michael, this is a *really* complicated issue. Definitely buying
local puts money in your community's pockets, and I'd like to see more of that! Evaluating what "local" means and how to accomplish it gets trickier.
Example 1: You buy locally made jam from an organic farmer: Did he actually buy the fruit? the sugar? the spice? What about the jar? Many health departments require a new jar every time for sales which I don't get since they used to wash and
reuse pop bottles and still do beer bottles! Are the bottles sustainably produced and did they arrive via sustainable transportation. In other words, compromise is likely necessary. Perfection can be the enemy of "improvement"!
Example 2: Does organic equal sustainable? Organic started out much more sustainable than most modern farming practices, but when big business got involved, they "defined" organic in ways that allow the farmer to potentially use materials and methods that may not be sustainable. I can remember reading a chart about the huge quantity of minerals that left 10 acres of "market garden" in the form of veggies. It *really* amazed me how much calcium would leave in the form of lettuce and kale! It used to be in closed loop systems that much of those chemicals would recycle through the system, going back into the soil, but buying lettuce from California - even if organic - doesn't return the results to the farm which exported it.
Example 3: Where does the
water come from? Farming and Industrial practices often use huge amounts of water. That's been raised as a major sustainability issue. There are wetlands and deltas that are drying up because too much water is being removed from a river before it reaches the ocean. Hydro power is sold as "green energy" but often behind a dam there are silt build-up issues and below the dam, silt that used to provide fertility and support deltas is not there to do so.
We have a society that seems to be built on the concept that "bigger is better" and personally I believe that in many cases, "simpler, smaller, sustainable"
should be the new watchwords.
