Marine mammals are a food source in many countries around the world. Historically, they were hunted by coastal people, and in the case of aboriginal whaling, still are. This sort of subsistence hunting was on a small scale and produced only localised effects. Dolphin drive hunting continues in this vein, from the South Pacific to the North Atlantic. The commercial whaling industry and the maritime fur trade, which had devastating effects on marine mammal populations, did not focus on the animals as food, but for other resources, namely whale oil and seal fur.
Today, the consumption of marine mammals is much reduced. However, a 2011 study found that the number of humans eating them, from a surprisingly wide variety of species, is increasing.[1] According to the study's lead author, Martin Robards, "Some of the most commonly eaten animals are small cetaceans like the lesser dolphins... That was a surprise since only a decade ago there had only been only scattered reports of this happening".[2]
