Why can't scientists devote their time to positive research or experimentation ? Work on a 100 mph automobile, invent insulation or new materials to keep our homes warm in winter, cool in summer. Stop this bull-hockey of scaring us to death ! There are too many pseudo-scientists who have not a clue how to improve, improvise, or invent. We have too many medicine men,alchemists, and witch doctors, not scientists (most probably working for some government agency).
