—and it's an excellent one.
We can come back and talk for ages on that, but I would point again to the science. We've looked at the science, and we need to do more. We've looked at large areas of the oceans and identified where the corals and sponges are and where the protected areas are.
We actually identify vulnerable marine ecosystems, and that's kind of been the approach: what ecosystems really need protection to enable the broader ecosystem to function effectively. That's really been the approach with the ecologically and biologically significant areas, or EBSAs.
I would also say that an ecosystems approach with respect to fisheries and oceans management is probably something we've been better at talking about than doing, but we are, with more and more science, getting into that world. This work that we're doing now on protected areas will help us get there as well.
It is a huge challenge to be able to manage species one at a time. It is a gigantic challenge to be able to manage an ecosystem and understand the relationships between the trophic levels and the relationships between the various species. That is a work in progress and something that we're committed to moving forward on.
