“De-extinction” raises the prospects of both taking whiteout to some of our species’ careless past and recreating ecosystems that haven’t been seen in thousands of years. De-extinction raises myriad ethical and environmental issues. However, there are legal issues facing it & these depend on precisely how we de-extinct a species.
The authors make the argument that we can avoid some of these issues simply by being careful about if and how we designate any new species that arise from our de-extinction efforts. But the issues seem to be large enough that we might want to consider revising the laws and regulations in advance of the technology progressing much further. Otherwise, we run the risk of ending up with a species that, legally, we’re unsure what to do with.
