Transcript of Jim Laurie - Soil Ecosystem Health: From Fungi & Nematodes to Beetles & Earthworms
Biodiversity for a Livable Climate
Loss of Biodiversity: Consequences
1. Freshwater: Reduced Availability & Quality
2. Food: Reduced Availability & Quality
3. Disease Processes in Many Species (including Humans)
4. Loss of Climate Stability - Global Warming

in New England”
6th Extinction ? - Soil ?“Big animals are like the
nutrient arteries of the
planet and if they go extinct
it is like severing these
arteries.”Chris Doughty - University of Oxford
Environment Change Institute
In the late Pleistocene, 97 genera of large
animals (megafauna) went extinct, concentrated
in the Americas and Australia.Nature Geoscience 6, 761–764 (2013)
“Poop Paucity Predicament” - David Biello, Scientific American
Carbon Lost / Acre?
Soil Extinction 1. MegaFauna Extinction in Australia and Americas
2. Barbed Wire - Herds Can’t Move to “Sweet Grass”
3. Plow - Fragment and Oxidize Soil “Dust Bowl”
4. Pesticides & Chemical Fertilizers
We are now inhibiting Photosynthesis by
tolerating bare ground. (10 to 15 billion acres)
We are inhibiting Humification
with agricultural chemicals.

“When you understand the power of self-organization, you
begin to understand why biologists worship biodiversity even
more than economists worship technology.”
“Hierarchical Systems evolve from the bottom up.
The purpose of the upper layers of the hierarchy
is to serve the purposes of the lower layers.”
from Thinking in Systems
by Donella Meadows
Places to Intervene in a System
12. Numbers - “Mostly, the numbers are not worth the sweat put into them”
(I’ll skip a few.)
4. Self-Organizing Systems (John Todd & Eco-Machines)
3. Goals (What do you want? - Allan Savory & HM)
2. Paradigms (Lynn Margulis - Microbial Symbiosis)
1. Transforming Paradigms (questioning your own beliefs and paradigms)

Lynn Margulis - Symbiosis is a key to evolution.
