To fulfil self-need, human beings indiscriminately exploited ecological resources and thereby created serious ecological crisis and environmental degradation. Now, the situation has become so chronic and alarming that if sound measures are not taken, it may shortly arises the condition of extermination and devastation of human race. Fortunately, man has now, realized the vital role of ecological virginity and environmental purity for his healthy and happy existence. Hence, various conservative measures have been implemented and enacted to correct current ecological ravages. But it is to be regretted that after the enactment of hundreds of laws and introduction of environmental education and mass awareness programs; graveness of the problem has not yet been solved, though they demonstrated some degree of success. So the problem is still existing as a serious concern. In fact, success in the protection and conservation of ecology and environment lies at the root of attitudinal change and behavioural modification of a person. An individual must be free from greed, vanity, violence and thirst for self-satisfaction and over consumption.Until these deep rooted negative traits of personality are replaced by positive ones, mere enactment of laws will not be enough solution to ecological assault. Yogic lifestyle, through its ethical values under ‘Yamas’ and ‘Niyamas’ and psycho-physical practices refine the mental state, behaviour and attitudes of an individual. At this refined state of personality, individual start believing that all the creations are divine and life is meant for adoration not for violence and destruction. He also experiences that the whole nature is just like an essential part of his body without which he cannot survive. This unified state of consciousness paves the way for conservation of Ecology and Environment. As yogic lifestyle brings forth the feeling of ‘oneness’ or ‘ecological consciousness’, it can be suggested as a vary congenial model for conservation of ecology and environment.
