YouTube Saturday - How to Grow a Planet

The excellent BBC series, How to Build a Planet, is now available to purchase on Amazon. In this wonderfully unique series Scottish Geologist, Professor Iain Stewart, tells a stunning new story about our planet revealing how the greatest changes to the Earth have been driven, above all, by plants.

In this episode, Ian spends time in a airtight chamber full of plants. The chamber is intended to be a powerful demonstration of how plants act as the lungs of planet Earth, providing all the oxygen that sustains us. With the lights off, the levels of oxygen drop to dangerously low levels for Ian, whose rate of brain activity begins to slow. Then, with the lights on, plants reveal how important they are to animal life on the planet.

The DVD is certainly one for the collection and is available to buy on Amazon now!
