During the philosophical symposium on Ecology and Religion - I should add, perfectly well coordinated and organised by Fr Wilson... hats off to him! - Fr Devadas made a very interesting and practical suggestion. Speaking during an ongoing debate about the role of the Church in the ongoing ecological crisis, he suggested that during major feasts and celebrations, the faithful could be given a sapling - blessed by the Priest - to take home and take care of. It would be a 'living gift from a living God'. That is great idea!! Rather than give medals and statues and so on, a plant is a living gift. People would naturally begin to see nature as God's gift and not something merely to be used for personal benefits.
Good suggestion too to link the Church, God, Christianity and nature... of course with human beings!
