My high school friends have begun to suspect I haven't told them the full story of my life.

"Why did you leave Sierra Leone?"

"Because of the war."

"Did you witness some fighting?"

Everyone in the country did.

"You mean you saw people running around with guns and shooting each other?"

"Yes, all the time."

"COOL."

I smile a little.

"You should tell us about it sometime."

"Yes, sometime."

A Long Way Gone is an autobiographical book written by Ishmael Beah who spent several years caught in the middle of the civil war in Sierra Leone. It spans pretty much exactly the period of his exposure to the war, starting with the day before the fighting first impacted his life in 1993 and ending with his eventual escape from Sierra Leone into neighboring Guinea in 1997. Only glimpses of his life both before and after this appear as flashbacks or flash forwards in the story.

As Zimbabwe rapidly slips into chaos, we do well to remember what is sadly common in modern African history: well-armed and ill disciplined gangs, often mostly children who should be in Middle School or High School, led by violent strongmen locked in brutal and prolonged wars over who gets to loot a given country. Sometimes there are religious overtones. Sometimes racial/ethnic/tribal overtones. Often economic conflicts are also involved. But generally no one benefits from these conflicts except a handful of top men who squirrel away as much wealth as they can for their own benefit.

I have always been a fan of Japan. I have been there four times, including on my honeymoon. I even had the pleasure of living for a year in Kyoto working at Kyoto University. It is, in many ways, a wonderful place and I do hope to go back when time and money permit. I even am teaching my son what little Japanese language I still remember.

But there are always strange undercurrents in Japan. Korean and Chinese friends of mine cannot understand why I ever would visit Japan. They have an anger towards Japan that Americans have a hard time understanding. The presence of the yakuza (Japanese mafia) in Japan is omnipresent, once you are aware of it, which seems strange for an otherwise so law abiding nation. When World War II comes up in conversation, many Japanese still think Japan was justified in its imperialism and that America should apologize for the nuclear bombings and for the occupation. It is a constant source of scandal that Japanese leaders frequently downplay and misrepresent Japanese imperialism in Asia. I was amazed at how unresolved WW II seems in Japan and in Asia.

Biodiesel is one of the most intriguing of those new possibilities...crops of soybeans and rapeseed and maybe even algae, grown by present day farmers, processed into a diesel fuel substitute that works just fine in modern Volkswagons and Mack trucks and school buses--even in the oil-burning furnace down in the basement. It is potentially a truely sweet solution, offering a new market for hard-pressed local farmers even as it begins to help solve some of our most pressing environmental problems. Greg Pahl's book...manages to raise the right questions (and raise them early enough) so that we can perhaps build a structure for this developing industry that serves local farmers and processors instead of simply corporate agribusiness giants.

--Bill McKibben in the Forward to Greg Pahl's Biodiesel

Biodiesel has been getting a bad name because of the potential for competition with food production. It has always struck me that some of the loudest voices criticizing biodiesel has come from the oil, coal and nuke lobbies. But it did seem like competition with food production may be a critical problem with biodiesel.
