Traditional practices must be given recognition
The Green Revolution in the 1960s saved a large part of the world's population from famine. However, it did have a side effect: many a farmer, caring little for the environment, made extensive use of mineral fertilisers. As a result, rice stalks became too thin to resist insects which multiplied rapidly, leading to an abuse of insecticides. Karl Gerner stresses in his review, Partencuris of Helvetas (August 2004), that the global decrease in male fertility rates is related to heavy use of insecticides.
