大便救地球是一部综合评分7.0的美国电影。讲述了This documentary provides an intriguing and humorous glimpse into our species' impact on the Earth by exploring how one of the most simple and obvious solutions to aid the environment may lie in what we often look down upon as waste. It just may be that the hero we all need, but don't deserve, shall be apparent when 'Sh*t Saves the World.'  整体来说还可以，有些情节让人眼前一亮，不过整体表现中规中矩。
