14salmon.650.jpg A forthcoming study in Science shows that parasitic sea lice infestations caused by salmon farms are driving nearby populations of wild salmon toward extinction. Wild pink salmon have been rapidly declining for four years, reports SeaWeb. Author Martin Krkosek, a fisheries ecologist from the University of Alberta, expects a 99% collapse in another four years, or two salmon generations, if the infestations continue. The data are from the Broughton Archipelago, a group of islands 260 miles northwest of Vancouver, environmentally, culturally, and economically dependent on wild salmon.

This study and earlier studies by the same authors shows that sea lice from fish farms infect and kill juvenile wild salmon, raising serious concerns about net pen aquaculture in general. “It shows there is a real danger to wild populations from the impact of farms,” says Ray Hilborn, a fisheries biologist from the University of Washington, not involved in the study. “This paper is really about a lot more than salmon. This is the first study where we can evaluate these interactions and it certainly raises serious concerns about proposed aquaculture for other species such as cod, halibut and sablefish.”

If you must, eat wild Alaskan salmon.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
