The countries of the ASEAN region have important roles to play in tackling the global problem of marine plastic waste.
As more and more plastic trash permeates the oceans, fragments are making their way into fish and shellfish – and potentially into humans.
Polluted oceans don’t just harm wildlife, they are a source of ill health for humans too.
Marine protected areas will be important for achieving the ocean Sustainable Development Goals.
A high seas treaty could help rebuild populations – but time is running out.
There are more viruses in the ocean than stars in the Milky Way – and they’re fundamental to Earth’s biodiversity.
Despite their enormous value, mangroves are being removed at an alarming rate. A new tool aims to help communities reverse mangrove loss and tap into conservation programs and funding.
Microplastic pollution is a global issue, but where do they come from and how are they transported across the ocean? A new study finds polyester microfibres are common throughout the Arctic Ocean.
Whales are rediscovering their old haunts in the Arctic and Southern oceans after centuries of hunting.
Belugas use sound to communicate, navigate the dark marine environment and find food. But climate change is opening up Arctic waters to more sound, and could affect the health and survival of belugas.
Global leaders pledged to protect 10% of the oceans by 2020. We’re nowhere close and the goal has proven particularly challenging to achieve in international waters.
