6
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
7
K GNP Time Natural capital allocated to wildlife Natural capital
human economy Time Czech, B Economic growth as the limiting factor for wildlife conservation. Wildlife Society Bulletin 28(1):4-14.

Some Empirical Evidence:
Causes of Species Endangerment as a “Who’s Who” of the American Economy
9
Endangerment Causes Urbanization Agriculture
Water diversions (e.g., reservoirs) Recreation, tourism development Pollution Domestic livestock, ranching 247 205 160 148 143 136 Czech et al Bioscience 50(7):
10
Causes (cont.) Mineral, gas, oil extraction Non-native species Harvest
Modified fire regimes Road construction/maintenance Industrial development 134 115 101 83 81 Czech et al Bioscience 50(7):

Making sense of the Who’s Who with
Trophic Theory

Economy of Nature Super- Carnivores Service Providers Consumers Producers (i.e., plants)
13
Producers (i.e., agriculture, extraction)
Human Economy Light manufacturing Heavy manufacturing Service Sectors Producers (i.e., agriculture, extraction)

22
K and r-selected Economies
23
American GNP, K or r-selected?
24
But, for the sake of biodiversity conservation, it’s not enough to hope
we are K-selected.
25
Wildlife Conservation and
Steady State Economy K To conserve wildlife... GNP ...maintain steady state economy sufficiently below K. Time
26
But what about Technological Progress?
27
Technological Progress
Vernacular: invention, innovation Technical: increasing productive efficiency resulting from invention and innovation
28
KU KT Natural Capital Allocation Revisited GNP Time
X natural capital allocable KT Natural capital allocated to non-human economy GNP Natural capital allocated to human economy Time
29
The Big Hope KU GNP Time K2 K1 Economic growth with technology level 2
X natural capital remains allocable K2 X/2 conserved K1 Economic growth with technology level 2 GNP Economic growth with technology level 1 Time
30
The Great Debate: Is There a Limit?
“Yes” Physiocrats Classical economists Ecological economists Ecologists “No” Neoclassical economists Corporations Politicians
31
Why would there not be a limit?
Substitutability of resources Increasing productive efficiency Increasing human capital
32
White Pine, “Big Wheel”
33
Substituting for white pine, employing more efficient technology.

35
Why would there be a limit?
Carrying capacity Thermodynamics Trophic levels
36
Carrying Capacity Consumers Products Byproducts
37
Thermodynamics Fixed amount of matter Entropy Fixed amount of energy
38
Another look at trophic levels, this time in light of thermodynamics.

Economy of Nature Biomass/100 Service Providers Biomass/10 Biomass
40
Producers (i.e., agriculture, extraction)
Human Economy Light manufacturing Heavy manufacturing Service Sectors Producers (i.e., agriculture, extraction)
41
Clear to All Without technological progress, GNP limited
GNP growth faster than technological progress = trouble
42
Unclear to Many Technological progress: raising the bar or accelerating the approach? Does technological progress occur without increased consumption?
43
Consider the Sources Research and development Corporate profit
Economies of scale
44
One More Look at Allocation
KU X natural capital allocable KT Natural capital allocated to non-human economy GNP Natural capital allocated to human economy Time
45
Remember the Big Hope? KU GNP Time K2 K1
X natural capital remains allocable K2 X/2 conserved K1 Economic growth with technology level 2 GNP Economic growth with technology level 1 Time
46
The Apparent Reality KU GNP Time K2 K1 X/2 natural capital allocable
X/2 converted K1 GNP Economic growth with technology level 2 Economic growth with technology level 1 Time
47
Red Herring Alert! Red Herring Alert! Red Herring Alert!
48
The “Information” Economy
What is the information used for? How does one come to afford the information?
49
Fallacy Buster 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!
50
$ $ = $ $
51
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?
52
Recommendations Introductions should acknowledge spherical capacities and tradeoffs. Criteria should provide indicators of trading off. Interpretation should include observations of tradeoffs. Does technological progress occur without increased consumption?
