After catching up from 7,000 miles apart, BeiBei brings up the topic of methane gas, that adds to global warming, but is not generated by humans, but rather, cows. With billions of cows on the planet, the amount of gas they expend is a serious contributing factor to climate change. John shares a solution that has been developed by one of the world's most popular fast-food chains-Burger King-by adding lemon grass to cattle feed, greatly diminishing bovine flatulence. The conversation moves to how solutions are built into the problems we create as humans, and another episode of "Earth Matters with Bill Kurtis" is part of the program. In a serious shifting of gears, BeiBei asks for an encore performance of Air Supply-and John drops the needle on another million selling song "All Out of Love." Finally, don't miss the end of the show discussion on... dung.
