Pesticides are chemicals used to kill pests and other “rival” organisms which may cause damage to crops in agriculture. In some instances the vast usage of pesticides may create negative effects on the environment and its units like living and non-living organisms. Green criminology counts such harmful activities upon the environment as crimes or harms though such activities can be legal or illegal in nature. The case of the endosulfan disaster that occurred in Kasargod, Kerala can be accounted to environmental harms which detrimentally affected the environment and its units, especially humans. The pesticide endosulfan was sprayed aerially for around 25 years in cashew plantations situated in Kasargod and caused severe diseases and extensive malformations among people living in the region. In this paper the endosulfan disaster of Kasargod is approached through the green criminological perspective of environmental harms.
