In a cover story for the New York Academy of Sciences publication "The Sciences", Tobias called for an Antarctic World Park, citing threats to the potential area for large-scale habitat preservation. He released a 1987 PBS film entitled "Antarctica: The Last Continent" with a similar topic, proposing the creation of an "international park" in Antarctica similar to national parks in the US. According to "The Christian Science Monitor", the film explores "the discovery of Antarctica and the multinational claims to ownership."
