How To Grow A Planet

On tonight's final episode of How To Grow a Planet, Professor Iain Stewart examines one of the most underrated but perhaps one of the most important plants in the world - grass. Over eight million years ago, there was a drop in the atmosphere's carbon dioxide levels and as a result, many plants died off. But it was the moment grasses were waiting for, with less carbon dioxide in the air, grass started to really evolve.

Plants are a silent power that have shaped the Earth, creating our atmosphere and driving the evolution of every single animal in the world - including us. This fascinating three-part series offers a totally new perspective on our planet's history. Narrated and starring Professor Iain Stewart, How to Grow a Planet is a visual feast offering a stunning new perspective on Earth science.
