Corporations have edged into nearly every area of our lives, impacting decisions we make on a daily basis, from health care to the food we eat to the way we get our news and information. Today on GRITtv we take a look at a couple of places that corporate control is being challenged. The Internet has fundamentally changed the media landscape, allowing everyday people to have their voices heard and connect with one another in new and exciting ways. So it really shouldn't be surprising that corporations want to tighten their grip on the Web and our ability to disseminate information on it.  To explain the importance of Net Neutrality--maintaining a free and open Internet--we have Timothy Karr of Free Press, Gigi Sohn of Public Knowledge, and Karlos Schmieder of the Center for Media Justice. We tend to assume that our physical bodies are free from intellectual property claims, but a recent lawsuit by the ACLU shows us just how wrong that is. Medical research companies are actually filing patents on genes that are thought to cause certain cancers. Is this providing incentive for medical research, or a frightening step forward in corporate control? David Koepsell, author of Who Owns You: The Corporate Gold Rush to Patent Your Genes, and Gene Quinn, patent attorney and founder of IPWatchdog.com, debate. This weekend saw the biggest protests in history, coordinated around the world, on the issue of global warming. Rev. Lennox Yearwood, President of the Hip Hop Caucus and co-author with 350's Bill McKibben of the article "People, Let's Get Our Carbon Down" in The Nation, joins us to talk about Saturday's actions, the hip-hop generation's involvement in environmental activism, and his new initiative, Green the Block, with Van Jones and Majora Carter's Green for All. The 350 protests weren't the only actions that took place this weekend. Activists kicked off the Showdown in Chicago by crashing the American Bankers Association party, and the public option was kept alive in part by some guerrilla musical theater at an AHIP event.
