I tried to describe the theme of moral ecology as the matter of relationship of man and his environment. There was an effort also to mention important connections and circumstances such as history of relationship of man and nature and connected human interventions there that have led to common state.. It is reflected as ecological crisis by big part of experts as well as public. This was by informations coming from reports about state of the world from seventies (when the crisis was recognized) and later from nineties and common time Then there were mentioned supposed causes of this situation. There followed brief exposition of authors dealing with moral ecology and their ideas. Afterwards the attention was focused especialy on strategies of voluntary or intentional simplicity and ways of reasonable consumption as the main practical displays of moral ecology as well as means to solve environmental crisis. The article on efectivity in production as the way of reasonable consumption was added. In the end there was placed part dealing with needed and possible ways of solution of ecological problems on the social, economical and political level. as the next important displays of moral ecology.
