Deletion of Seattle Marine Aquarium

Comment: Notable history as the first aquarium to display captive killer whales including Shamu. Sources are available (for example, http://www.historylink.org/index.cfm?DisplayPage=output.cfm&File_Id=2718 this website indicates there is a National Geographic Society article from 1973). Some of that notability will be negative due to protests -- but all content must certainly be revised to meet our policies on |neutral point-of-view and no |undue weight
