First Cop15, now the high seas treaty: there is hope for the planet’s future

Many agree that strides have been made in protecting biodiversity and the oceans - but much remains to be done

Late last Saturday in New York, exhausted negotiators reached a landmark agreement on protecting life on Earth: the high seas treaty, the second big environment deal in just three months after Cop15, the biodiversity summit in Montreal. The moment, nearly two decades in the making, overwhelmed the president of the conference, Rena Lee, who cried as she announced that a deal had been done.

On paper at least, countries nearly have a complete strategy for action on the three planetary crises of our era: the climate emergency, biodiversity loss and pollution. Governments are still negotiating a UN agreement on plastics pollution, with another round of talks scheduled in Paris this year. But world leaders, business heads - all of us - know what we must do in the next decades to avoid disaster.
