Russia and China have blocked proposals for Marine Protected Areas (MPA) in the region for decades. Members of the Commission have called for member states Australia, the US (really?) Japan, and others to condemn Moscow’s actions. Of note: Leonid has conducted research for the Commission since 1983 and as a Ukrainian scientist since 1994. He and family reside in Kerch, Crimea. According to several scientists familiar with his work: His contribution t0 the Commission is........
