Mangroves cover 13,989 sq km of Brazil’s coast and are an important protection against climate change, with one acre of mangrove forest absorbing nearly the same amount of carbon dioxide as an acre of Amazon rainforest. The forests also protect the coast from eroding as intense storms grow more frequent.
Fisherman Jose da Cruz, above, makes his living by fishing for crabs where freshwater rivers meet the brackish Atlantic Ocean.
Instead of a rod or a net, he uses his hands to search for crabs in the mud among the mangrove trees, sometimes lying flat on the ground and reaching deep down. His daily catch of several dozen crabs will earn him 200 reais (£40) a week, enough on which to survive.
