What would they gain from instilling fear in the masses?
Sure I could write up a huge essay like answer, but I can sum it up in a few words.
Suggestive minds.
(okay, I decided to make an essay like answer)
They give us fear, we look to them for answers. With the power in their hands, they feel more and more like a dictatorship. Once a certain gov't style progresses, it always finds a way to corruption. Democracy is no exception.
The problem doesn't stand in finding a way to beat global warming, as I've stated many times before, the fact that humans have developed intelligence that makes it possible to do what we're doing is evidence enough, that what is happening, is probably a natural step in evolution.
Come on, do you really think we can kill the earth? If anything, it will shuffle it's feet and kill us all. Or make an attempt at it (a test) to see if we can change our inner-most nature for the better. At which point, human's will have huge differences amongst intelligence levels etc. and it will be a fresh new world.
Intelligence is natural. Intelligence is natural.
Stop being a doomsayer, and feeding on fear, you apathetic excuse for a race.
Isn't it amazing, we've been blessed with all of these beautiful emotions, yet as a whole, the human race is still able to stand for complete apathy. (We really must not be as intelligent as we think)
