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?

In just over a week's time, we'll be announcing the winners of this year's BBC Food and Farming Awards,

ten different winners in ten very different categories.

In this programme, which is something of a build-up to the main event,

we're taking a close look at the stories our judges uncovered in the future food category. One, we set up to recognise

big, ambitious projects and the innovators behind them. Projects that could influence the

way our food will be grown, sold and distributed for years to come. The first of our three

future food ideas couldn't have been found in a more beautiful

setting. Just off of Northern Ireland's most northern coast, you'll find the island of Rathlin,

More specifically, kelp, a crop hidden underwater, but marked out by a row of floating orange spheres.

From one of the boys, you've just pulled up a rope with a hook.
