A tv host, Niel Cavuto hosted both ABC's John Stossel and environmentalist Robert F. Kennedy Jr. to discuss Kennedy's charge, from the stage of Saturday's "Live Earth" concert in New Jersey, that the ABC anchor, as well as Rush Limbaugh and Sean Hannity, have been "lying" about global warming and are "toadies" for corporations. Stossel asserted that some of Kennedy's comments about the environment are "silly" and brought up a number of big scares that have been promoted in recent years, some by environmentalists, that have turned out not to materialize. Asked by Cavuto if ignoring the issue may make it worse, Stossel responded: "Well, it's possible. And it's possible that the killer bees were going to come up and sting us all to death, and that Y2K was going to crash all the planes, and that the pesticides that his organization [Natural Resources Defense Council] is so upset about were causing the cancer epidemic, and the frog testicles were shrinking, were going to make us all sterile. The scares from the environmental groups have just come one after the other. None has been true."
