I think there are two different questions there, and Zoe might be in a better position to answer part of it.
The questions around habitat protection and the flora and fauna of Sable Island and the protection of Sable Island itself are separate from any issues relating to oil and gas exploration. As far as I know, there isn't any particular necessity to protect habitat. I think at the moment it's about five or six kilometres offshore, and it hasn't posed any environmental difficulties. I know that aesthetically there will be some, but when you're on the ocean, things loom large generally.
One of the other members here might be in a better position to answer.
