As a matter of fact, yes. Did you read the comment this was a response to?
But OK, I went back and reread it. I found one unsupported statement:
"But Atlantic mackerel and some populations of Atlantic herring have dropped to a fraction of their former levels. Many stocks are now in the critical zone—meaning that serious harm is likely occurring to the stock—and in some cases, have been that way for decades."
And yet, I cited some authoritative data from agencies that are in a position to know. Those agencies say the species are not endangered.
