Fig. 1: Global variation across and within commodities in the expected extinction impact of producing 1 kg of agricultural commodity or commodity group.
From: Food impacts on species extinction risks can vary by three orders of magnitude
The lower and upper boundaries of the boxes represent the production-mass-weighted 10th and 90th percentiles, respectively. Horizontal lines represent the weighted global median (50th percentile). Where commodities are grouped, the per kilogram extinction risk values of each constituent commodity are weighted by their contribution (by mass) to the total global production of that group. Extended Data Fig. 1 provides a version of this analysis based on functional units of consumption (for example, by protein content or serving size) rather than mass.
