The United Nations’ project Biodiversity Beyond National Jurisdiction (BBNJ) is a spinoff of the Law of the Sea.  The UN explains the BBNJ here,  part of which follows below:

“In its resolution 72/249 of 24 December 2017, the General Assembly decided to convene an Intergovernmental Conference, under the auspices of the United Nations, to consider the recommendations of the Preparatory Committee established by resolution 69/292 of 19 June 2015 on the elements and to elaborate the text of an international legally binding instrument under the United Nations Convention on the Law of Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction, with a view to developing the instrument as soon as possible.
