The causes described for the decline are entirely at the hands on humans and span from direct causes such as hunting to indirect causes such as harvesting krill to fee factory farmed fish. The article contains a number of statistics and a quote from a biologist from the Whale and Dolphin Conservation Society, but the saddest part of the article deals with the blue whales. In the 19th century there were nearly a quarter of a million, but there are only estimated to be 2,200 remaining. The article ends with a passage from Yves Paccalet about an overlooked cause for the decline:
