Ser Manguezal, created by Eliseu Cavalcante, was inspired by Josué de Castro's book "Of Men and Crabs" from 1967. De Castro was a Brazilian geographer, physician, writer and activist against world hunger. In his book, Castro envisions men as crabs, learning to walk in the mangroves. This relationship between them seems to unify and blend all together making the human being part of that specific biome. This film is part of an ongoing project that examines those who depend on the mangrove ecosystem to survive, and the delicate relationship between humans and this particular ecosystem. It seeks to recognize the hard-working crab hunters of the mangroves and make their work more visible, and to bring awareness about the importance of mangroves to the environment. Worldwide, 3,400 square kilometers (1,300 square miles) of mangrove forests were lost between 2000 and 2016, or about 2% of the global mangrove area (NASA). About 62% of the losses were due to direct human causes such as agriculture and aquaculture. Mangrove degradation is greater than the average for tropical and subtropical forest loss.
