UNAOC understands that censoring media which is perceived as potentially harmful will not effectively curtail the spread of media messages appealing to youth with violent extremist narratives.

Women play a variety of roles in complex, multitrack peace processes. They can sit at the formal negotiating table, on a technical committee or subcommission, or they can be outside the talks engaged as civil society actors in following developments. All of these roles are critical.

Sustainable Development Goal 14, Life Below Water, does not end with the oceans, but instead, starts with the oceans. By protecting our oceans, we are able to work towards living healthier more sustainable lives with fewer contaminants in our food, harnessing natural energy resources such as wind and tidal energy, and reducing the effects of climate change.

As the United Nations Goodwill Ambassador for Biodiversity, I have travelled the world speaking to people about the defining challenge of our generation: bringing the way we live into a sustainable interaction with our planet.

Oceans, however, happen to be borderless and are also unevenly distributed across the planet. We cannot protect our share of the ocean with walls; instead, we must cooperate in a spirit of solidarity if we are to succeed in preserving and protecting the water that we have at our joint disposal. We must work together with our closest neighbours and cooperate at a global level, between countries.

The Ocean Conference will be humanity's first universal moment of accountability to remedy the woes we have put upon the Ocean. We will come out of the Conference armed with a broad set of partnerships, commitments and measures to be put into action.

We cannot continue, let alone accelerate, the changes we are causing to ocean ecosystems. That is why the United Nations system is working with Governments and international, private sector and civil society organizations to strengthen governance structures and promote the implementation of international legal instruments and various management tools, such as integrated coastal zone management and marine spatial planning, and to facilitate a coordinated approach to the application of law and policies for environmental protection and sustainable economic development.

Despite their critical role in sustaining life in this world, our oceans are increasingly threatened, degraded or destroyed by human activities, reducing their ability to provide crucial ecosystem services.

This special double issue of the UN Chronicle, under the theme Our Ocean, Our World, explores many of the problems facing the marine ecosystem, with articles by 23 experts and eminent personalities actively engaged in finding solutions.

On my extensive voyages across the globe I have discovered that it is the same story everywhere—not only in the gyres, but all the way from the Tropics to the Arctic. Our oceans have become a fine soup of plastic fragments.
