Antarctica, the high seas and deep seabed, the atmosphere, and space are increasingly accessible — and exploited — resource domains. Collectively known as the global commons, they represent a new and profound challenge for international law and institutions. In The Global Commons, Susan Buck considers the unique physical, legal, management, and policy problems associated with these areas. The book is a clear, useful introduction to the subject that will be of interest to general readers as well as to students in international relations, international law, and environmental law and policy.
