Seaweed for all

Something important has just happened in the south of the Netherlands.

Four small 'modules' have been gently lowered into the sea for the start of experiments that hope to change people’s eating habits forever (photos).

Seaweed is the future, says creator Willem Brandenburg from Plant Research International.

Guest host Chris Chambers watches the unveiling and asks whether it really is possible to bring seaweed into the mainstream.

The plight of the albatross

Midway Atoll is as far from civilisation as it's possible to get.

And that's why a million albatrosses have set up home there. But there’s still no escaping the intrusions of the modern world.

Photographer and filmmaker Chris Jordan has been documenting the impact of plastic in these birds' lives and it's not a pretty sight. (more photos)

Watch the trailer for his film Midway - Heart of the Pacific.

Bees need you

Tammy Horn loves bees.

She's traded in her job as an English professor to concentrate on giving bees in the Appalacia region of Kentucky exactly what they want all year round.

Not an easy task in an area where surface coal mining has changed the landscape and consequently the trees and plants which grow there.

Sunflowers and concrete

Richard Reynolds wants to inject more colour into people's lives.

He's one of the world's leading guerrilla gardeners and he meets host Chris behind Amsterdam's Central Station to show him how it’s possible to brighten things up.

Just a handful of seeds and a trowel are necessary.

The seed man

Ever since he was able to crawl, Ruurd Walrecht has had a love for collecting rare varieties of fruit and vegetables. Over 40 years, he built up one of the Netherlands' biggest collections.

He talks about why it's important not to lose that tradition.
