Biography
As Forester was only a chemical engineer and not a biologist, he neither understood nor cared about the disastrous effects DN6 would have on the Earth's environment, as it would destroy insects vital to agriculture as well as those harmful to it; and considered Arnold Farrow's refusal to grant approval for the manufacture of DN6 in the United Kingdom in June 1969 to be a petty bureaucratic roadblock.

Forester murdered Farrow, then doctored his report to approve the insecticide's production. His crimes were exposed and he was arrested by PC Bert Rowse. (TV: Planet of Giants)
