Some of the problems affecting the whole society has to do with subject of human behavior, what belongs to the field of ethics; therefore, involves the mastery of relations with oneself and others humans. This is only part of the problem ethical. The activities human have changed the environment so dramatically over the last fifty years are point of endangering the existence of life on earth, and this has also become a matter of ethical concern. Environmental problems are not due of fates that are linked intrinsically with human interventions expressed in many different ways in economy, science and technology, politics and law and society at whole. From this point of view, we need to wonder about the nature of the interventions or human actions. There are inevitable questions in an environmental analysis, and ethics incorporated as a way of asking about the conduct of men toward whole biosphere. Traditionally, the subject of ethics has not been linked to matters pertaining to the nature and the environment. The old questions of the relationship between being and duty, cause and purpose, the nature and value, are the domain of ethics that have been confined to an area which has left excluded the subject of environment (Desjardins 2001).
Discussion
An ethic centred on humanSome believe that environmental policies should be evaluated solely on the basis of its impact on people. This is an environmental ethic centred on human beings. Although the classical utilitarian's include the suffering of animals in their ethical calculations, a variant of utilitarianism, which urges us to maximize the surplus of human happiness on human unhappiness, is an example of people-centred ethics. Taking ethics seriously like us to calculate the effects of options on the human happiness and unhappiness. We could see that mining would reduce the ecological richness of the marshes, and if it did this cause the unhappiness of some people, for example, some may be moved by the situation of certain animals, others might be saddened by the loss of species. Such Members of future generations, could miss out on recreational or aesthetic enjoyment individuals, others may be adversely affected by the resulting climate changes, changing tides and so on. And others may be psychologically affected by the theft of areas which have a spiritual connection. It would have to subtract these negative effects of any increases in happiness resulting from the mine. Ethics centered men could allow considerable agreement with environmentalists on how to proceed. This would depend on the facts about the effects that changes in the environment have on people (Gaumnitz 2004). Animal-centered ethicsThere is a conception of ethics that considers not only morally relevant to people but also to nonhuman animals, includes in its scope to all animals. Many of the things we do to the natural environment adversely affect nonhuman animals, and this is relevant to this ethic. For example, if we think the cyanide pollution of the South Alligator River produced suffering on nonhuman animals, this is a moral prejudice to consider ...
