Governments have gathered at the third UN Ocean Conference (UNOC 3) in Nice, France, to renew and form tighter pledges to protect the Earth’s lungs. Nutrition Insight dives into the regulations and sustainability of Antarctic krill trawling amid rising public scrutiny and climate-stressed krill populations, with the British Antarctic Survey (BAS). Krill is a source of eicosapentaenoic (EPA) and docosahexaenoic acids (DHA), astaxanthin, and phospholipids used to make supplements and nutritional ingredients for humans and pets. This year’s UNOC 3 theme is accelerating action and mobilizing all actors to conserve and sustainably use the ocean.
