Donella Meadows Quotes

The world is a complex, interconnected, finite, ecological - social - psychological - economic system. We treat it as if it were not, as if it were divisible, separable, simple, and infinite. Our persistent, intractable global problems arise directly from this mismatch.

The scarcest resource is not oil, metals, clean air, capital, labour, or technology. It is our willingness to listen to each other and learn from each other and to seek the truth rather than seek to be right

We can't control systems or figure them out. But we can dance with them!

There are no separate systems. The world is a continuum. Where to draw a boundary around a system depends on the purpose of the discussion.

The first commandment of economics is: Grow. Grow forever. Companies get bigger. National economies need to swell by a certain percent each year. People should want more, make more, earn more, spend more - ever more. The first commandment of the Earth is: enough. Just so much and no more. Just so much soil. Just so much water. Just so much sunshine. Everything born of the Earth grows to its appropriate size and then stops.

The sustainability revolution will be organic. It will arise from the visions, insights, experiments and actions of billions of people. The burden of making it happen is not on the shoulders of any one person or group. No one will get the credit, but everyone can contribute.

There is too much bad news to justify complacency. There is too much good news to justify despair.

A system is a set of things people, cells, molecules, or whatever interconnected in such a way that they produce their own pattern of behavior over time... The system, to a large extent, causes its own behavior.

Since the Earth is finite, and we will have to stop expanding sometime, should we do it before or after nature's diversity is gone?

Speak the truth. Speak it loud and often, calmly but insistently, and speak it, as the Quakers say, to power. Material accumulation is not the purpose of human existence. All growth is not good. The environment is a necessity, not a luxury. There is such a thing as enough.

No one can define or measure justice, democracy, security, freedom, truth, or love. No one can define or measure any value. But if no one speaks up for them, if systems aren’t designed to produce them, if we don’t speak about them and point toward their presence or absence, they will cease to exist.

A good leader sets the right goals, gets things moving, and helps us to discover that we already know what to do.

You may be able to fool the voters, but not the atmosphere.

We don't think a sustainable society need be stagnant, boring, uniform, or rigid. It need not be, and probably could not be, centrally controlled or authoritarian. It could be a world that has the time, the resources, and the will to correct its mistakes, to innovate, to preserve the fertility of its planetary ecosystems. It could focus on mindfully increasing quality of life rather than on mindlessly expanding material consumption and the physical capital stock.

Any system, biological, economic, or social, that gets so encrusted that it cannot self-evolve, a system that systematically scorns experimentation and wipes out the raw material of innovation, is doomed over the long term on this highly variable planet.

A vision should be judged by the clarity of its values, not the clarity of its implementation path [in Mediated Modeling page 43]

Biodiversity can't be maintained by protecting a few species in a zoo, or by preserving greenbelts or national parks. To function properly, nature needs more room than that. It can maintain itself, however, without human expense, without zookeepers, park rangers, foresters or gene banks. All it needs is to be left alone.

It is not OK in this culture to talk to friends about causes you believe in, much less to ask them to join in. It's OK to blast perfect strangers with crass messages every hour of the day, but it's a tinge embarrassing, it brings up some shyness, it seems an intrusion, it risks rejection to share real heartfelt commitments. It's easier to share our cynicism with strangers than our dreams with friends.

Eleventh Commandment: Thou shalt not distort, delay, or sequester information

It is in this space of mastery over paradigms that people throw off addictions, live in constant joy, bring down empires, get locked up or burned at the stake or crucified or shot, and have impacts that last for millennia.

The actions of my government are not bearable. They devastate our natural resources and deprive our people. The politicians speak piously while practicing greed and divisiveness; they care nothing for the nation. I want to do more than withdraw my support. I want to tar and feather them.

Models can easily become so complex that they are impenetrable, unexaminable, and virtually unalterable.

Scientists worldwide agree that the reduction needed to stabilize the climate is actually more like 80 percent.

A knowledgeable and courageous U.S. president could help enormously in leading the world's nations toward saving the climate.

I call the transformed world toward which we can move ‘sustainable,’ by which I mean a great deal more than a world that merely sustains itself unchanged. I mean a world that evolves, as life on earth has evolved for three billion years, toward ever greater diversity, elegance, beauty, self-awareness, interrelationship, and spiritual realization.
