That's an interesting application of economic ideology to biological 
systems.  There was a guy named Lysenko who tried the same thing in the
USSR with disappointing results. 
While the biology is complex, I suspect the ones that survive and 
prosper under overfishing will be the ones of little economic value
and/or whose reproductive cycle isn't disrupted as much by over-fishing.
These *efficient* fish will be, by definition, less valuable to us.

You may be right, but I think that the analogy with the potato is
strained. Most increases in agricultural production have been as much
from the availability of cheap fossil fuel energy as from technology.
And there's little relationship between the technology required to 
increase potato productivity and implement a productive fish farming
culture. Leaving aside the use of non-renewable energy, the efficient 
conversion of solar energy into food by either means depends on factors
unique to each, I think. 
  As an example, let me quote some statistics on

Assuming it isn't counteracted by a decline in the availability of

Actually "health" is subjective.  More accurately it reflects the 
role of economic efficiency in determining farm numbers, and they
are certainly that, although I would argue that they aren't particularly
efficient users of resources, due to flaws in the way our economic
system prices non-renewable energy.

Are you sure?  Global food stocks are said to be the lowest in recent 
history. Of course we may be creating a system where we are keeping
very low inventories while food production rises fast, so I won't argue 
the point.

This is where it is useful to go into the moral and religious
literature of western civilization. The morality can be considered
either a religious mandate, or a societal evolution. I believe it is
both. Up until recently, there was an american identity which included
certain moral values, regardless of what institutions those americans
were involved with.
With the arrogant, nihilistic and hedonistic values "revolution" of
the last 30 years, we have had people suddenly feeling free to make up
their own morals. The result is the screwed up and degenerate society
we have today.

There is no topsoil whatsoever in Central Arizona and yet they manage
to grow a wide variety of crops there. I have seen grain fields there,
although in general grains are not economic.

Well, Xe-134, when it absorbs a neutron, becomes Xe-135,
which can decay into Cs-135.  However, their plan was to dissolve
the fuel as the fluoride in molten FLiBe, so the Xe can be removed
online by helium sparging (a very fast process).  This means the Xe134
will not be transmuted to any significant extent to Xe-135 (the
neutron capture cross section is low anyway).  It does mean that the
Xe-135 that is produced as a fission product will mostly decay
after it has been removed from the reactor, so one gets most
of that Cs-135 already separated from the other Cs isotopes.
If Xe-135 is left in a reactor, btw, much of it gets transmuted before
it decays (its thermal neutron cross section is around 2 million
barns.)  So one might want to sparge the xenon, then feed it back
into the reactor as a compressed gas in a separate loop.
>You just cannot control which reactions you get.
Sure you can: by separating out the isotopes to be transmuted
(when this is economical) and putting them back into the high
flux part of the system.  You can't get reactions on the things
you don't put back in.

The producer price index for "finished goods" is a reasonable measure 
of constant dollars.  The price of fish has increased by 66% relative
to other goods.  In another post, I present the price of fish 
relative to the more common CPI (which includes services too).  The
price of fish has increased 40% relative to that.  
This is consistent with the theory that it's getting harder to
increase the supply of fish, or even maintain it at a constant 
level.
: Susin's mistake was speculating that the technological trends for fish 
: were the same as those for chicken.  The fish caught today are 
: genetically the same as those caught in the 1930s.  This is not true 
: of chicken.
I'll take your word for it that technology has marched ahead faster 
in raising chickens than in catching fish.  But recall that McCarthy
originally claimed, in essence, that techological progress was
slower in fishing than in the _average_ industry.  He hasn't 
proved this point either.
Here's what McCarthy wrote:
: 2. The relative increase in the price of fish is related to the fact
: that the productivity of fishing hasn't increased as much as the
: productivity of other industries.  The price of a haircut has
: increased even faster relative to the CPI than has the price of fish,
: because the productivity of cutting hair has scarcely increased at
: all.
: 3. The demand for fish has increased, partly because of changes in
: taste and beliefs about health, but also because improved
: transportation has extended the market for fresh ocean fish into the
: center of the U.S.
From my layperson's perspective, it seems that technological progress
in fishing is pretty rapid (especially with all this stuff about
aquaculture people keep bringing up).  It's certainly faster than in
cutting hair, and probably faster than in construction, or education.
I admit that McCarthy's theory (slow technological change coupled with
an increase in the demand for fish) could theoretically explain the
increase in price.  But, in general, this explanation also predicts
that fish consumption per capita will go up.  This hasn't happened:
Fish Consumption per capita (lbs/year) 
1970   11.7
1980   12.4
1985   15.0
1990   15.0
1994   15.1
Fish consumption peaked in 1987, at 16.1 lbs/person/year.  Chicken
consumption, and even pork consumption have been increasing more
rapidly in the last decade or so.  
McCarthy could conceivably be right before 1987.  But since then, it's
hard to avoid the conclusion that we're hitting natural resource
constraints: fish are becoming harder to catch, and aquaculture isn't
compensating for it.

Stockman has proven a sore loser, and a revisionist. Once he realized
his policies weren't making it, he turned on his former compatriots
and turned loose a lot of accusations. How many are true? I don't
know, but the record indicates that the one you described above was
not.
The Reagan tax cuts were followed within about 2 years with net
INCREASES in tax revenue, as the supply siders said.

Patrick is taking my name in vain: the only transmutations I have

physical: 1.) Let stuff cool off for a while in pools; then 2.) dilute
it with rock, cement, glass or whatever is useful to make it easy to

I then suggest, lightly, that we drop it down old uranium mines -- but
I make this suggestion only for poetic effect: it came out of uranium
mines where it was doing no harm; why shouldn't it end up there once
it's been milked of some of its energy?
In practice I see nothing the matter with dropping it down holes
drilled in the Canadian shield, grinding it up and dropping it in the
ocean, or building pyramids with bricks of the stuff at Chernobyl.  I
do object strongly to the infinite expenditure of money on ever more
ludicrous and complex schemes which are of profit to nobody but the
usual suspects, Brown and Root, Bechtel, and all the other large and
very political contractors.
Radioactive waste is no more dangerous than dynamite.  A little bit
will kill you.  You have to be careful with it.  I propose that we be
very careful with it.  On the other hand it is not an evil magic, and
it seems to me extremely foolish to treat it as if it were.
Nuclear power has the very great virtues of being much cleaner than
oil, gas, or coal -- and it is almost evidence of a benificent
providence that we have stumbled across it at the very point where the
human race is reaching a large and stable population which will need
great quantities of energy to power an advanced civilization.
Seems to me we should be getting on with it.

How silly. Chernobyl has NOTHING to do with nuclear power in the US.
BTW, Chernobyl is turning out to have been a very useful (if
unfortunate) experiment. In spite of radiation dosage of a huge
population of people at far beyond the "acceptable safe limits," there
have been fewer than 50 deaths, all (but maybe one or two?) were
workers at chernobyl or disaster workers. Among children with very
high exposures, there have been a number of non-fatal,
non-debilitating thyroid problems.
Chicken little did a real number on us with that one.

I must vigorously disagree. A mandatory voting act means lots of
uninformed and uncaring people will be making the choices. The
curreent system selects for those who care enough to vote, and such
people are far more likely to be informed. To me, that is an much
better solution.
Of course, it would help us in your goal to bring us closer to the
society of the old USSR - they had mandatory voting also :-)

With growing frequency? Hardly. Corporations exercise very little
control in that regard.... the only exceptions I know of are medical
ones in a few cases (smoking, etc), control that I disagree with.
Look back in time and you will see vastly more control. EDS used to
interview the *spouse* of a candidate to see if she would fit
properly, for example. I'll bet they don't do that any more. Before
that were many single-company towns, where the companies had all sorts
of control.
Furthermore, you can flee a corporation. There are many alternatives.
You cannot flee the only alternative that is frequently discussed:
socialism, which has vastly more control.

Sometimes this is true, sometimes it is not. Many corporations these
days are much looser in that regard than in the past.
But consider: upper management must satisfy three constituencies:
stockholders, consumers and employees. They are hardly lords at the
top of the heap.

I do not quite understand this last point: why need
Simon "wriggle through"  merely because Heilig happens to

This is, *perhaps*, true - though there are some implications
of overregulation and social engineering in the above 
that might cause, not prevent, famine.
Setting that aside, and interpreting Heilig's
quoted text in the most benign way, there is still the
objection that he does not seem to distinguish
between *sufficient* conditions and *necessary* ones. 
Yes, if we did everything optimally, that would
work; but nothing has ever been optimal - 
yet we have got by, so far, and have progressed. 
There is no reason to think we can't progress
even faster, even if the problems Heilig
names remain unsolved.
There is a great pent-up capacity for food
production growth that has been dampened by a glut,
and can be released by increased demand.
This mechanism is sufficient, and it is in place.
A great majority of the world's farms do not use existing,
long existing, advanced methods: there is
a potential for doubling world food production right
there. New crop varieties have been designed
and tested but are not used yet: count it as another
doubling, more or less. And the genetic revolution (leaving
all else aside!) guarantees that still
other breakthroughs will occur. *Greater*
breakthroughs: since this technology is so new,
its future achievements are bound to exceed past ones....
Quite different directions of advance are possible:
e.g., hydroponics; or farming green algae in the ocean.
If this sounds not quite realistic, that
is for *one* reason only: lack of *demand*.
Conclusion: the question whether limits to
growth exist is academic. *If* they exist,
they are far, far, far away - not
worth practical consideration, because we can't see 
so far.

Actually, monopolies tend to grow less efficient over time (check out
your local phone company for an example). In free market theory, they
will then open up niches where competitors will appear and then grow
to compete at a large scale.
But my argument, that consolidation is normal, is not at all the same
as condoning monopoly. That is your construction.

It is the marketing board that creates the monopoly. Without it, you
have hundreds of autonomous farmers. Only through the use of
government coercion are they able to maintain control of their members
(Sunkist) in the face of market opportunity.

I think it is. But let's say it is not. I challenge you and others on

The price is not "set by the owner." The owner is coerced (to use your
wierd terminology) by both the producers of the food, the consumers,
and his stockholders. You may feel coerced if EVERY supermarket is
owned by a single company, but that only happens in small areas where
efficiency requires it.
 Your

Pirates use force... which is true coercion. Loan sharks may, in which
case they engage in coercion. But the supermarket owner does NOT use
any force whatsoever, so where is the coercion? I think you are
confusing freedom from coercion (culturally considered a right) with
choice (which is most definitely not a right, culturally or legally).

I want it lowered. It has cost me a lot of money, especially when I
received gains in uncontrolled lumps and then was taxed at brackets
higher than my normal income would indicate. But that's personal.
Have you ever wondered why almost every other first world country has
ZERO capital gains tax rate? 
Furthermore,  why would you want to raise the tax rate on savings
(capital gains taxes are taxes on savings for most people)? It is
alreadly over 50% for the average personr, who leaves money in capital
investments for a long time, because of the failure to index for
inflation. Fortunately for the economy, most person don't realize
this, or they would invest everything in tax free bonds or some such. 
So why do you want to penalize capital? It is employed to do
productive things.

No, I never said the proportion of income paid by the wealthy dropped.
But frankly, I think it should. As one gets more skilled and higher
paid, one's taxes paid go up exponentially (with the exception of a
social security pedestal). This is fair???
I think taxes ought to be a government fee... the same per person.
But for the less radical, maybe a person consumes more government
resources if they have a higher income (not true, but let's pretend),
then maybe they should pay a flat rate rather than a flat fee.
What the heck is wrong with that?
I think you simply want to punish the rich for being rich, regardless
of the iimpact on everyone else. That would be the result of the
policies you have pushed, on those few times when you made suggestions
rather than just pick at capitalism from a lofty pedestal.

That means his company received the fees, which is far different than
Ross personally ending up with all the money. Ross had all sorts of
costs, after all. He was a tough businessman, and maybe he shaved some
edges here or there, but I haven't seen that in this discussion. So
please explain, again, what is wrong with Ross Perot's company, or any
other company, getting a bunch of money from the government for doing
something that, at the time, NO ONE ELSE including the government,
could do?
Medixxx was a mandate on the states that did not give them time to set
up the capability to administer it. Ross, through very skilled
management, very hard work, and some luck, was able to do it. For
this, he is being attacked?
I have reasons to not like HR Perot, but that isn't one of them. As an
ex employee I was planning on suing him (reasons not to be discussed,
obviously), and was told to forget it - he could use his money to
crush me financially. That was unpleasant.
But he has done some very good things (I have seen the american flag
in his office signed by all the POWs who returned from Vietnam).

I never said they mismanaged in favor of the poor.
But you fail to appreciate the magnitude of these efforts. And the
profits were for work from MANY state governments, and other
businesses, and the billionaireness came from a stock market which
valued his company quite highly. It seems to me that you are just
slinging mud, without the information necessary to justify it.

There are always anomolies. But look at the numbers and you will see
the number of people flying is at a much higher level than before
deregulation. Some cities came out worse on deregulation, because the
fairs were being set at below market prices by regulation.
Furthermore, the development of the hub system, which made air travel
more efficient and affordable, may have caused some cities to have
higher prices.
So I am not denying your personal experiences. But they do not address
the whole picture.

Alright, now that we have called names.
What personal experience, and how was it relevant to the whole S&L;
issue over 15 years and 50 states?
 Do you deny that the tax law change of 1986 (elimination of passive
loss deductions) was the ultimate cause of the collapse? If so, do
what was the cause?
Do you deny that the deregulation under Carter and then Reagan was a
result of the financial insolvency of the S&L;'s in the face of
inflation and restrictive regulations?
Frankly, as far as I can tell, even my neighbor, the arch  fiend
Charlie Keating, would have paid back his creditors if he hadn't had
his business snatched out from under him at the last moment by the
regulators (who, I admit, were working for Reagan).

Speak of misleading!  Your table includes only the species that experienced
declines; not hard to support your thesis that 'fish are running out'. 
However, culling from the same source as you, the FAO, I pulled the
following data:
"World marine fisheries production has increased almost fivefold over the
past 40 years, rising from around 18 million tonnes to more than 86 million
tonnes by 1989... The use of fish as a source of food has increased
steadily, rising from 40 million tonnes in 1970 to 70 million tonnes in
1989."
"Five species accounted for most of the production increase during the
1980s. The catch of Alaska pollack, Chilean jack mackerel, Peruvian
anchoveta, Japanese pilchard and South American pilchard increased from 12
million tonnes in 1980 to 25 million in 1989.  The Japanese and South
American pilchard share with the Peruvian anchoveta the characteristic of
widely fluctuating yields as a result of natural variability. These stocks
are expected to decrease in the future. Indeed, Japan's catch of Japanese
pilchard dropped from 4.49 million tonnes in 1988 to 3.68 tonnes in 1990. 
"Catch has also increased for higher-value species which are facing
increased demand. The catch of all tuna increased fairly steadily during
the past two decades, adding one million tonnes to the total annual catch
between 1980 and 1989. The catch of skipjack and yellowfin tuna have
increased at a rate of 5.4 percent and 4.5 percent per year, respectively,
since 1970... There have, however, been recent increases in the catch of
albacore, particularly by Taiwan, Province of China, whose catch rose from
an average level of about 60 000 tonnes during the period 1977 - 1985 to
almost 140 000 tonnes in 1989"

Solar energy "hitting the earth" would be insufficient to meet global 
energy demands in the next century. Solar power stations on the earth's 
surface suffer from low efficiency due to cloud cover and the fact that 
they operate on a 50% duty cycle (year-round average).  So, as we see 
occasionally in the science magazines, a solar power station has to be 
built in outer space, orbiting the earth, and the energy beamed down by 
microwave. I don't know if this is acceptable to everyone, since it's 
obvious that this can also be used as a spaceborne weapon for frying 
targets on the ground.
A better alternative would be the wide use of fusion power, which burns 
heavy hydrogen, which is abundant in seawater (1 part in 5000, something 
like that).  There are two schemes, of magnetic and inertial 
confinement, but I think the latter would be impractical unless the 
efficiency of the confining lasers can be improved drastically.

If true, so what?  My point is basically that we're managing our
fisheries badly.  Even if fish farming can compensate for that,
that's no reason to screw up the oceans.
In any event, fish consumption per capita in the US, though higher
than in 1970, fell from 1987-1994.  And fish farming hasn't 
kept prices from rising 40% faster than inflation since 1970.

I think some probably are, but there is more to it than that, and the philosophy is

onto, and is not wholly appropriate.
> Do you necessarily oppose high-technology in all cases, or do you just want

All I want is to get general agreement that something is drastically wrong with the 
course we seem locked into. I don't have any neat 'solutions and don't believe I 
have a right to dictate solutions to 5 billion people. This is where I differ 
greatly from the mainstream. If we could all just agree on the problem first, 
without getting bogged down in solutions, we could get on with finding a better 
course. It often sounds like I'm opposed to any high tech, but this is because the 
high tech solutions put forward do not take into account the fundamental problems 
and amount to business as usual.
For example the'green revolution', which seems to just put off starvation for a 
generation or two as it turns huge areas into deserts. The genetic engineering that 
is going on now is just an extension of that. The science is subverted to the aims 
of big business before the scientists themselves have finished investigating what 
its potential uses and dangers are. We are being railroaded.
So I would like to see local solutions rather than global ones. This would involve 
the dismantling of all those power structures that cause uniformity to emerge where 
before there was variety. People can solve their problems without 'help' from the 
experts, if those problems are not compounded by outside exploitation. This is as 
true of farmers in the US corn belt who are being srewed and turned of the land by 
the banks just as much as those in the third world who grow cash crops for us 
instead of food and materials to improve their own lot.
> Do you support individual rights/libertarianism?
Absolutely, along with the responsibilities that go with it. Our network is made up 
of completely independent and autonomous local groups. There is consensus on certain 
things, for example whilst we don't (and can't) stop a fascist group from calling 
themselves EF! They would be completely ignored by the rest of the network and so 
would not have any succsess. Individuals in groups have an equal right to make 
suggestions and to say no to anything. There are no leaders, although some 
individuals do more than others, they have no more power over decisions.
> What's your approach to "value"; where does it come from?  Revelation?  Logic?

Don't know really, it's a personal opinion in the end. I believe that every organism 
is equally evolved and worthy of respect from a basis of love. This is not a popular 
concept and people always simplify it to "save the aids virus" or something like 
that. another example of the commonly held view being easy to argue from.

In this country the majority of MPs are also top corporation directors so the 
distinction is not really that useful. I think the main evil is our own profligate 
consumption, and blaming the directors is not helping. Thet are no more addicted to 
'progress' than we are. If I was in their situation I would be just as corrupt. It 
is true when people say it is human nature. I think we must have some kind of 
soultion that does not involve people being in such positions of great power.

The standard price of a man's haircut in Toronto has gone from $12 to
$10, or $8 with frequent discounts, in the last ten years.  This is a
drop of between 16 and 33%, and represents mainly the effect of
technological change introduced by the TopCuts people: training,
standardization of hair cutting subroutines, and store management.

Return to effort is measured with great accuracy in fishing, as in
mining or oil recovery, although I do't have that information.  You
are quite right that the marginal return in fish per cubic kilometer
of trawl, or whatever, is down.  At the same time the amount of
effective trawling s up -- and this represents dangers, as we have
seen with the Grand Banks cod fishery.
The good news is that political evolution is going on at a headlong
pace, and the laws, rules and practices surrounding fisheries are
changing in a blink of history's eye.

"Fish" says much less than the report I gave you in my earlier post
with the numbers I see on price tags at my local supermarket.  How
much of this 528% is catfish that has been marked up from slum offal
to yuppy delicacy?  When an oily bulk marckerel gets sliced inhalf and
dusted with file and labelled "Louisiana", the price goes from $1.75
to $11 a kilo, (which coincidentally is exactly your 528% increase).

My impression is that stocking of streams has been around for fifty
years in Japan and maybe thirty in the trout industry of the US Rocky
Mountain states.  Oysters, winkles, and other shellfish have been
farmed in Europe since the middle ages, but only on a large scale in
America for the last twenty years or so.  The stream salmon industry
in Canada is fifty years or more old, and maybe half that in Iceland,
Scotland and Norway.  Stockade-fed fish, however, is a brand-new
industry in the last eight or ten years, and is still accelerating,
and being applied to new breeds.  The creation of offshore reefs to
encourage fish-friendly environments is a comparatively new
development, and is also still growing in popularity.

Just a few thoughts inspired by lurking in this thread.
1. Lurking in a thread is uncomfortable.
2. Fishing in the oceans has undergone enormous technological
    advancement.  From poles - one fish at a time - to enormous
    seines that sweep miles of the ocean from great factory ships.
    A far greater technological advance than bigger chickens in
    bigger barns.  It was only a few decades ago that even tuna 
    were being caught by men with poles on the deck of the boat.
3. The posts in this thread are by people who do not play poker.
    Poker players know that there are two considerations, not 
    alone the ODDS.   Tbe other consideration in placing a bet 
    is the STAKE -- what might be lost as well as what might be
    won.    What is at stake in the limits to growth is life on the
    planet as we know it.  Should we play the game if the odds are 
    even 5000 to 1 that there is no limit in sight?   Think a moment.
    What odds are good enough?
4.  The acidity of the "no limits" posters is not buffered by 
     the fact that the worriers may have some points and may, by 
     their anti-Pollyanna program be a major factor in postponing
     the time of reckoning.
5.  Human nature is being ignored.  Human events in the daily
     papers are not instructing.  History is being forgotten.
     Consider the stress of population crowding --and there IS stress --   
     ask any New Yorker or read the experiments with rats and the
     observations of overcrowded zoo monkeys.  Consider the fact of
     tribal warfare (Bosnia, Rwanda, Azerbaijan, East Timor, Los Angeles).
     Consider the proclivity of humans to follow demagogues (Hitler, Milosovic,
     Mussolini, Napolean -- name your favorite).
     It is the nature of technologists to ignore human nature - at the peril
     of all of us.   In a world of ideal humans, resources would be shared fairly
     and without the need for warfare.  In a world of ideal humans, resources 
     would be developed timely for the need.  In a world of ideal humans, all 
     things would be possible.  That world does not exist.

Hey, it was McCarthy's example, not mine; and I'm sure he was 
cribbing it from Baumol or somebody.  I think I'm going to
vow never to say anything about technology again, except that
it can't be measured.

Your other post hasn't shown up in my newsfeed, which is having troubles,
I think.  
I think you're exactly right, though.  These figures understate the 
price increase.  The CPI (and the PPI too, I assume) changes the 
bundle of goods it measures, as people substitute away from 
things that are getting more expensive.  This is right for most 
purposes, but for measuring resource depletion, I think a 
fix-weighted index would be better.  And such an index would
surely show bigger price increases.

On reasoning like this we should stop wearing shirts because 200 plus
needleworkers died in the shirtwaist fire.  Many dozens of them died
by jumping out the windows as hundreds of people watched in the street
below, yet somehow scaremonger Nudds expects us to care more about
some statistically confected "probably" dead people.

I don't know what to say to this bit of repartee.  Let's just leave it

Both the UK and France operate reprocessing plants which have both
military and "civil" purposes.  And in the UK the weapons grade Pu has
certainly been produced in power reactors.
