Yeah . For the time being . the human being is having better and better life as a whole in terms of material wealthy . But what about others , animals . plants ?? when we are talking about something like world is being better or not . should we have included every aspect of lives into the consideration ?
We are on a way no back ,no companion , and overconfident over advanced technoloy in developing our life / when we are getting more and more civilized , we 'd better find ways how human being co-existed with others in harmony
