In our days, we can eat food from the entire world, but we don't consider the carbon emissions that produce the transport of these ones. We can prevent an excessive pollution buying more locally food. I don't say that we can't buy foreign food at all, but a lesser number could be better. In little gestures we can do much more that we think.

I agree with you! I think that if we want to reduce our carbon emissions we have to buy fruit and vegetables in the right season and to buy products which are produced in our country, And then if we want to reduce again our emissions we must buy the products with the lesser quantity of plastic packaging, So we spare a lot of plastic!!

You're right.
Transporting food is probably one of the most polluting thing food related. Food that is often green, unripe because it needs some time to arrive on our markets' stands.
Near my house there is a "zero kilometer" shop. It is a little shop where you can buy vegtables and fruits of season, wine and other products that comes from places nearby. They are often organic too. The prices are a little bit higher than normal (not so much actually, just a little bit), for some products, but I think that it's worth it. I understand the current general economical distress, I really do, but a little sacrifice is bearable, isn't it? My family doesn't buy everything we need there, but when we do, we're happy of the quality of the products.
I'm not saying not to eat exotic fruits, I'm just saying to avoid them sometimes, if possible.

I thing the "zero kilometer" shop is a very beautiful thing! Unfortunately where I live  there aren't shops like this, But when my mother goes to shop in a supermarket, she try to buy products which are produced in our country, and when it's possible organic too. I now that the prices are more higher than the normal products, but I agree with you that a litte sacrifice is possible to reduce the carbon emissions. I hope that in the next years more "zero kilometer" shops will be open in my city.

Also here those shops are quite recent and not so popular. I mean, there are some of them in all my country and I consider it to be a good achievement. The only thing that I feel sorry for is that they're not popular. If it wasn't near my house, probably I'd have hardly heard of it. It has opened a year ago and I hope that soon others will follow it. I believe that more of those shops would help local economy (by buying things from small local producers), save some of those little producers such as farmers, winemakers, bakers, and so on from failure, and promoting local articles.
As I already said, I hope that more of those shops will open soon, they're quite interesting.
