"The sustainable management of this natural resource is a challenge for the social, economic and environmental order, but especially because of its ethical nature, starting from the principle of the universal destination of the goods of the earth," says the Pontifical Council for Migrants and Itinerants in a message released on 11 July for the forthcoming World Day of Tourism.
"We are invited, therefore, to promote eco-tourism, environmentally friendly and sustainable, that can surely promote the creation of new jobs, support the local economy and reduce poverty," the message says.
"More determination from politicians and entrepreneurs is necessary," the Vatican message continued, adding there needed to be "binding, specific and verifiable commitments" to ensure responsible use and just distribution of water.
World Tourism Day is marked on 27 September.
