Re: sahara, I watched a documentary once that showed three crocodiles still living in a little oasis in the middle of the desert, there were a few trees and enough food to sustain the population for goodness knows how many centuries.

"In the year 900, 90% of the earth's landmass was still covered with forests. By 1900 only 20% still had forests. That the forests—especially the rain forests—are the lungs of the earth has become blatantly clear to us. By clearcutting as we continue to do, we suffocate the earth—and ourselves. But an even more significant threat to the forests than mindless logging and clearcutting is soil demineralization." 90% ???...

Cont... Carbon and oxygen comprise the bulk of soil organic matter by weight, carbon almost half and oxygen a little over one third. Hydrogen and nitrogen are the next major constituents of soil organic matter, and comprise around 10% by weight in long lived forms. 98% of the nitrogen derives indirectly through fixation of atmospheric nitrogen by microbes, with around 2% being attributed to lightening causing the gas to go into aqueous...

Quote: Originally Posted by Metyu I agree: the 10,000 children that die every month from diarrhoea should concern us far more than what may or may not happen to the climate in 100 years. I agree that 10,000 children dieing of a preventable disease Is a concern. However to say we can't be concerned about two different things seems to me to be a logical fallacy. What practical steps do you recommend? And how will me not riding my bike to...

The 2007 wildfires began burning across Southern California on October 20, 2007. At least 1,500 homes were destroyed and over 500,000 acres (2,000 km², or about 770 mi²) of land burned from Santa Barbara County to the U.S.–Mexico border. One month later another fire began at Malibu, California. Comparing the Malibu fire November 2007 with the Montecito fire November 2008, one finds a correlation between the wild fires in California. The...
