(IGY) of 1957-1958, the International Biological Program was an attempt to apply the methods of big science to ecosystem ecology and pressing environmental issues. The IBP was organized under the leadership of C. H. Waddington beginning in 1962 and officially started in 1964, with the goal of exploring "The Biological Basis of Productivity and Human Welfare". In its early years, Canadian and European ecologists were the main participants; by 1968, the United States also became heavily involved. However, unlike other more successful applications of the big science model of scientific research, the IBP lacked a clear, socially and scientifically pressing goal. Many biologists, particularly molecular biologists and evolutionary ecologists, were sharply critical of the IBP, which they viewed as throwing money at ill-defined or relatively unimportant problems and reducing the freedom of scientists to choose their own research projects. The main results of the IBP were five

Though the impact of these studies was modest, the IBP marked a dramatic increase in the scale of funding for ecosystem ecology, which remained high (relative to earlier levels) even after the conclusion of the program in June 1974.
