Antarctic Wildlife Welfare and Climate Threats

Antarctic wildlife faces unprecedented threats from climate change and human activity. The welfare implications of a warming Southern Ocean are vast and underappreciated.

Key Facts

Antarctic sea ice reached a record low extent in 2023, affecting breeding success of penguins, seals, and seabirds
Emperor penguin colonies have suffered catastrophic breeding failures - in 2023, four of five Weddell Sea colonies recorded zero chick survival
Krill - the keystone prey species - are declining in some Antarctic regions as sea ice reduces
Fishing vessels operate in Antarctic waters targeting toothfish and krill, both critical to ecosystem welfare
Plastic pollution has now been found in the gut contents of Antarctic seabirds
The Antarctic Treaty and CCAMLR provide some protection but fishing pressure remains a concern

Welfare Considerations

Antarctic wildlife welfare is a scale problem: we are talking about the potential suffering and death of millions of penguins, seals, and seabirds due to ecosystem disruption caused by greenhouse gas emissions. Emperor penguins that reach breeding sites to find unsuitable sea ice conditions face starvation and reproductive failure after long migrations. Leopard seals, orcas, and seabirds all depend on krill-based food webs that are increasingly stressed. Individual animals experience real suffering from starvation and failed reproduction. The primary welfare intervention is climate action - reducing greenhouse gas emissions - but fisheries management in Antarctic waters also has immediate welfare consequences.

What You Can Do

Reduce your personal carbon footprint through diet, transport, and energy choices
Support climate policy advocacy organisations working on emissions reduction
Choose seafood certified by the Marine Stewardship Council and avoid Antarctic krill supplements
Donate to British Antarctic Survey and similar research organisations
Raise awareness of Antarctic ecosystem collapse among your networks
