Mother Earth, also known as Gaia, deals with a lot of debris from Father Sky. What else can she do, divorce him from the ecosystem? Anyway she's shared her earthly bounty, and enabled humanity to continue living here by somehow diminishing our destructive tendencies with her good nature. Maybe it's time the human race grows up, leaves the econest, so she can get some peace and quiet? (Mission to Mars and beyond...?) Humanity is only as grounded as we feel.
