This article describes how the Antarctic and Southern Ocean Coalition (ASOC) was formed and developed, how it contributed to the development of CCAMLR, the long campaign on a World Park instead of a minerals treaty, the negotiations of the Antarctic Treaty Environmental Protocol, and the movements to create Marine Protected Areas (MPA) in the Southern Ocean. In this article I also want to acknowledge the wonderful work and effort of the many people that have contributed to achieve these goals over the years.
