The New Facts of Life

by Fritjof Capra

In the coming decades, the survival of humanity will depend on our ecological literacy – our ability to understand the basic principles of ecology and to live accordingly. This means that ecoliteracy must become a critical skill for politicians, business leaders, and professionals in all spheres, and should be the most important part of education at all levels – from primary and secondary schools to colleges, universities, and the continuing education and training of professionals.

We need to teach our children, our students, and our corporate and political leaders, the fundamental facts of life – that one species' waste is another species' food; that matter cycles continually through the web of life; that the energy driving the ecological cycles flows from the sun; that diversity assures resilience; that life, from its beginning more than three billion years ago, did not take over the planet by combat but by networking.

Nature sustains life by creating and nurturing communities. No individual organism can exist in isolation. Animals depend on the photosynthesis of plants for their energy needs; plants depend on the carbon dioxide produced by animals, as well as on the nitrogen fixed by bacteria at their roots; and together plants, animals, and microorganisms regulate the entire biosphere and maintain the conditions conducive to life.

Sustainability, then, is not an individual property but a property of an entire web of relationships. It always involves a whole community. This is the profound lesson we need to learn from nature. The way to sustain life is to build and nurture community. A sustainable human community interacts with other communities – human and nonhuman – in ways that enable them to live and develop according to their nature. Sustainability does not mean that things do not change. It is a dynamic process of co-evolution rather than a static state.

Systems thinking
The fact that ecological sustainability is a property of a web of relationships means that in order to understand it properly, in order to become ecologically literate, we need to learn how to think in terms of relationships, in terms of interconnections, patterns, context. In science, this type of thinking is known as systemic thinking or "systems thinking."

Systems thinking emerged from a series of interdisciplinary dialogues among biologists, psychologists, and ecologists, in the 1920s and '30s. In all these fields, scientists realized that a living system – organism, ecosystem, or social system – is an integrated whole whose properties cannot be reduced to those of smaller parts. The "systemic" properties are properties of the whole, which none of its parts have. So, systems thinking involves a shift of perspective from the parts to the whole. The early systems thinkers coined the phrase, "The whole is more than the sum of its parts."

What exactly does this mean? In what sense is the whole more than the sum of its parts? The answer is: relationships. All the essential properties of a living system depend on the relationships among the system's components. Systems thinking means thinking in terms of relationships. Understanding life requires a shift of focus from objects to relationships.

Understanding relationships is not easy for us, because it is something that goes counter to the traditional scientific enterprise in Western culture. In science, we have been told, things need to be measured and weighed. But relationships cannot be measured and weighed; relationships need to be mapped. So there is another shift: from measuring to mapping.

Now, when you map relationships, you will find certain configurations that occur repeatedly. This is what we call a pattern. Networks, cycles, feedback loops, are examples of patterns of organization that are characteristic of life. Systems thinking involves a shift of perspective from contents to patterns.

I also want to emphasize that mapping relationships and studying patterns is not a quantitative but a qualitative approach. Systems thinking implies a shift from quantity to quality. A pattern is not a list of numbers but a visual image.

The study of relationships concerns not only the relationships among the system's components, but also those between the system as a whole and surrounding larger systems. Those relationships between the system and its environment are what we mean by context. Systems thinking is always contextual thinking. It implies a shift from objective knowledge to contextual knowledge.

Finally, we need to understand that living form is more than a shape, more than a static configuration of components in a whole. There is a continual flow of matter through a living system, while its form is maintained; there is development, and there is evolution. The understanding of living structure is inextricably linked to the understanding of metabolic and developmental processes. So, systems thinking includes a shift of emphasis from structure to process.

Systems thinking means a shift of perception from material objects and structures to the nonmaterial processes and patterns of organization that represent the very essence of life.
