The recent RTÉ Christmas message from Archbishops Richard Clarke and Eamon Martin looked at our shared responsibility for our environment and climate. The Archbishops highlighted the Great Green Wall and Laudato Tree initiatives, to prevent desertification across 8,000 km (5,000 miles) in the Sahel, and encourage people in Ireland to plant trees here and sponsor the planting of more trees in this part of Africa. The initiative is improving food security, and creating jobs and a better quality of life in communities for millions of people who live along its path. The broadcast is an annual opportunity provided by RTÉ to communicate a Christian message to viewers and listeners. Many thanks to the teachers and students of the Royal School Armagh, St Catherine’s College, Armagh, and St Paul’s High School, Bessbrook, who contributed to the broadcast through music and a discussion with the Archbishops.
