TYRED OF WASTE? NIGERIA'S SOLUTION

Did you know the world throws away over a billion used car tyres yearly? It's creating a massive pile of non-biodegradable waste that's, of course, not good for our planet.

But there are ways to recycle them. We meet a Nigerian entrepreneur who's turning them into kids' playgrounds, among other things.

Amazingly, her company is the only one of its kind in Africa, and she calls on governments and multinationals to do more to help.

Getting a grip on climate change shouldn't just be down to a small firm like hers.

Hopefully, this short film will inspire others to follow in her tracks.
