Kroodsma (Reports, 23 February 2018, p. 904) mapped the global footprint of fisheries. Their estimates of footprint and resulting contrasts between the scale of fishing and agriculture are an artifact of the spatial scale of analysis. Reanalyses of their global (all vessels) and regional (trawling) data at higher resolution reduced footprint estimates by factors of >10 and >5, respectively.
克罗兹马（Kroodsma）（报道，2018 年 2 月 23 日，第 904 页）绘制了渔业的全球足迹图。他们对足迹的估计以及由此产生的渔业与农业规模之间的对比，是分析空间尺度的一种产物。对他们的全球（所有船只）和区域（拖网）数据进行更高分辨率的重新分析，分别将足迹估计值降低了 10 倍以上和 5 倍以上。
