1. Destruction of farms and reliable food source.
2. Weak economic system.
3. Americans increasingly on mind-altering drugs.

The article really should be read. The author brings these factors together, and is convincing that as one affects the other, US and other western civilization could come tumbling down.

I’m not running anywhere, and I am ready for the zombie apocalypse.
