Australia needs to drop the deception that square kilometres say anything meaningful about conservation.
Marine protected areas will be important for achieving the ocean Sustainable Development Goals.
Partially protected areas don't have more wildlife than unprotected areas. They consume conservation resources and occupy space that could otherwise be allocated to more effective protection.
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.
The Southern (Antarctic) Ocean is our planet's primary storage of heat and carbon, and it's home to extraordinary life forms, from tiny algae and spineless creatures to penguins, seals and whales.
The Blue Belt is a network of marine protected areas 17 times larger than the UK.
Most existing MPAs are in distant and largely empty waters. Expanding them where it counts will meet a lot of resistance.
More than 280 women in STEMM call for a marine protected area to be established in the waters of the Western Antarctic Peninsula.
Multiple ocean industries are rapidly growing, but efforts to protect vulnerable habitats are stalling.
The latest incident highlights a mismatch between ocean law and marine ecosystems.
Biodiversity is often highest in places with human activity. The fishing industry has shown we can often have it both ways: maintain important livelihoods while protecting precious marine life.
Without understanding which fish species and habitats local fishers rely on, export bans can do more harm than good.
Fish larvae will swim towards the sounds of a desirable reef, but degraded reefs cannot be rebuilt on sound alone.
Although less well known than its cousins, coral reefs and mangroves, seagrass plays a crucial role in climate change mitigation.
Fish can't read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
Even the remote open ocean offers no escape from industrial fishing for sharks.
New Zealand has one of the world's largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.
Strictly enforced no-take marine areas benefit everyone, from the fish to fishers.
A new network of 20 sites have been declared as marine protected areas in South Africa.
Countries can protect biodiversity and recognize Indigenous peoples as conservation partners.
