All the while cows' methane emissions can be greatly reduced, e.g., by oxidizing methane or by using food supplements that reduce enteric fermentation. One should not forget soil erosion of typical farming, with a big environmental impact. This can be alleviated by letting cows graze on land to stock carbon in the soil (sequestration of soil organic carbon).
