UN chief warns against deep-sea mining "wild west," calls for regulation at Ocean Conference.

United Nations Secretary-General Antonio Guterres warned against treating the deep sea as a "wild west" at the UN Ocean Conference in Nice, France. He emphasized the need for regulation and conservation, as countries debate rules on mining the seabed for minerals and a global treaty on plastic pollution. French President Emmanuel Macron called for a moratorium on deep-sea mining, citing environmental concerns. The summit also saw commitments like a partial ban on bottom trawling in UK marine protected areas, aiming to protect marine life and combat overfishing.
