Photographer Jimmy Nelson dedicates 408 pages to the world’s endangered tribes. These are the people who live closest to our roots as hunter gatherers and remain in tune with their own environment. As technology and civilization sweeps land and people within its beastly body, these pockets of peaceful societies are becoming fewer and fewer. Nelson’s lens immortalizes the unique and striking cultures along with their art and traditions. “Before They Pass Away” captures a cultural diversity that soon may no longer exist. This hardcover books presents a rare look into a different Earth, complete with breathtaking landscapes.
