“ 3.3.4.1
Impact by Fallen Objects
Direct strikes by debris from Starship are extremely unlikely for all species of concern, fish, sea turtles, and marine mammals. This is due to the small size of the components as compared to the vast open ocean.
If debris from the vehicle struck an animal near the water's surface, the animal would be injured or killed.
As stated in the 2022 PEA, given the low frequency of the Starship/Super Heavy ocean descent and landing operations, and the fact that marine wildlife, marine mammals, and special status species spend the majority of their time submerged as opposed to on the surface, it is extremely unlikely they would be impacted. The relative occurrence of these animals at the ocean surface, spatially and temporally, combined with the low frequency of the Proposed Action, reduce the likelihood of impacts to extremely low. Additionally, there are no known interactions with any of these species after decades of similar rocket launches and reentries. Further, the projected landing areas for both Super Heavy and Starship are well offshore where density of marine species decreases compared to coastal environments and upwelling areas (FAA 2017).”
Pretty much every subsection of the report regarding risk to biological life ends on a similar note.
