We're a planet addicted to chicken - and our appetites fuel a massive global industry... but is it one we should support?

As Chris wrestles with how he personally feels about this weird and wonderful bird, he decides to take a look at the business as a whole: a global industry that's cited by some as a shining example of a super-efficient food production system, one that could help drive food security around the world.

But others say it’s a cruel, destructive and outdated structure that makes a few people richer while exploiting others – along with animals and the environment.

In Brazil, one of the world’s biggest chicken and soya producers, our reporter Leonardo Milano hears accusations of threats and pollution relating to the feed sector; while in Africa, Chris learns about poultry-farming initiatives helping to make struggling nations more food-secure.

And then there are the other challenges that the industry is wrestling with: from antimicrobial resistance to the threat of another major global pandemic, potentially stemming from chicken farms…

So is there a ‘big business bad guy’ to blame – or does responsibility lie closer to home, with unquestioning consumers like Chris?
