Unity, protection and responsibility, i.e. tawhid, khalifa and akrah: the three central concepts of Islam, are also the pillars of Islam's environmental ethics. The relationship between humans and the environment is part of social existence, an existence based on the fact that everything on earth worships the same God. Humans are expected to protect the environment since no other creature can perform this task. Humans are the only beings to whom God has “entrusted” the responsibility of caring for the earth. Social responsibility is another area highlighted in both Islam and Christianity. Both religions believe that the concept of social responsibility implies that individual members of society work together to meet the general needs of society as well as the individual needs of its members, and that they work together to protect society from harm. Both “God” and “Allah” call us to respect the earth, to seek a more just society, to include the forgotten, to be peacemakers and to build the common good. Both Christians and Muslims believe that social responsibility helps achieve this goal
