I wonder if there are any Earthlike planets without life (could they be Earthlike without life? Don't we need plants to make oxygen?). It would be comforting to know that there are escape routes in case we trash our own planet with fossil fuels, nuclear waste, cutting down too much greenery, overfishing edible sea life, not maintaining diversity of biota by concentrating on the survival only of edible life, poisoning our food with pesticides and other non-food chemicals, killing ourselves by creating superbugs via antibiotics given to livestock and poor public health meausres, etc.
