Lieutenant general
Lieutenant general, lieutenant-general and similar is a three-star military rank used in many countries. The rank traces its origins to the Middle Ages, where the title of lieutenant general was held by the second in command on the battlefield, who was normally subordinate to a captain general.

What is the limit to growth?
The Limits to Growth ( LTG) is a 1972 report on the exponential economic and population growth with a finite supply of resources, studied by computer simulation. Commissioned by the Club of Rome, the findings of the study were first presented at international gatherings in Moscow and Rio de Janeiro in the summer of 1971.
Who published Limits to Growth?
Limits to Growth did not receive an official update in 2012, but one of its coauthors, Jørgen Randers, published a book, 2052: A Global Forecast for the Next Forty Years. In 2012, writing in American Scientist, Brian Hayes stated that the model is "more a polemical tool than a scientific instrument".
When was Beyond the Limits and The Limits to Growth: The 30-Year Update published?
Beyond the Limits and The Limits to Growth: The 30-Year Update were published in 1992 and 2004 respectively, and in 2012, a 40-year forecast from Jørgen Randers, one of the book's original authors, was published as 2052: A Global Forecast for the Next Forty Years.
Who wrote the report on limits to growth?
A popular analysis of the accuracy of the report by science writer Richard Heinberg was also published. In 2012, the Smithsonian Institution held a symposium entitled "Perspectives on Limits to Growth ".
What is the term for a real GDP increase?
Any increase in real GDP is called “economic growth ” even if it increases costs faster than benefits. Economists will note that the logic just employed is familiar in microeconomics — marginal cost equal to marginal benefit defines the optimal size of a microeconomic unit, be it a firm or household.
Why does GDP decrease as production grows?
As production (real GDP) grows, its marginal utility declines, because we satisfy our most important needs first. Likewise, the marginal disutilitiy inflicted by growth increases, because as the economy expands into the ecosphere we sacrifice our least important ecological services first (to the extent we know them). These rising costs and declining benefits of growth at the margin are depicted in the diagram below.
Is increasing production and consumption uneconomic growth?
From the graph it is evident that increasing production and consumption is rightly called economic growth only up to the economic limit. Beyond that point it becomes uneconomic growth because it increases costs by more than benefits, making us poorer, not richer. Unfortunately it seems that we perversely continue to call it economic growth! Indeed, you will not find the term “uneconomic growth” in any textbook in macroeconomics. Any increase in real GDP is called “economic growth” even if it increases costs faster than benefits.
Is there a limit to how much we can consume?
Even with no cost of production, there is a limit to how much we can consume and still enjoy it. There is a limit to how many goods we can enjoy in a given time period, as well as a limit to our stomachs and to the sensory capacity of our nervous systems.
Is macroeconomics the whole?
But the macro-economy is not the Whole. It too is a Part, a part of the larger natural economy, the ecosphere, and its growth does inflict opportunity costs on the finite Whole that must be counted. Ignoring this fact leads many economists to believe that growth in GDP could never be uneconomic.
Is the futility limit only for the poor?
In a world with considerable poverty, and in which the poor observe the rich apparently still enjoying their extra wealth, this futility limit is thought to be far away, not only for the poor, but for everyone. By its “non satiety” postulate neoclassical economics formally denies the concept of the futility limit.
When was Limits to Economic Growth by Brian Davey published?

Is there a debate about the limits to growth?
There is currently a fierce debate about whether these problems can be resolved – and there has been since the 1970s – from the very first time that the Limits to Growth book was published. At that time economists declared that the Limits to Growth authors had not understood how markets and technology worked and declared the study discredited. Nowadays, although a debate exists most mainstream economists and politicians seem to be barely, or not at all, aware of the issues and take for granted that growth can and should continue. In the last few years a few observers have noticed that growth in productivity is, in fact, slowing. They struggle to explain it.
Is it possible for the economy to grow for ever?
The academics concluded that sometime in the coming century growth would inevitably come to an end. It would not be possible for the economy to grow for ever on a finite planet.

What does "grow while growth is economic" mean?
Grow while growth is ‘economic’ (marginal benefits greater than marginal costs); cease to grow once growth becomes ‘uneconomic’ (marginal benefits less than marginal costs). Incredibly, when mainstream economists shift from microeconomics to macroeconomics – the latter involving the study of the national economy as a whole – the notion ...
What does economic growth mean?
In conventional terms, economic growth means either the growth in a nation’s real GDP (an increase in a nation’s output of goods and services) or the physical expansion of the nation’s economy (note: the two are not the same) (see Lawn, 2007a). So, when people refer to economic growth, what they really mean is either ‘growth ...
What is the optimality rule in microeconomics?
This optimality rule in microeconomics is applied to many other areas of microeconomics, such as the utility maximisation of consumers, determining the optimal labour supply decisions of individuals, and even determining the optimal choice between consumption and environmental quality.
Why is the increase in marginal benefits referred to as the principle of diminishing marginal benefits?
This is because an increase in its output would , under these circumstances, boost profits and thus be ‘economic’. At the same, one is taught in microeconomics that the increase in benefits gradually diminishes as you do more of the very thing that generates the benefits. This is referred to as the principle of ‘diminishing marginal benefits’.
What is the term for the study of individual markets and firms?
In microeconomics – the study of individual markets and firms – the term ‘economic’ implies that doing more of something has the effect of increasing benefits (marginal benefits) faster than it increases costs (marginal costs). Thus, in microeconomics, a firm is encouraged to increase its output if the ensuing marginal benefits – which exist in ...
What is the principle of diminishing marginal benefits?
One is also taught that the rise in costs gradually increases as you do more of the same thing. This is referred to as the principle of ‘increasing marginal costs’. Thus, while it is possible for a firm’s profit to rise as it increases its output, ...
Why do I support economic growth?
I support economic growth because: (1) as long as the net benefits of growth are equitably distributed, everyone is rendered better off; and (2) to be experiencing economic growth, the economy must be physically smaller than its maximum sustainable scale ( i.e., be at a physical scale that is biophysically sustainable).
Who warned about growth?
Carter warned about it, Reagan said growth was forever, Carter lost the POTUS election.
What is the measure of the physical size of the economy?
4) A surprisingly informative measure of the physical size of the economy is the amount of “useful work” created, which is defined as the product of energy availability and the efficiency of using that energy. There is an almost perfect correlation between energy and GDP, but useful work explains even more.
Is endless growth possible?
Endless growth is much more fun than a world with limits. Unfortunately, endless growth on a finite planet is impossible. As one scenario for the future they are planning for, advisors should include this when talking about what will happen.
Is innovation and technology the limits of economic growth?
Consistent with human experience over the last several centuries, conventional wisdom holds that innovation and technology have all but eliminated the limits to economic growth. But new scholarship – from outside the realm of traditional economics – contends that this is not true.

When do limiting populations become limiting?
they become limiting only when the population density reaches a certain level.
Do false populations build up again?
True/false populations never build up again after a crash in population size.
Overview
The Limits to Growth (LTG) is a 1972 report on the exponential economic and population growth with a finite supply of resources, studied by computer simulation. The study used the World3 computer model to simulate the consequence of interactions between the earth and human systems. The model was based on the work of Jay Forrester of MIT, as described in his book World …
Purpose
In commissioning the MIT team to undertake the project that resulted in LTG, the Club of Rome had three objectives:
1. Gain insights into the limits of our world system and the constraints it puts on human numbers and activity.
2. Identify and study the dominant elements, and their interactions, that influence the long-term behavior of world systems.
Methodology
The World3 model is based on five variables: "population, food production, industrialization, pollution, and consumption of nonrenewable natural resources". At the time of the study, all these variables were increasing and were assumed to continue to grow exponentially, while the ability of technology to increase resources grew only linearly. The authors intended to explore the possibility of a sustainable feedback pattern that would be achieved by altering growth trends a…
Conclusions
After reviewing their computer simulations, the research team came to the following conclusions:
If the present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity. It is possible to alter these gro…
Criticism
LTG provoked a wide range of responses, including immediate criticism.
Peter Passell and two co-authors published a 2 April 1972 article in the New York Times describing LTG as "an empty and misleading work ... best summarized ... as a rediscovery of the oldest maxim of computer science: Garbage In, Garbage Out". Passell found the study's simulation to be simplistic, while assigning little value to the role of technological progress in solving the pr…
Positive reviews
In a 2008 blog post, Ugo Bardi commented that "Although, by the 1990s LTG had become everyone's laughing stock, among some the LTG ideas are becoming again popular". Reading LTG for the first time in 2000, Matthew Simmons concluded his views on the report by saying, "In hindsight, The Club of Rometurned out to be right. We simply wasted 30 important years ignoring this work." Research from the University of Melbourne has found the book's forecasts are accura…
Legacy
The Club of Rome has persisted after The Limits of Growth and has generally provided comprehensive updates to the book every five years.
An independent retrospective on the public debate over The Limits to Growth concluded in 1978 that optimistic attitudes had won out, causing a general loss of momentum in the environmental movement. While summarizing a large nu…
