What if it turned out that you were, indeed, being lied to about this entire issue?
What if those who depend upon grants to fund their research were not as honest as you might assume?
What if politics and not science were behind many of these issues to cause people to assume they were true?
I have no intention of arguing this issue with anyone. Neither do I argue about abortion, HIV, politics in general nor even flogiston!
I will suggest that a critical part of evidence procedure in evaluating such issues involves being careful about data mining and inadequate sampling.
Those who wish to save the earth (and pin big green good guy badges on their horse manure eco-cars) are welcome to do so.
I always assume the world will not end.
I will take the bet of any fool who wishes to assume otherwise!
You cannot "save the earth".
You might be able to save yourself, though.
To me it is all a matter of numbers.
I am Number One. Earth first.
We'll log the other planets later!
