Mike Williams assesses a key environmental ruling in the United States and investigates a supposed link between global warming and obseity. Plus, he finds time to watch a turtle race.
Last week, the Environmental Protection Agency in the United States took a major step towards declaring Carbon Dioxide harmful to human health. The ruling is likely to lead to more regulation of greenhouse gases and will put pressure on Congress to pass climate change regulation. Mike talks to Richard Lazarus, an expert on environmental law.

This week, Earth Day events have been held around the world. Mike talks to Dennis Hayes, who set up the first Earth Day way back in 1970, to find out how environmental campaigning has changed.
