You're about to listen to a BBC podcast and maybe it's when I had a hand in.

I'm Tammy Walker and I produce podcasts for the BBC.

My role is to give new and diverse creators a voice with the opportunity to build a career.

That's the thing I love about podcasts.

You start with just a good idea, but then you have the space to see where it goes.

And doing that at the BBC means we can really run with the best stories

while developing the most unique audio talent.

So if you like what you hear, why not check out the huge range of podcast we've got on BBC

Sounds. Right, it is Saturday morning. We are out in freezing cold West London next to a

motorway on a kind of patch of scrub land because my

producer Maraker told me to and character building we're going to plant some

trees We're going to plant some trees.

You're listening to the Crowd Science Podcast from the BBC World Service. I'm Marnie Chasterton.

And that was a community event to plant 10,000 saplings in one day organized by trees for cities.

All right, let's get you a spade.

Come on morning, put your back into it.

Do you want to go?

Well, I'm okay, thanks.

Look, wherever you put this, it's hitting rock.

Maybe we should dig in a different spot.

Oh, this is better.

Okay, start again.
