Marine Protected Areas
To me it's common sense: having protected areas in the ocean benefits everyone. The fish and other creatures that need a safe spot to feed, breed and live. The ocean users who get to watch & enjoy this life. The fishermen who depend on this resource. And the planet which needs healthy oceans to function.
However it seems this is not common sense to everyone here in Australia, so I'm going to start sharing some of the science that backs this up. Here's a couple of facts to get started. I'll keep adding on here over the next few months so check back in if you're looking for some more science to back up your arguments in support of marine sanctuaries!!
