No flag can claim the high seas. As a result, life in the two-thirds of the oceans beyond any country's territorial waters faces many, largely unregulated threats including overfishing and the emerging deep-sea mining industry. This week, United Nations delegates met to negotiate the first ever high-seas conservation treaty, and marine scientists moved to influence the outcome. One research group unveiled maps envisioning global networks of marine reserves. Other teams are working on maps of their own to show policymakers what new high-seas reserves could look like. The United Nations expects to finalize the treaty next year.
