Food from far places can be really cheap, but flying over those tomatoes all the way from Argentina produces a lot of carbon-emission. And we can grow tomatoes just as well, without the excess emission! Buying local produce simply cuts the CO2-emissions and fuel-use needed for the transportation.

I can imagine not everyone is aware of the distance your average veggies travel, and it can be hard to see what produce is local and what isn't. That's why I really like these clever package designs James Reynolds made. The boarding pass style combined with a clear notification of the so-called 'food miles' (or distance the produce has travelled), and country of origin will surely be an eye-opener to some. I wouldn't mind to be clearly informed on the globalness of my veggies by means of pretty packaging :).

In the end, I'm sure the price matters most when it comes to choosing your tomatoes, but being aware of the distance your tomatoes traveled before they ended up in your pasta could be a nice extra incentive. And if you can't figure out where those tomatoes in your supermarket come from... you could always grow your own!
