Religion and spirituality are related to human beings alone, not relevant to any other life on this earth.
Religion is the common behaviour and practices of a group of people based on some principles defined by scriptures, epics, rituals, customs, traditions and cultural practices. A religion may not be subjected to reasoning and experiences to confirm all that is said and practised. A spiritual person can be religious too.
Religion plays an important role in directing, leading and uniting communities for achieving the good things in society.
There are so many religions all over the world. Each religion is based on some of the fundamental truths and beliefs. Within the religion, how to preach things which were not imagined when the religion was formed, say certain practices in using the resources sustainably. The way respective religions are interpreted by people is to their own interest. It is also sometimes a cause of concern.
Religion is a belief for common development. It also brings in the common understanding of living in a society harmoniously. All religions should preach sustainable development.
