Oceans 21

Oceans 21, a series focused on the sustainability of our ocean, started by The Conversation, which is an independent source of news and views. In this in-depth analysis, five ocean profiles deep-dive into ancient trade networks across the Indian Ocean, the scourge of plastic pollution in the Pacific, light and life in the Arctic, Atlantic fisheries and the Southern Ocean's impact on the global climate.

Global warming, climate change, ocean acidification and overfishing are all having a major impact on the health and wealth of our oceans. And it is all connected. There is a lot to learn more every day about the complexity of the systems that drive life below the water. New research is revealing the extent of this damage, but also offering new ideas and solutions.

The world's ocean takes up more than 90% of the excess heat from burning fossil fuels and a third of the additional CO₂. It produces most of our oxygen, helps shape the winds that influence our weather, and provides food and income for millions. The Arctic is warming faster than any other place on Earth, causing dramatic change in the coldest ocean.
