A Quote by Fritjof Capra on ecological cycles, carbon dioxide, organic compounds, plants, green, photosynthesis, and respiration

Dissipative Structures - Chapter 8 – excerpt from page 178Green plants play a vital role in the flow of energy through all ecological cycles. Their roots take in water and mineral salts from the earth, and the resulting juices rise up to the to the leaves, where they combine with carbon dioxide (CO2) from the air to form sugars and other organic compounds. (These include cellulose, the main structural element of cell walls.) In this marvelous process, known as photosynthesis, solar energy is converted into chemical energy and bound in the organic substances, while oxygen is released into the air to be taken up again by other plants, and by animals, in the process of respiration.

By blending water and minerals from below with sunlight and CO2 from above, green plants link the earth to the sky. We tend to believe that plants grow out of the soil, but in fact most of their substance comes from the air. The bulk of the cellulose and the other organic compounds produced through photosynthesis consists of heavy carbon and oxygen atoms, which plants take directly from the air in the form of CO2. Thus the weight of a wooden log comes almost entirely from the air. When we burn a log in a fireplace, oxygen and carbon combine once more into CO2, and in the light and heat of the fire we recover part of the solar energy that went into making the wood.

Epilogue – Ecological Literacy – excerpt from page 297

Reconnecting with the web of life means building and nurturing sustainable communities in which we can satisfy our needs and aspirations without diminishing the chances of further generations. For this task we can learn valuable lessons from the study of ecosystems, which are sustainable communities of plants, animals and microorganisms. To understand these lessons, we need to learn the basic principles of ecology. We need to become, as it were, ecologically literate. Being ecologically literate, or “ecoliterate,” means understanding the principles of organization of ecological communities (ecosystems) and using those principles creating sustainable human communities. We need to revitalize our communities – including our educational communities, business communities, and political communities – so that the principles of ecology become manifest in them as principles of education, management, and politics.

A Quote by Fritjof Capra on harmonious interrelatedness, dynamic balance, and survival of our whole civilisation

I believe that the world view implied by modern physics is inconsistent with our present society, which does NOT reflect the HARMONIOUS INTERRELATEDNESS we observe in nature. To achieve such a state of DYNAMIC BALANCE, a radically different SOCIAL and ECONOMIC STRUCTURE will be needed: a cultural revolution in the true sense of the word. The survival of our whole civilisation may depend on whether we can bring about such change. IT WILL DEPEND, ultimately, on our ability to adopt some of the YIN attitudes of EASTERN mysticism; to experience the wholeness of nature and the ART of  LIVING with it in HARMONY

A Quote by Fritjof Capra on life, nature, sustainability, and earth

We do not need to invent sustainable human communities. We can learn from societies that have lived sustainably for centuries. We can also model communities after nature's ecosystems, which are sustainable communities of plants, animals, and microorganisms. Since the outstanding characteristic of the biosphere is its inherent ability to sustain life, a sustainable human community must be designed in such a manner that its technologies and social institutions honor, support, and cooperate with nature's inherent ability to sustain life.
