It isn't always better for the environment to buy food locally. How it was farmed and how it was imported matter too. Most of the carbon footprint of groceries is from how they were grown and not how they were transported.
If it's in season where you live, then locally grown is best. If it's out of season, you need to consider a more nuanced point of view.
some surprising sustainability
* Growing almonds for almond milk damages ecosystems and uses a *lot* of water. 80% of the world's almonds come from California, where severe droughts can be a problem
* Soy farming drives deforestation in South America. Tofu can have twice the carbon footprint of chicken
* Fish populations are dynamic. Sustainable fishing leaves land open for reforestation
* Bioplastics are not necessarily better than recyclable plastics like PET
* Industrial cooking is more efficient than home cooking. Tinned tomatoes, chick peas, etc can be a good option
* Cling film is plastic, and plastic is not good. But if you use it carefully, you can prevent food waste, which is worse. Beeswax wrapping is ideal
* Leather can last over a decade, and is biodegradable. Fake leather is made from short lived plastic
* Cotton production is energy intensive. A cotton bag needs to be used 149 times to be more carbon efficient than plastic. Get a good one. Use it often
Lots of people reply-guying it up about soy. Yes, a lot of soy is used as animal feed. That doesn't change the fact that, as things stand, tofu can have a higher carbon footprint than some meat does. And buying it from the wrong suppliers can support the same people destroying the rainforest and farming cattle.
Come on people, think a little before you take umbrage.
@InvaderXan I'm of the thought that if you have to destroy the local environment to grow/farm X then that is the complete opposite of being sustainable. Likewise if you have to import a subsitute rather than use/eat what is produced next door to you.
The point is that food production out of season, while not any more damaging to the local environment, produces more emissions than importing.
Heating large greenhouses during winter typically uses a lot more energy than just shipping vegetables from someplace where they've been growing outdoors.
It may be produced next door. That doesn't mean it's sustainable.
@Rae Ahhh, I see! Yes, that's certainly a good way to do things.
Honestly, I prefer it when things are seasonal. It's makes some things feel more special when you can only get them during certain times of year, I think. A lot of foods in Japan are like this too, because very little is imported there.
@InvaderXan It took a while to make a conscious effort to be like this here.
We can grow strawberries at a commercial level in Waterford for a few months of the year and omg fresh strawberries are crazy good! The smell! The flavour! You get them from Spain (like normally) and they're way too flat because they've been in storage for a while.
@Rae Strawberries also like the rain. It's one of the reasons the UK and Ireland grow them so well!
