After two years of research and photography I realized that the discourse on food production can be infinitely refined and that this often puts supposed advantages and disadvantages in a new light. Scaling-up can actually enhance animal welfare, for example, and organic production is not always better for the environment. Often, an excessively one-sided approach to the subject of food is a barrier to real solutions. Food is simply too wide-ranging and complex a subject for one-liners or to be describing in terms of black and white. More info in Food, background.
