Humans have been selfish in their relation with nature and aggressive towards the nature properties. To get benefits to themselves alone and to fulfill their many interests, Humans exploit the surrounding natural blessings and deprive the Earth of its healthy existence and heavenly divine look. They have been the cause of different gigantic problems to the planet‟s ecosystems which, in return, have caused uncontrollable physical and psychological catastrophes. They for instance pollute air, water and soil, clear away forests, acidify rains, expand deserts, kill animals and plants, and change the climate. Humans become victims of what they have done towards environment. This study is an attempt to show the psychological effects resulting from the human-inflicted environmental traumas as reflected in Jonathan Holms‟ (1975- ) play Katrina (2010). Katrina presents a detailed image of the sufferings of different sections of people, from different destructive ecological occurrences, to show how man pays the high costs of his anti-natural thoughtless transgression.
