World leaders are convening in Nice, France for the United Nations Oceans Conference from June 9-13, addressing the urgent threats to oceans from climate change, pollution, and resource overuse. The conference aims to finalize key agreements and mobilize action towards sustainable ocean management, with a focus on UN Sustainable Development Goal 14. Key figures like President Emmanuel Macron and Brazilian leader Luiz Inácio Lula will attend, with expectations for new marine protected areas and funding commitments. However, significant funding gaps remain for effective ocean protection.
