This is really one of those strange coincidences! On saturday I watched these videos and this morning I came across with@dhopeman's post about what kind of plants are better at purifying air, and their effects on humans, such as lowering blood pressure and stress levels! this threw me instantly to one of the scenes of the documentary film where Professor Stewart acts as a guinea pig and enters a tight air glass box, stuffed with all kinds of plants. The oxigen levels were driven to below 20 percent (the normal percentage of oxigen's presence on the atmosphere) When he goes in, -vital signs monitored by a team- plants save his life!

Believe it or not, the air purifier quality of plants, is one of the main reasons we humans exist! what's even more mindblowing is that we depend on plant's waste product (oxygen).

Life from Light: In this first episode Iain journeys from the spectacular caves of Vietnam to the remote deserts of Africa. He sees how plants first harnessed light from the sun and created our life-giving atmosphere. He uncovers the epic battle between the dinosaurs and the tallest trees on the planet. And, using remarkable imagery, he shows plants breathing - and for the first time talking to each other.

The Power of Flowers: In the second episode, Iain discovers how flowers have transformed our planet. He journeys to the remote islands of the South Pacific to track down the earliest flowers. In the deserts of Africa and rainforests of Vietnam, he sees how they brought brilliant colour to the most barren landscapes and sculpted the earth itself. And he learns how they drove the evolution of all animals - kick-starting our human story.

The Challenger: In the third episode, Iain discovers the remarkable impact of just one plant: grass. On the savannah of South Africa he sees how grass unleashed a firestorm to fight its greatest enemy, the forests. He shows how cutting your finger on a blade of grass shows us how it transformed life in the oceans. In Senegal, he meets the cleverest chimps in the world. And, in the ruins of the oldest temple on Earth, he tells the extraordinary story of how grass triggered human civilisation.
