Medus bites ir uzplaukušas 50 miljonus gadu laikā, katrai no 40 līdz 50 000 bišu lielajām saimēm strādājot apbrīnojamā saskaņā. Tad kādēļ pirms septiņiem gadiem bišu saimes sāka masveidā izmirt? Marla Spivaka atklāj jums 4 iemeslus, kas savstarpēji mijiedarbojas un noved pie traģiskām sekām. Tā nav vienkārši problēma, jo bites apputeksnē trešdaļu labības visā pasaulē. Vai varētu būt, ka šī apbrīnojamā suga tur rokās spoguli mums — cilvēkiem?
