Self-righteousness, also called sanctimoniousness, sententiousness and holier-than-thou attitudes is a feeling or display (usually smug) of moral superiority derived from a sense that one's beliefs, actions, or affiliations are of greater virtue than those of the average person. Self-righteous individuals are often intolerant of the opinions and behaviors of others.
The term "self-righteous" is often considered derogatory (see, for example, journalist and essayist James Fallows' description of self-righteousness in regard to Nobel Peace Prize winners).
No other species but humanity destroys its own kind for "ethical" reasons with the aid of technological "advances". No other species would be that righteous. No other species can pave over wetlands and then be amazed that rivers flood. No other species is that foolish. No other species can "harvest" 500 year old forests under the assumption that they can be replaced within 50 years. In fact the concept of "harvesting" the wilderness is a particularly repugnant terminology that pretends that all the earth is merely an outcropping of the agricultural revolution.
