Hats hitting the runway in Canada to honor a visit by Will and Kate include this wacky one, demonstrating a duck covered with tar from a toxic lake.
We also have surprising recipes to make on the grill, bad news for beaches, the best new ideas from Dwell On Design in Los Angeles, digital textbooks hitting classrooms, and more in our roundup of the best photos on TreeHugger this week.
Tar and Feathers
Design and Architecture writer Lloyd Alter says: Will and Kate are visiting Canada and Environmental Defence
is hitting the runways with a series of hats that describe Canada today, a very different place from when Chuck and Di visited 20 years ago.
My favourite is Tar and Feathers, "To mark the day Canada achieved infamy when a flock of ducks mistook a massive toxic lake in the tar sands for a good place to land."
