offset land

And some of this extra land is offset by soil erosion.

部分额外土地被土壤侵蚀消耗着。

But that effect was offset by warming-associated drought that limited growth in the Southern Hemisphere, resulting in a net global loss of land productivity.

但是，这种积极影响被气候变暖带来的干旱所抵消，限制了南半球的植物生长，导致全球土地生产力出现负增长。

Even if organic farming does consume a little less energy and produce a little less pollution, that must be offset against lower yields and greater land use.

即便有机种植的确消耗更少能源，产生更少污染，但也会被低产以及使用更多耕地所抵消。
