Global Warming and Sustainable communities

    Global warming and the resulting climate change problem is caused by excess quantities of greenhouses gases that alters the optical characteristics of the world's atmosphere.  Of all the greenhouse gases, carbon dioxide is the most significant.
    The original source of carbon dioxide was volcanic activity.  That source will continue for many millions of years.  According to scientists, the delivery of carbon dioxide by volcanic activity has been consistent for over 2 billion years.  Naturally, certain areas of the earth experienced excessive volcanic activity.  Over time, the earth's surface ecology stored CO2 at the same rate as it discharged so that an equilibrium state was achieved.  However, due to human activities, CO2 was extracted from the earth and placed back into the atmosphere so that the system became unbalanced.
    In simple terms, all matter that humans burn once was a form of plant or animal matter.  That matter was once alive and the chemistry of life is completely dependent on the element carbon, which is the basic material of all life.  The carbon atom has the unique ability to chemically link itself to itself infinitely, and to link to a range of other elements.  These links form immeasurable chains and compounds in a vast array of complexity.  The source of energy used to form these complex carbon compounds has been the energy of sunlight absorbed by plant leaves through photosynthesis.
    After the remains of living matter have been buried underground and out of contact with air for many millennia, chemical reactions stabilize the matter, which becomes fossils.  The fossil materials of greatest concern regarding the problem of global warming are coal, oil, natural gas and peat.  When these fossil forms are burned on the earth surface to make use of their energy or manufactured into degradable products, their carbon contents is converted into atmospheric carbon dioxide.  This process increases the carbon content of our biosphere.
    In short, by extracting and burning fossil carbon materials we are adding carbon to the biosphere that has been stored underground for millions of years.  
    You can review a great deal of environmental information and news at www.onebiosphere.com  You will find that the information is accurate and tough.  Environmental groups do not escape criticism.  When the environmental groups partner with Chlorox and join forces with PG&E, then the character of the environmental organization relative to environmental protection is in serious question.
