For example, after a recent World Health Organization report warned that the Fukushima nuclear disaster in Japan had only slightly increased local residents’ risk of developing certain kinds of cancers, the environmental organization Greenpeace, deeming the figures too low, denounced the report as “a political statement to protect the nuclear industry.” Similarly, Robert F. Kennedy, Jr., an American environmental activist, has accused the United States government and the drug industry of conspiring to obscure the link between childhood vaccines and autism – a link for which there is no scientific evidence.
