蜜蜂生存咗超過五千萬年。蜂群由 40 到 50 萬隻蜜蜂組成，佢哋齊心協力。但點解蜂群喺七年前開始大量消失？Marla Spivak 揭示悲劇背後四個互相影響嘅因素。呢個唔係一般問題，因為蜜蜂為世界三分一糧作物傳播花粉。呢個偉大物種可唔可以為人類帶嚟一啲啟示？

Bees quietly sustain over a third of global crop production, yet their populations have plummeted by half since World War II. Loss of flowering plants, pesticide overload, monoculture farming, and parasites are combining to drive this collapse. Hand pollination is already needed in parts of the world where bees are gone. Restoring flower-rich landscapes can help bees recover and protect our own food supply.
