All That Breathes begins with a stunning three-minute slow pan across a derelict, empty lot. We see mounds of garbage. And slowly, living beings emerge. Rats scurry across the frame as traffic passes in the background. Through the documentary, director Shaunak Sen returns to this idea of the precarious balance between nature and human beings and the impossible ways in which overpopulation and pollution force both to adapt. Later we see mosquitoes, dogs, cows, monkeys, pigs, horses, lizards, a frog, a caterpillar and even a turtle somehow surviving the urban jungle. Meanwhile, the birds, who glide over the bustling, bursting capital city, as though they are swimming, keep falling down. And Nadeem and Mohammad keep trying to save them. Early in the film, one of them explains: It is said that feeding kites earns sawab, which means religious credit or reward, because when they eat the meat you offer, they eat away your difficulties.
