My father, Michael Allaby, who has died aged 91, was an influential figure in the development of green philosophy. Co-author with Edward Goldsmith of the key ecological text A Blueprint for Survival in 1972, he later also collaborated with James Lovelock, with whom he had an enduring friendship.
Michael wrote an astonishing number of books on the environmental sciences – more than 100 in total. At the heart of his work was a firm belief that scientific objectivity is key to the survival of humanity.
