This chapter describes how disease and pest control is sometimes enhanced by different elements in the natural world.

Pages 148-149. When it comes to Mao’s war on pests and how this might have contributed to worse famine, there are quite a few sources. For example see: Whelan, CJ. et. al., (2008). Ecosystem Services Provided by Birds, Annals of the New York Academy of Sciences 1134: 25—60. “Whelan remarks that “Although information is only anecdotal, apparently the ’war against the sparrows,’ part of a pest-control campaign launched in China during Mao Zedong’s Great Leap Forward, led to massive increases in pest insects and, thus, crop damage, ultimately contributing to a catastrophic famine from 1958—1962 in which 30 million Chinese died from starvation.” This source can be found on-line at: http://onlinelibrary.wiley.com/doi/10.1196/annals.1439.003/abstract
