“We do have a pretty miserable track record of trying to fix large scale ecosystems. We’ve introduced species that have gone on to do terrible things; we’ve removed species that have had disastrous effects. So I think we need to learn from those large-scale lessons, and I think we can only do that if we truly understand that. What we’re talking about is ecosystem engineering: We’re shaping very, very vast worlds, even if those worlds are microscopic and contained within us.”
