The issue people who disfavor the MPAs are focusing on is whether the benefits of the MPAs outweigh the negative socio-economic impacts that they will invariably have. I think (but of course can't prove), like you, that they do. However, I also don't fish, spearhunt, eat fish or rely on the fishing industry for my livelihood, so it's easy for me to place the emphasis in the equation on the health of ecosystems over the concerns of people who fish and rely on fishing. If I relied on fishing, I would undoubtedly place more emphasis on maintaining access to productive spots; I recognize that a lot of people do like to fish and rely on fishing to live, and I understand that people in those camps would disagree with me. I respect their right to do so and think their voices need to be heard, because, frankly, a lot of the people who fish/hunt here know these waters better than most policy wogs.
Without getting all Rodney King on everyone, my hope is that the different stakeholders and interest groups (continue to?) cooperate and listen to each other to the extent possible, because if we can't figure out how to balance competing interests here in California and minimize socio-economic disruption while rebuilding seriously damaged ecosystems, how can we expect countries with seriously competing interests to cooperate and develop realistic and effective international and transnational environmental policy, which the world's oceans (among other things) desperately need?
