Economic Importance for Humans: Positive
Adelie penguins are often good indicators of climate change. Adelie penguins are beginning to inhabit beaches that were previously perenially covered in ice, suggesting warming of Antarctic environments. Adelie penguin colonies are highlights for ecotourism in the Antarctic.
From the eighteenth to the early twentieth century these penguins were used for food, oil, and bait. Their guano was mined and used as fertilizer. Now they are a protected species in most countries. (Ainley, 2002; Glausiusz, 2007; Grossman, 2003)
