Are you worried about global warming? Should you be worried about global warming? Understanding the dangers posed by climate change and evaluating policies toward it require some understanding of science. How do we know the Earth is warming? What will happen when the temperature increases? What can be done to mitigate or avoid the problems? These are essentially scientific questions.
What about bird flu? MRSA? AIDS? Pandemic disease is something that can only be understood and combatted through science. Are we all going to get wiped out by some disease? What steps should we take to avoid being wiped out by disease? These are essentially scientific questions.
If you have no interest in science and being informed, then you can only blame yourself when you get conned by someone peddling antiscience, or swept up by FUD.
