Australian supermarket giants Coles and Woolworths have announced they will stop selling dietary supplements containing krill oil. This decision follows growing concerns about the sustainability of krill harvesting in the Antarctic Ocean. Krill are a crucial food source for whales, penguins, and other vital species in the Antarctic ecosystem, and their populations are facing increasing pressure. Commercial fishing operations harvest krill to supply the growing market for Omega-3 fatty acid supplements. Environmental groups have welcomed the move, arguing it will reduce demand and aid krill stock conservation. Both Coles and Woolworths stated their commitment to responsible sourcing and protecting marine environments influenced their choice. The retailers hope this sends a message to the supplement industry regarding sustainable practices.
