I'm old enough to rememeber when they told us that we would be living through a new ice age by the year 2000, and we would all die when the ozone layer disappeared. They said oceans would be dead, and global cooling would destroy the world. They told us Acid rain will destroy all the forests. Overpopulation will result in worldwide famine. They said we would deplete our natural resources, and run out of oil. They said the polar ice caps would melt. Manhattan should be underwater by now. People in cities will need gas masks. Nitrogen build up will make land unusable.

and let's not even start with the lies they told us about coffee, fat, salt, and eggs.

Seriously now. NONE of this shit was real. Not one word of it, ever.

How come it's a problem this time

And why is it that the only way to fix it is to submit unconditionally to a worldwide super-government? That part really puzzles me.
