The surrounding natural environment plays an important role for that. If nature is damaged, and so will the human life. For this reason, we need ways to survive as well as the thoughts that underlie the way of survival.The viewpoint of Christian ethics is one of the thoughts that can be given to add insight into human thinking, especially the Christian community on the coastel waters of Inner Ambon Bay (TAD) to realize the right lifestyle with nature.This study seeks to present the contribution of ecological theology thinking to the coastal societies in Inner Ambon Bay (TAD) so that they can renew ecological behavior in order to realize the welfare of living side by side with nature biblically. Keywords— Christian Ethics, Ecological Behavior, Inner Ambon Bay. I. INTRODUCTION Ambon City is the capital of Maluku Province which is located on Ambon Island and is classified as a small island. The city is a center of government, education, transportation, economy, defense and security, social and culture, tourism and the target of urbanization from the area around Ambon Island and outside Maluku Province.As a result, the Central Bureau of Statistics (BPS) categorizes the city as a Medium City Class which indicates a variety of changes continuously .1 On the one hand, the dynamic aims to improve the welfare of people's lives, supported by the availability of various infrastructures, human resources, natural resources and so on. On the other hand it increasingly gives an indication for the increasing problems of environmental damage, one of which is the Inner Ambon Bay waters (TAD). 1 Regency/City Profile, http://ciptakarya.pu.go.id/profil/profil/timur/maluku/ambon.pd f, Retrieved on 20 February 2012. TAD damage is caused by pollutants originating from a variety ofsociety activities, increasing population settlements that continue to grow in line with population growth, development of various infrastructures, industries and society activities in waters.Various types of pollutants are categorized as organic waste, inorganic waste, sediment and other materials. All of those enter and influence the quality of the TAD waters either directly or indirectly as has been found through plenty of findings from expert research. [1], [2], [3], [4] Diverse results of their research have given a picture of damage in different intensities with the category from “medium” to “bad”. The degradation has caused damage to the three main habitats of the waters such as coral reefs, seagrass beds and mangrove forests, thus affecting the presence of other biological resources related such as fish, [5], [6], snails, mussels, sea cucumbers, mangrove crabs, crabs, barong shrimp and tiger shrimp, sponges, seaweed and so on.[7] In the end, the problem also affected human life such as reduced income of the fishing community due to the decrease in the number of fish production from traditional fishermen groups in Waiheru, Latta, Lateri and so on.In addition to the problem of decreasing levels of fisheries production, there are also other problems such as bad influences on human health, in which 34 people got sick and some died in 1994 due to consuming shellfish in the waters of TAD. Widanyana stated that this was because people consumed shellfish contaminated with Paralytic Shellfish Poisoning from poisonous “phytoplankton” or “dinoflagelata”or “Gymnodinium bahamense”. [8]This phenomenon was repeated again in 2012 which is generally called “red tide” so that the Indonesian Institute of Sciences (LIPI) issued a warning not to consume 213 Copyright © 2019, the Authors.
