I'm Rory Stewart and I grew up wanting to be a hero and I'm still fascinated by the ideas of heroism.

In my new series, I'm taking in the long sweep of history from Achilles to Zelensky and asking, what is a hero?

Simply doing your job, being a decent human being.

A true hero is someone who just kind of shines by

their own light and that light is to be recognised by others. The long history of heroism with me,

Rory Stewart. Listen on BBC Sounds. This Scotland Outdoors podcast from BBC Radio Scotland.

Hello and thanks for choosing to listen to this. I'm Mark Stephen. You've probably heard the phrase, act locally, think globally. I've always liked it without being

terribly certain what it meant until a couple of weeks ago when I saw it in action.

Josh Donaldson has got a sizable social media presence as Earth Drop,

something like quarter of a million followers on Instagram,

one and a half million on TikTok.

And what are all these people watching him do?

Well, basically, pick up litter in his

area. So that's the act locally bit. But Josh has got some very interesting ideas on what to do

with that litter and some serious ambitions as to how far his message or example might spread.

And that's the bit that I think is potentially global. I met Josh in a wood

behind an industrial estate in the outskirts of our broof, a town on the east coast of Scotland.

I spend my time out in the woods picking up litter, rubbish, the stuff that other folk discard,

I suppose it's the best way to put it.

Ordinarily it's things like bottles of water and juice and cans and crisp packets,

the kind of things that folk take on a walk with them and then leave behind them.

The worst end of the scale is definitely the fly tipping, at which point it becomes kind of a potluck.
