I was deeply interested by the contrasts in this BBC news report, and the inexplicable, unpredictable response of humans. It seems there is a question to be asked: what explains or predicts human happiness? Can one be “happy” in a poisonous environment? Obviously, yes. I love clean air and pure water and think I can’t live without it, but perhaps we need exuberance, human laughter, shared community more than a perfect atmosphere?
