Low energy hobbies
From the EnergyBulletin originating from the Independent :
* Flying 1kg of asparagus from California to the UK uses 900 times more energy than the home-grown equivalent.
At this time of year, I enjoy going to my local "Pick-your-own" asparagus patch. Depending on the crop, it takes a bit of concentration and walking to isolate the stalks among the other weeds. After an hour or so of this, you can get a big enough supply to last several months (they freeze well).
The downside of the hobby: for a brief period afterwards, everything starts looking like an asparagus stalk, including roadside telephone poles.
