The 19th Century was a popular time for the whaling industry, particularly on the Falklands Islands. Whalers needed fuel in order to render whale blubber into whale oil, which would then be sold. But a lack of trees in the area meant that using wood to keep a fire going would not be not a sustainable option. However, there was another plentiful resource that made a suitable fuel; penguins.
This is an unfortunate truth. Penguins have highly flammable fat under their skin and they are quite docile in nature, making them easy to catch. Whalers burned them by the thousands, and the population of penguins in the Falklands Islands plummeted until there was a devastating change to their environment in the 1980’s; the Falklands War.
