Celebrating nature, science, space and the human race, BBC Earth brings you face-to-face with it all. For a brand new series called #Trees, I collaborated with BBC Earth to uncover the lonely urban-dwelling tree: the street tree. In the mini-doc, I explain the history of Amsterdam's street trees, the problem with monocultures, why soil quality matters, and how we can use emerging technologies to foster street tree diversity using the Internet of Nature. Find out more about the amazing shrubbery we share our cities with in this fun short.
