This book is about an experimental study carried out by the author to find out the effect of ecological intelligence on developing ecological sensitivity among prospective teachers. The experiment is conducted to enhance the prospective teachers’ ecological intelligence in order to develop their ecological sensitivity which is expected to be imbibed in student community for ensuring a safe environment to all living beings. The author has adopted Daniel Goleman’s idea of ecological intelligence and developed the concept of ecological sensitivity from the perspective of the mental disposition of an individual to deal effectively the dynamic environment with empathy by taking initiatives to mitigate the environmental problems for sustainable development since the prevailing environmental condition demands the human beings to quickly respond to the environmental problems in order to protect the environment not only for the continued survival of the present generation, but also to ensure safe environment for the future generations.
