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 

Also:

* 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

@InvaderXan
sorry, but I have to call out your bullshit.

* almonds are water intensive and you shouldn't drink it, but if you're drinking cow milk instead it's even worse, in literally every way. carbon, land use, and water use.
* animal agriculture is driving deforestation in South America. 80% of soy produced in the Amazon region is used as feed for animals. if everyone started eating tofu instead of meat, we could start reforesting those areas that were destroyed by soy farming needed to raise animals for meat.
* fishing is extremely destructive to the ecosystem and fish have very high bioacumulation of heavy metals. we should stop eating them too.

* not all fake leather is plastic, and even the ones that are can last a long time. as an example, there is pineapple leather and we think more of these types of fake leather should be made instead of leather as they are more environmentally friendly than raising animals.

the rest is fine.
