Book excerpt: Freedom for the Seas in the 21st Century brings together leading international experts on marine policy to address current threats to the health of the seas and to offer new approaches to the challenge of protecting our marine environment. The paradigm presented is one of ocean governance rather than of law or policy; it challenges the prevailing concept of "freedom of the seas" and calls instead for a governing notion of "freedom for the seas" where the primary goal is the protection of ecological vitality. Topics covered include: *strategies for controlling ocean pollution *regulation of high-seas fishing *defects in current deep seabed mining regulatory provisions *threats to the marine environment posed by military activities
