That's anything from blackberries and chestnuts to mushrooms and wild garlic.

It's something humans have always done and recently it's become fashionable among groups of young people.

Pippa, have you ever been foraging?

We'll also be learning some useful new words and phrases, all of which you'll find on our website bbclearningenglish.com.

But before that, I have a question for you, Pippa.

As mentioned, when foraging, you must know for certain what is safe to eat.

Something definitely not safe to eat is the mushroom death cap.

As the name suggests, it's one of the world's deadliest mushrooms and it's common across the British Isles.

But what colour is it?

Are death cap mushrooms A, brown, B, white or C, red?

OK, well, we'll find out later in the programme.

First, let's meet Roshana Gray, a wild food forager living in Cape Point, South Africa.

Roshana learned how to forage from her mother-in-law, as she explains here to BBC World Service programme, The Conversation.

One skill foragers need is scanning the landscape.

Scanning means searching a wide area with your eyes to find some particular thing.

In this case, edible plants and herbs.

Our second female forager, Emily Smith, moved to rural Japan to work on a project cataloguing and collecting wild mushrooms.

With around 5,000 varieties, 300 of which are edible, mushrooms are an important part of traditional Japanese cooking.

But with names like death cap and a reputation for being poisonous, mushrooms are what many wild foragers worry about the most.

Emily discussed these worries with BBC World Service programme The Conversation.
