“Locusts & Men”. Oppression, interaction, collaboration. In the life cycle of nature nothing is lost, but the coexistence of different species is sometimes difficult. In Madagascar periodically returns the archaic antagonism between man and the migratory locust, in a circle of life where the two species are looking for space and food for their survival. At the end of the day a man walks home carrying on his shoulders the heavy bag which contains the locusts captured during the day. The insects provide nutritious meals for the man and his family.
