World Environment Day, established by the United Nations, is commemorated each year on 5 June, to stimulate worldwide awareness of the environment and thereby enhance political attention and action.
Eco-Sunday (Ecological Sunday) is observed to remember our responsibilities as stewards of God’s creation. Ecology is a study of inter-relationships between organisms and their environment. The word ‘Ecology’ is derived from the Greek word ‘oikos’ which means house or habitation. Ecology therefore refers to the earthly habitation which human beings share with other living beings and specifically to the mutual relations between organisms and their environment
