“I would like the work we do to help build a visual legacy that can serve as a reference for future generations, so they can understand what our planet’s biodiversity is like, what it was like and, hopefully, what it continues to be.”

Roberto García-Roa (Madrid, 1984) is a biologist, researcher and photographer. For years he has travelled to different regions of the world, combining scientific research and photography to document biodiversity and bring us closer to species, ecosystems and processes that often go unnoticed.

In this audiovisual piece produced by Sonda Internacional, Roberto shares the stories behind his photographs and introduces some of the threats facing biodiversity in different parts of the world.

The journey allows us to observe beings we can barely perceive with the naked eye, learn about organisms we know very little about and better understand the ecosystems they belong to. It takes us to chimpanzee sanctuaries in Gabon, Cameroon and Guinea, travels to Antarctica and ventures into a cave in the Valencian Community, among many other places.

About the author

Roberto García-Roa holds a PhD in Biology and is a research scientist and photographer. His career combines science and photography as complementary tools for understanding nature and communicating the need to protect it. His research focuses mainly on the ecology and evolution of animal behaviour, while his photographic work documents biodiversity, how it interacts with humans and the conservation challenges facing the natural world in different regions of the planet. A member of the International League of Conservation Photographers (iLCP), his work has been recognised and exhibited nationally and internationally, and has accompanied his articles and outreach work in outlets such as National Geographic.

In-depth journalism is not economically profitable.

But it needs to exist.
