Cyril Christo and Marie Wilkinson work together documenting relationships between indigenous people and natural world. Their primary focus has been on Africa. Christo and Wilkinson’s photography books include Lost Africa: The Eyes of Origin, exploring ecological and man-made challenges facing tribes from Ethiopia to Namibia, Walking Thunder: In the Footsteps of the African Elephant, a testament to the African elephant, and In Predatory Light: In Search of Lions, Tigers and Polar Bears, a dedication to three endangered bioregions. Their interest and concerns for the elephant have evolved over the subsequent years as the poaching situation has escalated. This long-term relationship to Africa magnifies the urgency of the struggle and presents a singular lens throughout their journey.
