It was 28 years ago that the film director Victor Schonfeld made The Animals Film about the way humans exploit other species. He returns to the subject in a two-part documentary to give a very personal view on what, if anything, has changed since then.

In the first programme he looks at the use of animals for food and turns to experts in fields such as psychology, history, language and neurology to find out why humans seem so attracted to eating meat.

Next week, he focuses on the scientific establishment's attachment to using animals, and considers the future. Might social justice for other species actually benefit humans?
