Now forbidden, African penguin guano was once excavated and processed into fertilizer and their skins were manufactured into gloves.
African penguins provide a substantial source of guano. At one point, guano was excavated from rookeries by humans, processed, and made into fertilizer, which was then sold around the world. Guano is now forbidden in fertilizer, which has reduced the economic importance of black-footed penguins for humans.
Penguin skins have also been used and sold as gloves.
