Hunting animals used to be central to the survival of most human communities over most of human history, whether it be for food or medicines or to use their fur and skin as clothes and rugs.

While we try to inculcate the values of sustainability in people today through classes and lectures, such values used to be a matter of common sense. If you kill all the animals this year, what are you going to hunt next year?...
