“The lack of concrete action to address threats adversely affecting cetaceans in our increasingly busy, polluted, over-exploited and human-dominated seas and major river systems, means that many [populations], one after another, will likely be declared extinct within our lifetimes,” the statement warns. “Whales, dolphins, and porpoises are seen and enjoyed all over the world, and are valued as sentient, intelligent, social, and inspiring species; we should not deny future generations the opportunity to experience them. They are also sentinels of the health of our seas, oceans, and, in some cases, major river systems and the role of cetaceans in maintaining productive aquatic ecosystems, which are key for our survival as well as theirs, is also becoming clearer.”
