The quality of infrastructure of most islands of All Saints Bay, especially the most populous ones, under many aspects, show adequate conditions to make it arise all touristic potential of one of the biggest archipelagos in Brazil.
Part of urban sewage is still directly thrown in the sea, with no previous treatment, and it is aggravated by liquid effluents and solid residues from the occupation that happens around the bay.
Since June 05, 1999 , through a State Decree n. 7.595, the bay has been considered an AEP – Area of Environmental Protection – encompassing all the maritime extension and its islands that are located in the cities of Santo Amaro, Cachoeira, Candeias, São Francisco do Conde, Madre de Deus, Maragogipe, Simões Filho, Jaguaripe, Salinas da Margarida, Saubara, Vera Cruz, Itaparica and Salvador.
The bay that surrounds the city of Salvador and has seven islands – Frades, Bom Jesus dos Passos, Maré, Santo Antônio, Coqueiros and Língua da Baleia- is rich in biodiversity. Its islands show some mangroves, coral reefs and remaining of vegetation of Atlantic Forest. In the Southwest region, where the city of Jaguaripe is located, it can be found the island of Carapeba, whose mangroves are known as “the swamp from Bahia”. The limit between the island and the continent is a truly ecological sanctuary that is cut off by rivers and canals where it still can be found echidnas , armadillos, maned wolves and pacas, among other animals.
