Goodbye, penguins!

The day may come when we’re advised during icy conditions to “walk like a penguin” and a growing number of people will not know what a penguin is.

CBS News correspondent Mark Phillips has been hanging out at the Palmer Station in Antarctica, which has been studying the Adelie penguin for years.

But in recent years the number of penguins has dropped by 85 percent, he reported this morning.

The penguins need sea ice. The sea ice season is three months shorter these days.

Scientists thought that maybe the penguins just moved farther south. They didn’t, apparently.

In other marine news, there’s a SPAM can on the bottom of the ocean, and Austin, Minn., must be so proud.
