For years, many marine biologists have argued that the floating, open-ocean net pens that produce billions of pounds of salmon per year also generate pollution, disease and parasites.
In some places in western Canada, the open-ocean salmon farming industry has been blamed for the collapse of wild salmon populations in the early 2000s — though other research has challenged that claim.
If reality TV has a redeeming value, it's that it teaches you to be suspicious of claims that you're seeing real people doing real things. This is especially so in an age when memoirs bristle with made-up events, and everyone from the Kardashians to the Obamas orchestrate their media coverage.

In Poems to Learn by Heart, Kennedy stresses the importance of memorizing poetry and presents a collection of poems that she believes everyone should internalize.
"I think there's something in it for all ages," she tells NPR's Neal Conan. "I realized this shouldn't be just for kids because older people are the ones that are really working on keeping their memories going strong."
This is TALK OF THE NATION. I'm Neal Conan, in Washington. Technology's already changed our lives in ways we couldn't have imagined just a few years ago, and now seems ready to reinvent our future.
