In this never before published photo, Christina Mittermeier captures the serious issue of water scarcity in a unique way. Colorful laundry contrasts the stark browns of a desiccated Madagascar riverbed as two emaciated cows continue their search for water. The image is a reminder of the daily competition for life-sustaining resources in many parts of the world. (Photo by Cristina Mittermeier/National Geographic Creative)
