Did you hear about the brouhaha with Adidas and kangaroo leather in California? Federal law allows the use of kangaroos in Adidas’ products and others, part of the effort to cull Australia’s overpopulation of the cute little buggers, but California state law forbids sale of kangaroo products. This weekend, from Friday through Sunday, animal rights organization Viva! USA is kicking off a boycott of Adidas at the USA headquarters (5055 N Greeley), planning to confront them with a video called “Killing for Kicks.”
