Detailed explanation-1: -Since 1970 krill populations have fallen by 80% in the Southern Ocean surrounding Antarctica. Because krill require sea ice to reproduce, shrinking sea ice from climate change has made it more difficult for them to breed.

Detailed explanation-2: -Krill populations have declined by 80 percent since the 1970s. Global warming has been blamed for part of that decrease because the ice that is home to the algae and plankton they feed on is receding. Campaigners say recent developments in fishing technology are worsening the problem.

Detailed explanation-3: -Climate change and industrial-scale fishing is impacting the krill population with a potentially disastrous impact on larger predators, say scientists. First images of creatures from Antarctic depths revealed.

Detailed explanation-4: -Unfortunately, Antarctic krill populations appear to be declining. A new study has found that climate change is driving Antarctic krill southward and changing species distribution which could have an irreversible impact on the Southern Ocean food web.

Detailed explanation-5: -Penguins, seals, fish and whales in the Southern Ocean all depend on krill for food. That’s because krill lie at the base of the Southern Ocean food web. Thus declining krill populations will affect them all, including these Gentoo penguins.
