The campaign against sparrows was initiated by Mao Zedong, the President of China. Officially, the Four Pests campaign was one of the most significant actions in the Great Leap Forward from 1958 to 1962. The four pests designeated for elimination were rats, flies, mosquitoes, and sparrows. The activities did improve the harvest at first, but later on locusts swarmed the country and contributed to the famine. This documentary shows how the Great Sparrow campaign was executed.
