When God gave humankind dominion over the earth he may not have known exactly what we would be able to do with it. The technical capacities to which the production and reproduction of our everyday life have given rise have grown at an astonishing and, it seems, ever-increasing rate. The instruments that we use to do work on the world have become sharper and more refined, and the implications of human interventions in the nonhuman environment are much more far-reaching than could have been imagined even forty years ago. It has become something of a cliche to say that our technical abilities have outstripped the wisdom to know when, where, and how we should appropriately use them, but techniques such as genetic engineering invite the dusting-off of the cliche and the asking of the question implicit in it: We know we can splice genes, but should we splice them? We might of course come to the conclusion that we should only splice some of them some of the time, but even arriving at that conclusion presupposes that the ethical question has been asked and answered.
1. There is no need to distinguish between ethical and environmental-ethical for the moment.
2. To the extent that some scientific research is carried out ‘for its own sake’ this is an inaccurate formulation–but it will do for present purposes. In any case, discoveries made after research ‘for its own sake’ will often have practical implications, and so the ethical questions will arise at some point or other.

14. A distinction must be drawn between ‘human-centered’ and ‘human-interested.’ A human-interested ethic is one in which human interests automatically override those of the nonhuman natural world (or certain bits of it). A human-centered ethic is one which recognizes that ethics will derive from human beings because only humans can make moral judgments (so far as we know), but that human interests need not automatically override those of the nonhuman natural world.

67. Although of course these risks need also to be taken into account, and have been the subject of intense debate for as long as genetic engineering has been practised.
