Prof. dr. Marcel Dicke is an ecologist with a special interest in the relation between plants and insects. He is a recipient of the NWO-Spinoza award, also known as the Dutch Nobel prize. The central theme in his research is the way that plants define the lives of insects. In his TEDxAmsterdam talk, he explains why we should all eat insects! His surprising talk was followed by the serving of some delicious snacks.
