Going back to you, Dr. Ban, what about protection of the benthic environment? I gather there's an MPA dealing with the sponge reefs off the coast of B.C. I strongly support directed conservation that has very clear goals. This benthic community is obviously worthy of protection, but why wouldn't, for example, commercial shipping be allowed in that area? I don't know what the depth of the water is, but it's probably fairly obvious that commercial shipping is very important to the economy of B.C. and indeed the economy of Canada. My own province ships all kinds of wheat and canola from ports off B.C., and the shipping is absolutely critical.
So why couldn't you have both in a marine protected area, have the benthic community be protected and at the same time commercial shipping be allowed to continue in order to support the economy?
