. They were terrified of my light and swam quickly away to
hide. They could also have a taste for shellfish.

Walking down this rocky bed, I've never seen any Indian tools or artifacts.
Most of the rocks are dark and dull, indicating some iron content, or they
are sandstone, not the kind of stone for making arrowheads or tools. And
why should the Cherokees have camped long beside this creek, so
insignificant compared to other bodies of water not so far from here, the
Chickamauga Creek, the Tennessee River, and even the Chattooga River
when it ran clean and pure. And they did not always camp beside creeks
and rivers. I know of fields far from large bodies of water where spring
plowing never failed to turn up a few arrowheads and an occasional stone
tool. At least this was true several years ago.

Even though wading the occasional pool alleviated the heat, it was still too
hot for walking before late afternoon in August, so we could only wander
for about three miles or so up the creek before turning back if we were to
get home before dark.

Another afternoon I had planned to clean the kitchen, but the forecast was
for rain the next day. I thought it could be the first rain of many and the creek
would fill up again. It was four years ago when the creek dried up, and would
it be four years again before I could walk that rocky bed? And would I, when
four years older, be able to walk it?

I set the broom aside and pulled on my creek shoes. The rippled soles help me
to navigate the rocks, and the mesh tops drain out the water after I've waded.

This time we went down the creek, ending up within sight of a house, the first
one visible from the creek during our walks. Children were calling to one
another and someone had started a fire, I suppose for a cookout. The house
was some distance from the creek, but I felt like a trespasser, and we had
traveled our three miles or so.

Shortly before the house there is an underground stream that surfaces just
below the creek bank, filling the creek bed with cold, clear water. It was
only a few inches deep, but felt so good to my feet, cooling and refreshing
me. The evening air was thick with humidity from the impending rain.

Then the dry, rocky stretches all the way home. Here, as up the creek,
I was struck by the silent tragedy of countless deaths. All the tadpoles that
would never become frogs to serenade the summer evenings. There was
never a trace of the fish or the smaller water creatures such as the caddisflies.
The birds and the woods creatures must have feasted.

The polar ice cap is melting and polar bears are losing their homes. Here the
water world had vanished, and how would it affect the surrounding area.

Do not ask for whom the bell tolls..

It was getting dark. We had started out later than usual. Only an occasional
faint star shone through the clouds and there was no moon to light our way.
I was glad when the bridge suddenly loomed a few feet ahead, for under the
bridge and we would be beside our front yard and home.

After walking on sand and rocks, my feet felt as if they had been massaged.
I slept deeply that night and dreamed of running water where fish leaped
silvery in bright sunlight. That dream would be shattered many times in
the following days when I walked the dry creek bed again.

I started writing this in August. By the third week of September, although
we had rain and no longer had the blasting heat that dries up the rain soon
after it falls, the pools of water were noticeably smaller. There was no water
under the bridge. The creek bed had been dry at least a month longer than
it was four years ago. Then at last, during the fourth weekend of September
rain poured down and by Sunday afternoon the creek was filled with muddy,
flowing water. There is again the music of water rippling over rocks and
cascading over the edges of one rocky island that remains. We again have a
creek. The water will become clear in a few days and I will be wading again,
especially after a hot afternoon of yard work or grass cutting. There were
beavers in the creek again after the last drought. I wonder if they or some
of their offspring will come back this time.

Tiny But Terrible


The toilet was running and wouldn't stop. I rushed out to turn the water off,
grabbed the railing as I raced down the front steps. And cried out. Felt like
a red hot needle had been jammed into my hand. I went on to the side of the
house and turned off the water, Then came back to see what had stung me.

After I took its picture, I rubbed meat tenderizer into my reddened and
swelling palm. It took most of the pain away and helped prevent further
swelling and itching. Then I looked through my Field Guide to the Insects
of America North of Mexico, by Donald J. Borror and Richard E. White,
the Peterson Field Guide Series, 1970, Boston.

Saddleback Caterpillar (Sibine stimulea). All the time I have spent outdoors
and gardening and around trees and I had never seen one, never even heard
of them. One-inch long and its sting is worse than that of a wasp or yellow
jacket. I found more information on several gardening forums. People have
been stung from just brushing against them. I got an especially painful sting
I guess because I pressed it as I grabbed the rail. Some of the spines on its
back are filled with a poisonous venom. All one has to do is touch those
spines to be stung.

Here are some better pictures. Some of the gardeners, like me, had never
heard of the saddleback. One said it looked like a scottie dog. I think of the
pictures of thoroughbreds draped with cloth and the saddle on top of the
cloth. The adult is a drab little moth with dark fuzzy wings and body. The
larvae supposedly feed on tree leaves. This one must have dropped onto
the railing.

What a strange and beautiful creature. If I hadn't been stung, I might not
have noticed it, for I was so preoccupied with the water problem.

Them Bones Them Bones

Them Bones, Them Bones Gonna Rise Again

I just want mine to keep me upright for the remainder of my time above
ground. Judging from the results of recent tests, I think they might. I've just
viewed a chart that shows that bones inevitably "thin" or diminish in density
as one ages. Osteoporosis. Porous bones. Hunched backs and fractured
hips. Caucasian and Asian women are most at risk, as well as men who
have taken steroids.

A Dexa Scan last month shows I've actually increased the Bone Mineral
Density (BMD) in my spine- only by one-tenth-of-one-percent, but I think
any increase is significant.I would have been happy if the numbers had
stayed exactly the same as the first scan showed. But alas, they didn't.
The BMD loss in my left hip increased by -.9. (They didn't have a machine
that scanned both hips in 2004; this time they did.)

Bones change so slowly that Medicare will only pay for a Dexa Scan, also
known as a bone scan, every two years.The two scans I've had show that
I have osteopenia, which means some loss of BMD.

The doctor who ordered the scans prescribed Fosamax, a bisphosphonate,
which has increased bone mass in some people, but not all. After researching
osteopenia, osteoporosis, bisphosphonates, and trying to decipher the Dexa
Scan report, I've decided not to take the medication. I've learned that my
amount of BMD loss increases my risk of fracture by one-percent. Therefore
I don't think the even greater risk of known side-effects of bisphosphonates
is justified.

The University of Washington has an accessible course in bone physiology
which includes a lot of information on understanding the Dexa Scan and
on osteoporosis, including methods of prevention.

Here are my T-scores: Spine: -.9
Left Hip: -1.3
Right Hip: -1.2
My spine is considered "Normal", according to the technician who did the
scan, and according to material available on osteoporosis. T-Scores of +1
to -1 = normal; -1 to -2.5 =osteopenia; -2.5 and higher = osteoporosis.
The yardstick is the BMD of a 30-year-old woman.

So my hips are only -.4 and -.3 points higher in bone loss than my spine,
or those same amounts less than "normal".

Bisphosphonates have been linked to osteonecrosis of the jaw bone,
commonly called "Dead Jaw" and also "Rotting Jaw". A lawsuit was filed
against Merck, maker of Fosamax, in April in Florida. There are other
brand names of biophosphonates: Actonel, Boniva, Zometa, Aredia.
Many of those affected are cancer patients, some having received the
bisphosphonates by IV, and some receiving large doses.

A local pharmacist wrote that "the threat [of 'dead jaw'] is not nearly as
alarming as it might sound. About 94% of the reported cases...occurred
in patients with bone cancer...The incidence is much lower in patients who
take oral bisphosphonates. It's probably less than one case per 100,000
patients per year." And he urges "patients" to continue taking the drug "as
your physician ordered. The benefits probably outweigh the risks."
(Cook's Pharmacy advertisement in The Trion Facts, Wednesday, August
23, 2006)

Unlike Cook's Pharmacy, I find the threat alarming. I would feel more assured
by such a message if it were not from someone who profits from selling the
drug patients are urged to take. And by someone who didn't pepper the
message with the word "probably". I can do my own conjecturing: Probably
Cook's would not so blithely dismiss the risks of osteonecrosis if they or
someone close to them suffered from it.

Attorneys soliciting clients for further lawsuits claim a large percentage of
bisphosphonate-related jaw damage has gone unreported.

I am just as concerned by reports that bisphosphonates can and have caused
visual disturbances, aching joints, and that, if taken for ten years or more, can
actually cause bones to become more brittle and at increased risk of fractures.
But most disturbing of all is that it remains in the body and in the bones for ten
years after one ceases to consume it. Five or six years from now it may be
linked to more, and possibly even worse side effects, and the millions, mostly
women, who will have it in their bodies for years, will be able to do nothing
but wait to see if they will be inflicted with such horrors.

So no thanks, I'm not taking it.
I believe if I work harder at staving off osteoporosis that I can prevent
further BMD loss, or keep it at a very small amount. I believe some of
my BMD loss was caused by my curtailed mobility much of last year
because of sciatica and an injured foot. I stayed active and continued to
work out, but I didn't walk as much and I kept the weights lower on
the leg machines at the gym.

The two main weapons against osteoporosis are taking calcium and weight-
bearing exercise. Walking is a good weight-bearing exercise, but I don't
think it's enough. I'll keep lifting weights at the gym and, thanks to a
chiropractor's help, I'm no longer hampered by sciatica so I have for some
time been using heavier weights on the machines. I don't need to increase my
daily calcium intake, with supplements and dairy products I get enough. I do
need to never get so busy that I forget to take the supplements, so I've made
a note to myself to never skip a day. I also take magnesium. I have read many
articles about how magnesium and calcium need to be in balance, just as do
salt and potassium. Articles on the Magnesium Website show that a high
calcium intake without sufficient magnesium can cause many problems, and
that frequently what appears to be problems caused by a lack of calcium are
actually symptoms of magnesium deficiency.

Another article on the Magnesium Website claims that primitive man, with no
access to dairy products, did not consume a lot of calcium. Our bodies have
changed little since those times, but our diets have changed drastically. The
article implies that it is because of the low-calcium diet in ancient times that
our bodies store calcium. Magnesium, however, was plentiful from whole
grains and green leafy plants. And so, according to the article, primitive man
had a diet much higher in magnesium than in calcium. But we aren't told what
effect this magnesium-calcium balance had on his health, there's just the
implication that this is the natural way to eat. Other good sources of
magnesium are nuts and legumes.

Health care providers routinely tell women to take Tums as a source of
calcium. But reading the fine print on a Tums label shows that 1,000 mg
of calcium carbonate per tablet actually means only about 400 mg of
calcium, and no or very little magnesium.

Some other interesting things I've learned: the diuretic action of coffee
causes some calcium loss from the body. Yet a recent report shows the
value of coffee as an antioxidant and the amount of calcium lost because
of a cup of coffee can be replaced by drinking one-and-a-half tablespoons
of milk. Those who add milk to their coffee are safe.I've always liked mine
black. People who eat a lot of animal protein have denser bones and so do
people who are overweight. Weight loss can cause a loss in bone density.

So one could gobble up the meat, pack on the pounds, and have high
cholesterol and maybe heart disease and strained joints and whatever
other illness baggage that comes with obesity, but have great bones.

I think I'll stick to the plan I've been following, although I will
increase my magnesium intake. It'll be another two years before I have
another bone scan. The results then and any new information I've managed
to gather in the interim may send me back to the drawing board for a
revision.I do know that wellness is not totally a matter of luck: one has to
work at it. We have to learn about our bodies and take charge of our own
health.

At least I have the information that allows me to plan. Thousands of
postmenopausal women in their 40's and 50's without medical insurance or
with inadequate insurance do not. By the time they are able to get the medical
attention they need, many will already have developed osteoporosis and have
no choice but to take the risky bisphosphonates in an attempt to rebuild that
which they have lost. Here in the only industrialized country with no national
health insurance, that hundreds of thousands are broken and debilitated from
untreated illnesses is a national disgrace.

The charge for my last Dexa Scan was $379.00. The imaging facility had to
accept the reduced amount Medicare would pay, but those who do not qualify
for Medicare or who do not have adequate insurance would be responsible for
the full amount, as much as a third or more of the monthly wages of many
women who are already stretching each dollar as far as it will go.

When I went back to the clinic a few days ago for a mammogram I saw a
new sign at the desk. It stated that patients with no insurance must now pay
BEFORE they can see the doctor.

Giant Panda Baby

Lun Lun, one of the Giant Pandas at the Atlanta Zoo, has a new baby. This
is cause for rejoicing, for Giant Pandas are an endangered species, with only
about 1,600 in the wilds of China, about 200 in captivity worldwide.

The Giant Panda is a symbol of peace in China, and was once used on flags
to signal surrender. It is also the logo of the World Wide Fund for Nature
(also known as the World Wildlife Fund), an organization dedicated to the
conservation and protection of the world's endangered species.

I have mixed feelings about caged animals being displayed, but sometimes
it is necessary for perpetuation of the species. The less than 2,000 in
their native habitat are fragmented, with little communication between those
in separate areas. This means in-breeding and can cause future generations
to be susceptible to physical defects or disease.

The pair at the Atlanta Zoo are on loan-lease from China. Atlanta pays
$1.1 million annually in lease fees, and about another $1.6 million annually
for the maintenance of Lun Lun and her mate, Yang Yang, who were
brought to Atlanta in 1999 on a 10-year loan program.If the cub survives, it
too will belong to China. and will be returned there in 2 to 3 years. If it
survives, it will be only the 5th to be born and raised successfully in
the U.S.

The Atlanta Journal Constitution has provided a video of this unusual
birth. You may have to register to view it, but registration is free and will
enable you to read articles about the pandas. More videos and articles
about cooperation for education and conservation are available on the
Atlanta Zoo website .

Watching this video, one is struck by the wonderful instinct of this animal.
This was her first time to give birth. She was in labor for 35 hours. Lun Lun
weighs 237 pounds, the cub an estimated 4 ounces. (Zoo releases compare
its size to a stick of butter.) It was born September 6, blind and almost
hairless, but immediately after birth it can be heard squealing loudly. Lun Lun
picks it up, holds it gently in her powerful jaws, and retreats to a corner where
she nurses and cuddles it.

She is being watched around the clock by zoo staff who are ready to take the
baby if necessary, but so far Lun Lun has proven to be an excellent mother.
Let us hope the cub continues to thrive.
