Bang on. Over population is the hot potato that no one is willing to grab hold of. The human race would rather side step the real issue, arrogantly harping on about how intelligent and humane we are as a species.

Only our own habitat, though in the process, destroying the habitat of the rest of the creatures we share this planet with..
