The encyclical letter Laudato Si is available here on the Vatican website.
Pope Francis’ first chapter is largely held to be the message for the masses, but he does poke at moral issues such as waste.
22. These problems are closely linked to a throwaway culture which affects the excluded just as it quickly reduces things to rubbish. To cite one example, most of the paper we produce is thrown away and not recycled. It is hard for us to accept that the way natural ecosystems work is exemplary: plants synthesize nutrients which feed herbivores; these in turn become food for carnivores, which produce significant quantities of organic waste which give rise to new generations of plants.
Our God-given universe exhibits a genius in its balance. We are far from achieving anything like it, despite our prowess in technology:
But our industrial system, at the end of its cycle of production and consumption, has not developed the capacity to absorb and reuse waste and by-products. We have not yet managed to adopt a circular model of production capable of preserving resources for present and future generations, while limiting as much as possible the use of non-renewable resources, moderating their consumption, maximizing their efficient use, reusing and recycling them. A serious consideration of this issue would be one way of counteracting the throwaway culture which affects the entire planet, but it must be said that only limited progress has been made in this regard.
Consider that we have only a few decades of cell phones to go, unless we find renewable resources to provide us that handy, instant communication.
