A Fly Future?

We're in South Africa again to find out whether fly larvae could help humans eat more meat and fish.

As the global population expands, traditional feed sources such as fishmeal, soya and grains, could put increasing pressure on the environment, depleting oceans and reducing biodiversity. Alternative protein sources based on insects are being developed by a number of companies across the world. In this episode we explore whether they are as effective as traditional feeds, and how big the industry is likely to get.

Plus, might maggots be able to ease the world’s landfill problems too?
