Nuclear negotiations with Iran, social impact of World Cup, and meat production and the environment

The nuclear talks with Iran are at a crucial point. Iran has become very public with its proposals. There’s a July 20th deadline where the parties have the option of extending the talks for another six months. Joseph Cirincione is president of Ploughshares Fund, a global security foundation. He is the author most recently Nuclear Nightmares: Securing the World Before It Is Too Late. He'll tell us where he thinks the talks are headed.
Then, throughout the country in the lead up to the World Cup, Brazilians were protesting the sporting event, and the demonstrations continued through the final match. Part of the protests were aimed at FIFA, soccer's governing body. We'll talk to Dave Zirin, sports editor for The Nation and author of Game Over: How Politics Has Turned the Sports World Upside Down, about the future of FIFA and the tournament's impact on Brazil.
And, a study at Oxford University found that eating meat contributes significantly to an individual’s carbon footprint. The study was conducted by surveying the diets of 60,000 people. It found that meat eaters had the largest carbon footprint, then fish eaters, then vegetarians, and finally vegans had the lowest impact on the environment. Dr. Peter Scarborough worked on the study and is a head researcher at Oxford University. He joins us to tell us why cutting back our meat consumption can help reduce our negative environmental impact.
