how much of a carbon footprint does your food leave?

I saw food on one of the exhibits at the Science Museum and pulled The Boy directly over to that area.
Turns out it was just fake food, but it was fake food with educational materials.
I thought it was funny how each plate was bolted to the table. This plate looked especially humorous with the tomatoes eyeballs and asparagus mouth.

And if you can see it (click on the image to get a bigger picture), this shows what the emission levels of vegetables are. Told you it was educational fake food.
