North Atlantic right whale population estimateFacebook monthly active users
As Facebook grew from 1.4 billion to 2.9 billion monthly active users between 2015 and 2022, the North Atlantic right whale population declined from around 500 to fewer than 340 individuals, producing a -0.97 correlation that marine biologists have declined to weaponize publicly, showing admirable restraint. One does not wish to suggest that Facebook is killing whales, but one notes that the data has raised the question and then declined to answer it. The whales, having no Facebook accounts and therefore no mechanism for filing a complaint, have taken the philosophical approach of simply becoming rarer.
North Atlantic right whale populations declined from roughly 500 in 2015 to under 340 by 2022, driven by entanglement in fishing gear, vessel strikes, and climate change affecting their food supply — these are well-documented and thoroughly studied threats entirely unrelated to social media. Facebook's monthly active users grew steadily through the same period due to global internet adoption, particularly in developing markets. The inverse correlation is coincidental; the whale population decline reflects specific ecological and industrial pressures while Facebook's growth reflects global connectivity trends. The two trend lines happen to be moving in opposite directions during the same window.
The most haunting spurious correlations are the ones where one of the variables is actually an ecological crisis. The numbers are unrelated; the tragedy is not.
