Ocean under pressure

Each year, the ocean faces more (and more complex) challenges, such as:

  • climate change and extreme weather
  • biodiversity decline
  • illegal, unreported and unregulated fishing
  • marine pests (plants and animals that move outside their normal range and disrupt the natural ecosystem)
  • pollution
  • a dynamic ocean economy that continues to change and develop.

Activities on land can also stress ocean ecosystems if they’re not managed well. These activities can include:

  • run-off from industry, agriculture, towns and cities
  • pollution and marine debris (such as light, noise, waste and plastic, and greenhouse gases)
  • mining and energy operations
  • coastal development.

We’re still learning how these pressures interact and compound. This is a challenge for sustainable management of our ocean.

Research by the High Level Panel for a Sustainable Ocean Economy has found that declining ocean health could cost the global economy:

  • more than $622 billion annually by 2050
  • up to $3.1 trillion annually by 2100.

Pressures on the ocean affect all of us, especially people who rely on it for their:

  • livelihoods
  • culture
  • health and wellbeing.

Marine industries are facing challenges such as:

  • competition for space from existing and new industries
  • evolving laws and regulations
  • species migrating to cooler waters because of increasing temperatures.

To thrive, these industries also need the goodwill and support of:

  • local communities
  • governments
  • investors.

All ocean users have a shared interest in taking the pressure off our ocean. This includes everyone from governments and business to occasional beachgoers.

Sustainable use will safeguard the ocean to ensure:

  • the future of marine industries
  • the prosperity of coastal communities
  • the continuing richness and vitality of ecosystems
  • future generations can enjoy the ocean’s benefits, beauty and wonder.
