Well travelled?

Knowlage is knowing that a tomato is a fruit
Wisdom is knowing not to put it in a fruit salad

After being told this summer by ITN to buy local food to save the environment there was a bloke on the radio today saying that it's more environmental friendly to buy spanish or african tomatos rather than ones from the UK (even in the summer) as they are more likely to have been grown outside rather than in a hot house hence less carbon emitted to grow the toms. Ever get the feeling environmentalists are making some of this stuff up for their own entertainment?

"sun dried tomatos" mmm, lovely how wonderful,
"tomatos dried in the airing cupboard" yuck how horrible

their both dried out tomato's what's the differences
