The Earth could get along just fine without us. If anyone can think of an ecosystem function that requires our presence, I would like to hear about it. Circumstantial and fossil evidence indicates that even when human numbers were small, the fires, animal drives, and plant preferences had harmful effects. Ecosystem resilience absorbed early human impacts, but now with more than seven billion of us, the impacts are simply overwhelming earth ecosystems. Livestock? Earth could tolerate a few domestic beasts, but not the billions we have now.
