Land of rising food anxieties

by

Most Japanese cannot remember the last time they had to think deeply about where their next meal would come from. Only the eldest of Japanese with memories of food rations and scarcity from World War II and its aftermath would possess experience from which to draw. But that has changed since the triple disaster of March 11 as citizens inside and outside the catastrophe zone became increasingly concerned about both food security (e.g., food shortages at local stores) and food safety (i.e., radiation contaminated agricultural products).

The Fukushima disaster and other irreproducible experiments

by

The situation at the Fukushima nuclear reactors has evolved to one of chronic catastrophe or, more optimistically, feed and bleed followed by dialysis. While we keep getting reassured that the Fukushima crisis is not as severe as Chernobyl, I will instead look a few years further back in an effort to learn something about the present dilemma. Fukushima should be more comparable to the Three Mile Island meltdown in 1979 than Chernobyl, but it has apparently left the former eating its radioactive dust. Why? Can anything be learned from this?

The IEA reported this week that there are preliminary signs of oil demand destruction due to soaring prices. Goldman Sachs underlined this viewpoint on Tuesday by advising its clients to sell oil, copper, platinum and cotton. Prices fell in response, although concern over conflict in the Middle East and Saudi production saw prices nudging up again by the end of the week.

The planet strikes back

It’s not enough to think of Eaarth as an impotent casualty of humanity’s predations. It is also a complex organic system with many potent defenses against alien intervention — defenses it is already wielding to devastating effect when it comes to human societies. And keep this in mind: we are only at the beginning of this process.

The road to Fukushima: The nuclear industry’s wrong turn

by

Imagine a nuclear reactor that runs on fuel that could power civilization for millennia; cannot melt down; resists weapons proliferation; can be built on a relatively small parcel of land; and produces little hazardous waste. It sounds like a good idea, and it was a well-tested reality in 1970 when it was abandoned for the current crop of reactors that subject society to the kinds of catastrophes now on display in Japan.

Pour Evian on your radishes

It is also slowly dawning on the Japanese that radioactivity is not something that can be scrubbed away with soapy water. It has a Midas touch. Everything it contacts becomes fiendishly toxic. So every drop of water, concrete, foam, rubber glove, fire hose, or anything else that comes into Fukushima’s arc becomes a lethal assassin.

Radioactivity in the ocean: Diluted, but far from harmless

by

With contaminated water from Japan’s crippled Fukushima nuclear complex continuing to pour into the Pacific, scientists are concerned about how that radioactivity might affect marine life. Although the ocean’s capacity to dilute radiation is huge, signs are that nuclear isotopes are already moving up the local food chain.
