Colony collapse disorder and other honey bee population threats affect billions of individual bees and create welfare concerns beyond the familiar conservation framing.
The welfare of individual bees within colonies is rarely considered but potentially significant given evidence of bee sentience. Varroa mite infestation causes chronic immune suppression and weakening in affected bees. Pesticide-impaired bees that cannot navigate home face isolation and death. Bees in monoculture conditions face nutritional deficiency over extended periods. Colony collapse, which may involve disoriented bees unable to return home, may represent a welfare crisis for millions of individuals. The scale of bee population losses - billions of individuals annually - means that even small probabilities of sentience translate to enormous potential welfare impacts.
