That's an interesting point - oil prices doubling and affecting the cost of imported/transported 'out of season' produce (is that code for African or more likely, non-EU?).

If locally-grown produce is available and fairly priced, it is up to consumers to buy it up and demand more, if they want local farmers to produce more food crops and less biodiesel.

Here's a challenge: compare product & prices at your local fruit shop / growers market vs. your oligopolist grocery chain.
- Is there a noticeable price difference due to local v imported/distance-transported/out-of-season 'stored' produce?
