Krill found to break down microplastics – but it won't save the oceans

Digestion of plastic into much smaller fragments ‘doesn’t necessarily help pollution’, Australian researchers say

A world-first study by Australian researchers has found that krill can digest certain forms of microplastic into smaller – but no less pervasive – fragments.

The study, published in Nature Communications journal on Friday, found that Antarctic krill, Euphausia superba, can break down 31.5 micron polyethylene balls into fragments less than one micron in diameter.

'Mega-colonies' of 1.5 million penguins discovered in Antarctica

The discovery shows the remote area is a vital refuge for wildlife from climate change and overfishing and should be protected by a new reserve, say scientists

Huge “mega-colonies” of penguins have been discovered near the Antarctic peninsula, hosting more than 1.5 million birds. Researchers say it shows the area is a vital refuge from climate change and human activities and should be protected by a vast new marine wildlife reserve currently under consideration.

The huge numbers of Adélie penguins were found on the Danger Islands in the Weddell Sea, on the east side of the Antarctic Peninsula. It is a difficult place to reach and has seldom been visited. But scientists, prompted by satellite images, mounted an expedition and used on-the-ground counts and aerial photography from drones to reveal 751,527 pairs of penguins.

Antarctica's king penguins 'could disappear' by the end of the century

Climate change and overfishing could push the region’s king penguin populations to the brink of extinction, a new study shows

Rising temperatures and overfishing in the pristine waters around the Antarctic could see king penguin populations pushed to the brink of extinction by the end of the century, according to a new study.

The report, published in the journal Nature Climate Change, found that as global warming transforms the environment in the world’s last great wilderness 70% of king penguins could either disappear or be forced to find new breeding grounds.

Decline in krill threatens Antarctic wildlife, from whales to penguins

Climate change and industrial-scale fishing is impacting the krill population with a potentially disastrous impact on larger predators, say scientists

The Antarctic, one of the world’s last great wildernesses and home to animals such as whales, penguins and leopard seals, is being threatened by the plight of an animal just a few centimetres long, according to scientists.

Researchers and environmental campaigners warn that a combination of climate change and industrial-scale fishing is threatening the krill population in Antarctic waters, with a potentially disastrous impact on larger predators.
