Go ahead, define sustainability. Everyone knows countless, tangled and unconvincing definitions for this word which is quickly losing steam. The problem is that we’re not sure about how sustainability relates to us except in planetary ways. We’re bombarded with many concepts that if we reduce this by 20% then we’ll get that in 30 years which helps the earth survive. All’s well, except we’re almost numb because we won’t feel the aggregate effects for quite some time. Obviously, we’re an impatient lot.
