One thing that I do in my life is earn extra money just so I can afford organic food as much as possible.
But in this higher-earning job (which is not organic farming and thus not sustainable production itself), I am literally creating a bigger footprint somewhere else just to buy organic food.
Is there a metric to measure average 'environmental impact' per economic dollar, and can this then be compared to a metric for 'environmental impact' of organic vs. conventional food so that the offset of the former from the latter can be calculated?
It is fine to use an isolated example for the metric on the production side if need be, e.g. organic tomatoes vs. conventional tomatoes.
