Summary

[edit]
Description
Nederlands: En wederom wordt de noodklok geluid voor onze aarde. ‘Een ecologisch armageddon’ noemt The Guardian het zelfs. De reden: in de laatste dertig jaar is 75% van alle insecten verdwenen. Dat blijkt uit Duits en Nederlands onderzoek, maar de oorzaak is een groot mysterie. Hoe groot is het gevaar voor de voedselketen, en dus voor het bestaan van de mensheid? We vragen het Hans de Kroon, hoogleraar ecologie aan de Radboud Universiteit en projectleider van het onderzoek, en Bart Knols, entomoloog, ook aan de Radboud Universiteit.
