Basic QuestionsBasic Questions
• Is there a limit for natural resources?• Can society operate without natural resources?• Is there an interrelationship between resources?• Is there an interrelationship between the rich and the poor?• What is globalization?• What is “sustainable development”?• How can we create a world with a balance in economic
activities, social stability, and environmental quality?
The Limit to Growth The Limit to Growth
Natural resources
Processingand use
Waste and pollution
Sources Society Sinks
The human population and economy depend upon constant flows of raw materialssuch as air, water, mineral, fossil fuel from earth. The human society use thoseresources to produce product for consumption. The processes constantly emit wasteand pollution back to the earth. The limit to the ability of the planetary sources to provide those stream of material and energy, and limits to the ability of the planetarySinks to absorb the pollution and waste are limits to growth for the human society.
In other words, the limits to growth are limits to the flow of materials and energyneeded to keep the society functioning.

The First ConclusionThe First Conclusion
• Human use of many essential resources and generation of many kinds of pollutants have already surpassed rates that are physically sustainable. Without significant reductions in material and energy flows, there will be in the coming decades an uncontrolled declined in per capita food output, energy use, and industrial production.
The Second ConclusionThe Second Conclusion
• This decline is not inevitable. To avoid it, two changes are necessary. The first is a comprehensive revision of policies and practices that perpetuate growth in material and energy consumption (supply-side management). The second is a rapid, drastic increase in the efficiency with which materials and energy are used (demand-side management).
The Third ConclusionThe Third Conclusion• A sustainable society is still technically and economically
possible. Based on the principle of sufficient economy, it could be much more desirable than a society that tries to solve its problem by constant expansion. The transition to a sustainable society requires a careful balance between long and short term goals, and between economics, social, and environmental viability. It emphasis on sufficiency, equity, and quality of life rather than on quantity and outputs. It require more than technology; it also requires maturity, compassion, and wisdom to manage the society.

The Underlying Concepts for The Underlying Concepts for Sustainable DevelopmentSustainable Development
• The concept of Sustainable Economy• The concept of Deep Ecology• The concept of Appropriate Technology
and Clean Production
Characteristics of a Sustainable Characteristics of a Sustainable EconomyEconomy
• Strives for constant GDP (growth in some area of the economy, shrinkage in the others)
• Stresses product durability, avoid throwaway (disposable) product
• Emphasis efficiency in resources use to ensure long-term supplies
• Minimizes waste and pollution in the total system, relying on reduce, reuse, recycling
• Minimize transportation by decentralize certain production
• Strives for equitable distribution of wealth
The Concept of Deep EcologyThe Concept of Deep Ecology
• Deep ecology– Harmony with nature– All nature has intrinsic
worth/biospecies equality– Simple material need (for
the purpose of self realization)
– Earth “supplies” limited– Doing with
enough/reuse/recycling– Social equality– Diversity
• Dominant view– Dominance over nature– Natural environment as
resources for human– Materialism– Economic growth for the
purpose of self-demand– Earth “supplies” unlimited– High technological progress as
solution for resources and waste
– Consumerism– National/centralized
community
Characteristics of Appropriate TechnologyCharacteristics of Appropriate Technology• Machines size are compatible with human• Man-machine interaction is simple• Decentralized uses of material and energy• Based on local resources• Use renewable resources whenever possible• Efficient use of energy and material• Less waste or pollution• Less capital intensive• Stress meaningful work, allowing workers to perform a variety of
tasks• Product are generally for local consumption• Product are durable, interchangeable, recyclable, reusable• The means of production are compatible with local
norms/culture/lifestyle

Nonrenewable Resources - Petroleum• Known Global Reserves: 455 x 109 bbls (US Bureau of
Mines)• Static Index: 31 years• Static Index with 5 Times Known Reserves: 155• Average Projected Annual Growth Rate (%): 3.9• Exponential Index: 20 years• Exponential Index with 5 Times Known Reserves: 50• Of course the actual nonrenewable resource availability
in the next few decades will be determined by factors much more complicated than can be expressed by either index.
The Challenge of Man’s FutureThe Challenge of Man’s Future• Within a period of time which is very short compared with
the total span of human history, supplies of fossil fuels will almost certainly be exhausted. This loss will make man completely dependent upon waterpower, atomic energy, and solar energy for driving his machines. There are no fundamental physical laws which prevent such a transition, and it is quite possible that society will be able to make the change smoothly. But it is a transition that will happen only once during the lifetime of the human species. .. if machine civilization should, because of some catastrophe, stop functioning, it will probably never again come into existence.
