1 The Transition from Youth to Maturity: Toward Sustainable

Civilizations

Uncertainty, can not be effectively predicted2001,9/11, the destruction of the World Trade

Center in New York City2003, 8/14-15, electrical power outage affected

50 million people living in the northeastern US.2003, 12/26, 6.6 magnitude earthquake

destroyed the ancient city of Bam (Iran)


The need for fundamental changes

Rapid growth should be avoided the tragedy of the commonsSociety must develop new international political

and economic procedures in order to deal with a world of finite resources.

The economic capital, develop the yields of large short-term profits, often at the expense of natural capital, thus affecting the local quality of life.

The Limits to Growth


Global model Consensus

1. Technological progress is expected, and is vital, but social, economic, and political changes will also be necessary.

2. Populations and resources cannot grow forever.

3. A sharp reduction in the growth rates of population and urban-industrial development.


4. Continuing “business as usual” will not lead to a desirable future

5. Cooperative long-range approaches will be more beneficial for all parties than competitive short-term policies.

6. Decisions should be made in a holistic (systems) context.


Ecological assessment

Three paradigms1. A holistic approach is necessary when

dealing with complex systems.

2. Cooperation has greater survival value than competition when limits are approached

3. Orderly, high-quality development requires negative as well as positive feedback mechanisms.


Coming full circleHuman societies go from pioneer to matur

e status in a manner parallel to the way that natural communities undergo ecosystem development.

Continuing to act on a short-term, one-problem-one-solution basis as society grows larger and more complex leads to what economist A. E. Kahn (1966) called “ the tyranny( 苛政 ) of small decision”.


2 Ecological-Societal Gaps

1. income gap

2. food gap

3. value gap between market and nonmarket goods and services.

4. education gap

5. resource management gap


2 Ecological-Societal Gaps

Social traps, a situation in which a short-term gain is followed in the long term by a costly or deleterious situation not in the best interest of either the individual or society.

Dominion( 統治 ) versus stewardship( 管理 )

Environmental Ethics( 倫理 ) and Aesthetics( 美學 )


3 Global Sustainability

in 1987, a World commission on Environment and Development issued a report entitled Our Common Future, which has come to be known as the “Brundtland Report”, after the former Prime Minister Brundtland of Norway, who as chair of the commission.

In 1991, UNESCO issued a report entitled “Environmentally Sustainable Economic Development: building on Brundtland”.

In 1992, Earth summit in Rio de Janeiro.

Dual capitalism( 雙重資本主義 )

Dual capitalism, a business or industry would not only consider the market possibilities for a new product or service, but also plan how to produce the product or service with an efficient use of resources and with as much recycling and as little population as possible. It would also consider how to internalize source

reduction and waste management costs, so that the consumer– rather than the taxpayer – pays for waste management.

5 Long-Term Transitions

a summary of youth-maturity parallels between human and ecological systems and long-term prerequisites for achieving maturity is given in Table 11-1.

If human society can make these transitions, then we can be optimistic about the future of human kind.
