Economic Growth
• an increase in the production and
consumption of goods and services
• typically expressed in terms of GDP
• facilitated by increasing:
–population
–per capita consumption

But, for the sake of wildlife conservation, it’s not
enough to hope we’re a
K-selected economy.

The Big Hope

The Great Debate: Is There a Limit?
“Yes”• Physiocrats
• Classical economists
• Ecological economists
• Ecologists
“No”• Neoclassical
economists
• Corporations
• Politicians
![Page 28: Economic Growth as the Limiting Factor for Wildlife Conservation Including Considerations of Technological Progress.](https://reader030.fdocuments.us/reader030/viewer/2022033101/56649d9e5503460f94a87c24/html5/thumbnails/28.jpg)
Why would there not be a limit?
• Substitutability of resources
• Increasing productive efficiency
• Increasing human capital
![Page 29: Economic Growth as the Limiting Factor for Wildlife Conservation Including Considerations of Technological Progress.](https://reader030.fdocuments.us/reader030/viewer/2022033101/56649d9e5503460f94a87c24/html5/thumbnails/29.jpg)
White Pine, “Big Wheel”
![Page 30: Economic Growth as the Limiting Factor for Wildlife Conservation Including Considerations of Technological Progress.](https://reader030.fdocuments.us/reader030/viewer/2022033101/56649d9e5503460f94a87c24/html5/thumbnails/30.jpg)
Substituting for white pine,
employing more efficient
technology.

Why would there be a limit?
• Carrying capacity
• Thermodynamics
• Trophic levels

Carrying Capacity

Thermodynamics
• Fixed amount of matter
• Entropy
• Fixed amount of energy

Clear to All
• Without technological progress,
GNP limited
• GNP growth faster than
technological progress = trouble

Unclear to Many
• Technological progress: raising the
bar or accelerating the approach?
• Does technological progress occur
without increased consumption?

The “Information” Economy
But just ask 2 questions:• What is the information
used for?
• How does one come to
afford the information?
![Page 46: Economic Growth as the Limiting Factor for Wildlife Conservation Including Considerations of Technological Progress.](https://reader030.fdocuments.us/reader030/viewer/2022033101/56649d9e5503460f94a87c24/html5/thumbnails/46.jpg)
To say that an economy may grow perpetually on a finite land mass is to say that a stable economy may occupy a perpetually diminishing land mass!

Real Questions
• What is the limit?
• How do we know when we’re approaching the limit?
• What do we do to prevent breaching the limit?

And yet we hear:“Some people just don’t get it. There is
no conflict between economic growth
and environmental protection!”
Why do they persist?
