Purdey's quest to discover the truth was hampered at every turn by government bureaucracies and self-serving scientific cliques who sought to smear and marginalize him. Dogged by dirty tricks and forced to work alone as something of a scientific sleuth, he struggled to reveal hidden interests and dangerous secrets. His supporters included many members of the public, as well as Prince Charles, as well as the poet Ted Hughes, who wrote to him expressing "a million congratulations."
Increasingly sceptical of the official narrative, Purdey was certain that toxic environmental factors would provide answers, and so embarked on a self-funded worldwide odyssey to investigate. Animal Pharm follows him on these eco-detective trails to locations as diverse as Iceland, Sardinia, Colorado, and Australia. Purdey uncovers contamination from industry, munitions, pesticides, nuclear experiments, and natural geology, linking these with the emergence of a range of neurodegenerative diseases. His research is at once compelling and disturbing, helping to create a paradigm shift in our understanding of the relationship of pollutants to disease and health.
