To Jane Young and her Forest and Bird cohorts. Hope you saw Saturday night news (October 14).
This showed the annihilation of Adelie penguin chicks in the Antarctic caused primarily by 300 metre to 400 metre fishing vessels slaughtering the krill fishery in the southern waters.
This overfishing has also affected New Zealand’s penguin species and fish stocks.
Krill is one of the main cornerstones of the ocean’s food chain, fed on by everything from whales, fish and birds, removed in vast quantities; the whole ocean’s eco-system fails, as results are showing.
Greenpeace, you are wasting your time chasing whalers around the ocean. In the near future, due to lack of whale feed (krill), whales will starve to death.

livestock and poultry feed, and increasingly for human food supplements.
Antarctic krill fisheries are regulated by the Commission for the Conservation of Antarctic Marine Living Resources - CCAMLR. In 2016 the regulations, based on biomass data gathered back in 2000, allowed for a total catch of 3.7 million tonnes. It seems unlikely that this would adequately take into account the needs of the many species of sea birds, seals and whales that depend on krill.
In the case of this year’s breeding failure of a colony of 18,000 Ade´lie penguins, however, it appears to be climate change rather than the krill fishery that was the major cause. Unseasonably extensive amounts of sea ice around the Antarctic territory of Ade´lie Land forced the adult penguins to travel further
