organizing and categorizing the limits[edit]

These limits can be organized or categorized by: Material, Energy, and Waste disposal, and by renewable or non-renewable resources, and source or sink.--Lbeaumont 12:34, 15 February 2011 (UTC)

Organizing by Footprint Categories[edit]

Consider organizing the resources according to these catagories:

They are (i) growing crops for food, animal feed, fiber, oil, and rubber; (ii) grazing animals for meat, hides, wool, and milk; (iii) harvesting timber for wood, fiber, and fuel; (iv) marine and freshwater fishing; (v) accommodating infrastructure for housing, transportation, industrial production, and hydro-electric power; and (vi) burning fossil fuel.

These are used in the paper at: www.pnas.org/cgi/doi/10.1073/pnas.142033699

System Dynamic Model of Fertile Soil[edit]

I am looking for a system dynamic model of fertile soil. This would describe decay of organic matter, etc. over a long period of time (e.g. centuries) as the primary generative flow and describe agriculture activities (growing and harvesting crops, water flows, fertilizer use, etc) as the primary depletion flows. The quantity and quality (e.g. fertility) of the soil would both be modeled. If you know of such a model, please let me know. Thanks! --Lbeaumont 14:54, 10 March 2011 (UTC)

Simcity meets limits to growth[edit]

it would be way cool to have a game along the lines of simcity based on the world3 limits to growth model. Students could play the game (create simulation runs) based on their own decisions for allocating resources and consuming resources. It could bring the concepts alive and increase awareness and ownership for analogous decisions in the real world. --Lbeaumont 13:18, 12 March 2011 (UTC)

Limits to economic growth[edit]

I have felt that economic growth is capital construction resulting economic shrinking. A recent attempt to work w/ the wikimedia foundation showed me that wiki growth also answers to the limited growth equation. As an example of economics, the DOW index has been shrinking for 30-40 years if you account for inflation--which they don't. Growth prior to the shrinking was the result of shifting power after WWII, I think.

Point being, if you are not growing, no reason to attempt to be as if you are. So what is growth? Illusion. But environmental deprecation is real: real vs. illusion. The illusionists will tell you that they are your reality,and call the police if you need to be reminded: smoke, mirrors and court appearances.--JohnBessa66.pngBessatalk 21:52, 16 May 2011 (UTC)

I suggest reading the book "Prosperity Without Growth" by Tim Jackson --Lbeaumont 12:27, 4 June 2011 (UTC)

To-do list[edit]

lots of work remains to be done throughout the course, including these significant efforts:

  • create waste / sink input-output flow diagrams. For each major waste type identify the major sources and their flow rates worldwide and per unit. Identify the major sinks and the flow rates and assimilation rates.
  • establish quantitative limits for each resource. Include food for all, CO2 limits, etc. Use the limits TED talk and other sources.
  • establish a "standard human" in terms of their consumption of food, water, energy, materials, and waste products.
  • describe "my corner of the earth" by dividing land area and other resources by the total population to illustrate how much land we each have and how it is allocated to forest, crops, living space, water, etc per person.
  • draw the macro-level interrelationship diagram for the overall system.
  • develop the concept of prosperity without growth
  • integrate Khan Academy style videos into each lesson.
  • Create PowerPoint-style slides for each lesson.
