Phizzy are you neglecting to realize how prophets of doom effect large numbers of people? Sometimes for bad, but more often for good.
Don't you think? I personally use lots less water, paper and plastic because I LISTEN to warnings. I drive less because I listened. Doom sayers are doing the world a favor by their warnings, but what do they get when people listen? Shit. And you think they don't know it? They sound the warning despite the inevitable conclusion that people will listen and halt the catastrophe and then they will look wrong. But not to wise people. They don't look wrong to wise people.
