Empty skies, empty shelves

Chances are you're enjoying a fine and unusually quiet morning today. The reason for this is the closure of our airspace to civilian air traffic, leaving the sky empty for the first time since KLM commenced operations in 1920. Thanks to an Icelandic volcano, we have our first glimpse of a world without air travel.

Under the flightpath at Heathrow, householders are finding out what it's like to be able to leave windows open; in Manchester, one anxious lady complained to local radio that she's had to leave her radio on loud because the quiet is scaring her; and in many supermarkets the shelves are already emptying of perishable items as supplies of airfreighted food dry up. Since 95% of us shop at supermarkets*, it's the last one that should really scare you. If you're one of the people who scoffed at Lord Cameron's 'nine meals from anarchy' observation in 2007, it may be time to think again.

Predictions about how long the ash cloud will last vary, and media coverage still seems to be concentrating on the poor souls whose holidays are being disrupted, but it's worthwhile reflecting that the last eruption at Eyjafjallajokull lasted for two years (1821-1823). What would it mean for Europe if chunks of airspace had to be closed every time the wind blew from the north for a few days?

To paraphrase Ralph Waldo Emerson, going green is a journey, not a destination. If your own journey has not yet included growing some of your own food, or at least starting to eat locally and seasonally, then this might be a good time to consider it.
