The encyclical letter Laudato Si is available here on the Vatican website.
185. In any discussion about a proposed venture, a number of questions need to be asked in order to discern whether or not it will contribute to genuine integral development. What will it accomplish? Why? Where? When? How? For whom? What are the risks? What are the costs? Who will pay those costs and how?
Questions such as these are considered threatening. Certainly in church circles, there are a lot of leaders who disdain discernment that includes difficult queries.
In this discernment, some questions must have higher priority. For example, we know that water is a scarce and indispensable resource and a fundamental right which conditions the exercise of other human rights. This indisputable fact overrides any other assessment of environmental impact on a region.
