Yes, there is emerging discussion on this point as the whole locavore movement has taken off and it's become almost an assumption that it's the way to go. There are many arguments for buying local - supporting the local economy, fresher food that doesn't require as many chemicals/genetic modification to keep it presentable during long transportation, smaller carbon footprint, celebrating local culture/foodways and even the idea that some have that are bodies are not equipped to handle foods that are "exotic" to our environment. On the other side, supporting economies in third world countries and encouraging farmers/producers to thrive isn't a bad thing either. Nothing wrong with trade either - we sell to them, they sell to us, no? While many people try to buy local as much as possible, they usually don't want to give up wine, coffee, spices and citrus fruits either, not to mention out of season fruits and veggies that are flown in from Mexico, Chile or Israel. And what is local anyway? Living in eastern Canada, if the argument is about carbon footprint and freshness etc, then I'm better off buying foods produced in New England than simply "Canada," which often means it's shipping across 3 timezones from BC (ditto "buy American" - much of produce is from California, so if you live in the northeast, are you better off buying Ontario and Quebec produce, or is it more important to "buy American"?). Plus since goods and people have been moving freely across the globe for millennia, I'm not buying the idea that physically we should eat only locally (not to mention that I live in a climate where fresh food is limited during the winter months), and I think cultural exchange through food is a really good thing (that's also been going on for thousands of years). The other thing to think about is that defining what's local can be quite difficult. For example, I read a stat awhile back that said 95% or so of apple juice is made from concentrate that is produced in China. They sell the concentrate to US and Canadian food companies, who package it and can legally label it "made in US/Canada." Similarly, another source says that "Scottish salmon" need only be packaged in Scotland to be labeled that - the salmon itself can come from anywhere, so if you really want Scottish salmon, the only guarantee is to catch it yourself or buy it directly from the fisherman. It's an interesting discussion IMO with no clear black/white, and a lot of grey.
