Dumpster divers seek out free food as prices increase

1 September 2014 Last updated at 02:06 BST

Food is getting more expensive everywhere in the world. Even in the US, where there is low inflation, food prices have gone up by 2.5% in the last 12 months.

Driven by this and by environmental concerns, increasing numbers of people are becoming freegans - people who eat food they get for free.

In a city like New York, the greatest source of free food is often other people's garbage.

The BBC went dumpster diving with one New York freegan, Janet Kalish.

Produced by the BBC's Samira Hussain and Gianna Palmer; filmed and edited by Andrew Blum
