Economic Importance for Humans: Positive
Penguins have been hunted for their blubber, which can be purified to oil and used for fuel. Hundreds of thousands of penguins were killed for their blubber, with some breeding colonies becoming obsolete. Gentoo skins are also collected and used to make caps, clothes, slippers, and purses. In the late 1980's, egg collecting was popular by sailors and by locals. These eggs also were consumed in large quantities.
