I have a concrete example if you would like.
In terms of the reefs, they are in a network. Networks, you've all heard, give resiliency and size. With climate change, you can't predict. You don't know if one area will be better than another. Because the recovery of populations might depend upon a new MPA you might make up at Chatham Sound, one should be open and forward-thinking in order to continue such a network. These kinds of regions could be influenced by low oxygen that comes up from the deep ocean as climate warms. You never know which patch might be the feeder patch that will sustain new reefs. You need to think a bit broadly.
