These heartbreaking photo show a confused family of elephants attempting to navigate a railway line built straight through their habitat on October 16, 2012. Taken by Biplab Hazra in Bishnupur, India, the images show the extreme lengths the inhabitants of the town go to to deter elephants from damaging their crops and property. As the images show, villagers often resort to extreme tactics in an effort to drive the elephants out with one shocking photograph revealing firebombs being launched at a mother and calf as they cross the road. Elephants encroaching out of their habitats is an increasingly common occurrence with deforestation in much of India. (Photo by Biplab Hazra/Caters News Agency)
