The Bird of Dawn

Finally I am in Saudi Arabia.  So many new impressions and new thoughts. I customarily watch here Al Jazeera International and the French News 24 Channel, and I never watch American TV.  I am simply tired of American navel gazing and the low quality of U.S.-based programming available here. Today, on Al Jazeera I saw a program about a group of Iranian and French women and men, who wanted to have a public concert in Iran.  After a long struggle, the authorities relented and the group sang.  And what a concert it was! This was the introduction by an Iranian female singer: We are the free men, who are not scared We are secrets that never die We are voices of who resist We are free and our world is free. At the end, another Iranian woman sang in the most beautiful voice: Of the just and the unjust They only spoke and did nothing Oh, God! Oh, God! See the chasm between their words and their actions. In-between they sang the "Bird of Dawn," a metaphor for h...

The last chapter: Industrial agriculture

As I have argued in the previous three blogs, industrial agriculture is the largest human project that impacts the Earth more broadly than any other human activity.  One needs to keep in mind that compared with the global environmental impacts of industrial agriculture, a Macondo well-like blowout is a child's play.  I know it, because I co-wrote a book on this subject with the famous historian and archeologist, Joe Tainter.  For example, in the Amazon forest the underbrush fires set by humans affect 3 million square kilometers, an area of India.  See NASA for a summary of this global catastrophe . Researchers for the first time mapped the extent and frequency of understory fires across a study area (green) spanning 1.2 million square miles (3 million square kilometers) in the southern Amazon forest. Fires were widespread across the forest frontier during the study period from 1999-2010. Recurrent fires, however, are concentrated in areas favored by the con...

Ethanol in fuel - Up close and personal

Five years ago, I published a short letter to Science about the real biofuel cycles.  The letter was published after a long struggle with the journal's Editor of Physical Sciences, Dr. R. Brooks Hanson, who limited my letter to 150 words, and tried to prevent me from putting in a link to these supporting materials . The whole fight was for not, because the link has been broken since I left Berkeley.  In these supporting materials, I made the following two statements: Furfural in an impure ethanol mixture will gradually dissolve almost any rubber or elastomeric seals or ducts in storage systems and car fuel systems. (Page 13) Finally, ethanol dissolves a large number of substances insoluble in water and acids, such as many inorganic salts, phosphorus, sulfur, iodine, resins, essential oils, fats, coloring matters, etc. (Wright, 1994).  Therefore, the metal-rich sludge in fuel tanks of most older cars will dissolve in ethanol-containing gasoline and accelerate corrosio...
