Renewing the Earth

Although the Bishops acknowledge the scientific uncertainty and controversy surrounding concerns for accelerated rates of climate change, diminishing biodiversity, deforestation, and the implications of widespread dependencies on fossil fuels, they nonetheless identify environmental integrity as a moral imperative for today. Elsewhere, arguments for a right to development, particularly for the nations of the “third world,” have increasingly been tempered by concerns for long and short term environmental costs. Thus, Catholic social teaching increasingly promotes sustainable development, i.e., "meeting the needs of the present without compromising the ability of future generations to meet their own needs." (Brundtland Commission, 1987).

Still, the Judeo-Christian tradition (which they admit has sometimes been used to justify human exploitation of the earth) contains rich resources for the promotion of ecological responsibility. For example, the Hebrew Scriptures describe creation in terms which give rise to a demand for right-relation, not only between persons, but between the human and non-human in creation. The Bishops go on to identify seven core principles or themes in CST in service of ecological conversion:

an understanding of the universal purpose of created things, which requires equitable use of the earth's resources;

a conception of authentic development, which offers a
