Wasting food has become a way of life for many Londoners who, according to one Western-led study, are tossing an average of $600 into the trash every year.

Van der Werf served as lead author of the paper "Food for naught: Using the theory of planned behaviour to better understand household food wasting behaviour," newly published in Canadian Geographer.

Fruit and vegetables were tossed most often, and usually because respondents said they had bought more than they needed and it had spoiled.
