Mattias Klum was born in Uppsala, Sweden in 1968 and started taking pictures in his teens. He has worked full-time as a freelance photographer since 1986, and as a cinematographer and director on numerous film and television projects since 1994. In an artistic way that is entirely his own, Klum describes and portrays animals, plants, and natural and cultural settings in the form of articles, books, films, lectures and exhibitions.

Klum’s film credits include: Borneo’s Rainforest and The Brittle Thread, a documentary about Asia’s last lions, Searching for the Giant Sea Eagle, a Wild Chronicles segment for National Geographic Channel; and The Linnaeus Expedition together with producer Folke Rydén. Klum with team have worked on the music video project Funk for Life together with renowned musician Nils Landgren. The project supports Médecins Sans Frontières (MSF) and their work in Kibera, Nairobi. Klum released two films in 2011: The Testament of Tebaran, a Penan elder’s plea to end deforestation in Borneo, and The Coral Eden, a film about biodiversity from one of the Earth’s last untouched coral reef havens. In 2014 he released a film about the Baltic Sea environment, The Contemplator, which celebrates the unparalleled beauty of this fragile sea and is a powerful reminder of what’s at stake. Klum's latest film, Vamizi - Cradle of Coral, is about a unique coral reef in the Quirimbas archipelago, just off the coast of Mozambique. We follow a team of scientists who struggle to keep it alive and safe.

In the autumn of 2013 yet another book by Klum was published called Världar av Liv. September 22 2015 Yale University Press published prof. Johan Rockström’s and Mattias’ latest book Big World Small Planet - Abundance within Planetary Boundaries.

Through compelling science and inspiring photography Big World, Small Planet achieves the mind-shift space travelers experience when looking at Earth from space: we, humanity, need to become responsible stewards of our small planet. This book is all you need for heart and brain to be convinced of the virtue of a transformation to a world that thrives within planetary boundaries.

-Richard Branson, Virgin Group
Our future hangs in the balance. We are inflicting grave damage on Planet Earth, and if we carry on with ‘business as usual’ we may reach the point of no return—when ecosystems collapse and more and more species become extinct. There is hope if only we can bridge the gap between the clever human brain and the compassionate human heart and act now. Johan Rockström and Mattias Klum lead the way with scientific clarity, powerful storytelling, and inspiring and award-winning photography.

-Dr. Jane Goodall
