PRI's The World: 08/04/2016

The 2016 Summer Olympics gets underway on Friday. We check on the mood in Rio, and hear about all the residents there who were evicted from their homes to make way for Olympic venues. We also learn about an effort to protect grizzly bears in Canada's Great Bear Rainforest. And, we meet a depressed egg cartoon character that's captured hearts and minds in Japan, and beyond.
