Born in Spain, and now based in Mexico, photographer Jaime Rojo believes the camera is a powerful tool in conservation efforts. Combining his training in environmental sciences and understanding of visual impact, he creates elaborate projects that he hopes will draw attention to crises in the natural world, such as the decline in free-flowing rivers and the disruption of Monarch butterfly migration patterns. As part of WeTransfer’s partnership with the World Press Photo awards, Jaime gave us the story behind a chilling photo he took of thousands of endangered Monarch butterflies lying in the snow at the El Rosario Butterfly Sanctuary in Mexico.
