Sun bears are victims of bile farming in Asia where bears are kept in crush cages for years, with sanctuaries providing rehabilitation for rescued bears with complex physical and psychological needs.
Bear bile farming represents one of the most severe documented examples of captive animal welfare abuse. Bears confined in crush cages may spend their entire adult lives unable to turn around or stand upright, with chronic wounds from bile extraction devices. The psychological damage from years of such confinement causes severe stereotypic behaviors and profound fear responses. Rehabilitation of rescued bears requires years of patient care by specialist facilities. The welfare case against bile farming is absolute and the existence of herbal and synthetic alternatives eliminates any justification based on medicinal necessity. Consumer and policy pressure on producing countries remains essential.
