One of the benefits of organic farming is the extremely minimal use of harmful pesticides. Despite the Center for Global Food Issues director of research Alex Avery’s statement that, “organic farmers are allowed to use a number of toxic chemical pesticides,” it has been proven by the ESRC Global Environment Program that there is less air and water pollution found on organic farms. The major ideal of organic farming is prevention rather than cure, meaning that organic farmers attempt to prevent problems before resorting to chemicals for a cure. Most organic farmers use beneficial insects and birds, mating disruption or traps to control pests and disease, while non-organic farmers use insecticides. However, in some cases organic farmers must turn to pesticides. Before executing use of any chemical, organic farmers must first be evaluated by the International Federation of Organic Agriculture Movements on several aspects including necessity, nature and way of production, impact on the environment, human health, ethics and animal welfare, and socio-economic aspects.
