The correlation between Bieber and the salmon is easily as strong as the correlations Morton attempts to make.
Ms. Morton doesn't seem to have a grasp on the very basic idea that adding up half-truths doesn't result in the whole truth.
While I do
get your whole "correlation does not mean causation" argument, at some point you are going to have to accept that, because a strong correlation is
a sign of a causal relationship (it may not be the only
sign, but it is
a sign, so that while not all correlations are causal, all causal relationships are correlated), the correlation between the arrival of open net salmon farms on the main coastal migration routes of wild salmon and the decline in productivity of wild salmon is more likely
to be found to be a result of a causal relationship than is the birth of Justin Beiber and the decline of the wild salmon. You should have just stuck to the correlation between the expansion of Alaska salmon ranching and the decline in productivity of wild salmon. That correlation at least has a chance of being found to be causal in nature.
