When I was young, my mother (who was a research chemist, no slouch in the intellect department) used to tell me that if you live long enough you'll see that most of what you read, see and hear in the news is BS. Even when they quote scientists, you should follow the money. The spectacular demise of the global warming scam with the release of the emails between "climate scientists" is proof of that.
I remember the alarmists with their "Zero Population Growth" nonsense. Periodically I still hear some "expert" talk about how our population is growing too fast and soon there will be nowhere for people to live. If you've ever driven around this country, you know that is BS. Only a person who has never left NYC or DC would think that.
