This week Jon Stewart is in Louisiana to present a special programme looking at the impact of the Gulf of Mexico oil spill, which occurred a year ago. Scientific research looks at the effects of the spill on crab and shrimp populations. We also reflect on the Chernobyl nuclear power plant fire twenty five years ago and ask what that disaster can tell us to help deal with the current nuclear crisis in Japan
