Ronald Bailey (pictured) has an arts degree in philsophy and economics and formerly worked as a journalist at the business magazine Forbes. He has cast doubt on ozone depletion, global warming, limits to growth, species extinction, the dangers of DDT use, biotechnology and stem cell research.
In 2006 Bailey wrote an article entitled 'Confessions of an Alleged ExxonMobil Whore' in which he explains that he had stopped being a climate change denier and "that the balance of the evidence pretty clearly indicates that humanity is contributing to global warming chiefly by means of loading up the atmosphere with extra carbon dioxide from burning fossil fuels". However he asserts that the ExxonMobil funding of the organisations he was affiliated with and was paid by (and his small holding of ExxonMobil shares) were not the reason he had been a denier.
His books include:
Liberation Biology: The Scientific And Moral Case For The Biotech Revolution (2005)
