It really depends. I think there are cases where the ecosystem is so sensitive that may be the case, but it really is on a case-by-case basis, so I think it would be speculative of me to say one way or the other. The reality is that, with the proper ecosystem-based approach, you can determine what the right mitigation measures could be. One of those might be moving the path that a ship follows, but you need a specific example, otherwise I'd be speculating.
