This is going to sound stupid. Promise you won't laugh? Until recently I had no idea what time of year apples are harvested. It never crossed my mind. After all, they're always on the supermarket shelves, aren't they?
Isn't that weird, that my concept of food was so disconnected from nature's calendar? Supermarkets promote the idea that fruit and vegetables are available all year round. And they are: if you're willing to ship them across the globe.
Transporting food this way chucks vast amounts of Carbon Dioxide into the atmosphere. That's bad – ask Al Gore. Even worse: many of these food miles are pointless.
British apples are in season from September to January. So, what's the point in shipping New Zealand apples all the way to the UK in these months? It's an expensive luxury. Expensive for the planet, that is.
So, please please please try and eat to nature's timetable. If British food's in season, choose it over the imported stuff. (But be suspicious of British bananas or pineapples. Chances are, they were grown under rows of patio heaters.)
You'll rediscover the rhythms of the food year. It's natural to only eat apples in the autumn and winter – that's how nature works. Your food will also have less dodgy chemicals applied. How else do they keep it fresh over its 20,000 mile journey?
The poor of the world will thank you.
