Not to be rude, but I think people who believe the world is falling apart simply haven't read enough history. Civilizations have always teetered on the precipice of self-destruction; while it's true that WMD on the scale of nuclear weaponry are a relatively new invention, the use of biological WMD goes back a very long way (from hurling the corpses of plague victims over siege walls to giving smallpox-infested blankets to Native Americans). And what was Greek fire but a weapon of mass destruction? Sure, it killed only a couple of hundred at a time--but when there were fewer people on the planet, a hundred was statistically significant.
The human impulse to conquest, imperialism and ultimate self-destruction is not new, and, relatively speaking, not any worse than it ever was.
Particularly when JWs talk about increases in crime--having spent 9 years in law enforcement--I must point out that, while the NUMBER of crimes increase, as a proportion of population, it's pretty constant. (In actuality, the per capita crime rate in the US has been on a downward trend since the '80s. Simple--or slightly simplistic--explanation: fewer young men. It's all about demographics. Males between the ages of 15-25, if not properly occupied with socially acceptable ways to release their aggressive impulses, will get into trouble.)
One of the things my JW mother goes off on is the increase in immorality and sex crimes--sexual abuse, etc., just "didn't happen like this before" (meaning before the "time of the end")--and all the horrific acts of violence detailed on the nightly news (think Jeffrey Dahmer) are, to her, recent developments. There's even a myth out there that Jack the Ripper was the first "serial killer," and that such murderous pathologies are a recent development. What's recent is: (a) the development of newspapers/other media outlets that can raise circulation/ratings by touting "mad killers" (it's only if you hear about it that it becomes a threat), and (b) the development of policing techniques that make it possible for law enforcement to see the patterns in crimes, particularly in crimes committed in more than one jurisdiction (we've gotten better at detecting criminals, which means we catch more of them, which makes it appear that there are more of them).
The truth is, these things have always happened. There is absolutely nothing new under the sun when it comes to human behavior. We just (a) lacked media determined to spread the tales far and wide, so that instead of "film at eleven," the stories were transformed into scary campfire tales and spread by word of mouth, and (b) we didn't talk about such things (i.e., inter-familial sexual abuse of children). One of the old-timers at the police department told me once that the rate of incest hadn't gone up at all--but in the 50s and 60s, the PD didn't release info about it to the press and didn't talk about it at all, out of respect for the victims (they used to use a red pen when booking an incest perpetrator so that everyone would know NOT to release the information). His explanation? "Before Oprah, we just didn't talk about private stuff like that. Didn't mean it wasn't happening."
If you don't think graphic murders and child abuse happened "in the olden days," just read Chaucer. Or for that matter, the Old Testament.
It's simple logic--there's more of us (people) living in close proximity to each other, so the numbers of crimes have gotten larger. In certain situations (i.e., when economically depressed urban areas are flooded with guns and drugs, usually for the profit of people who don't live there), the rate does actually rise, but that's not inconsistent with historical norms--check out the history of New York City, especially the period immediately before and during the Civil War. When substances that a large number of people want to use are banned, crime follows (see Prohibition and the rise of organized crime).
As for the nuclear threat--well, technology has advanced. We've found more and better ways to kill more and more people. It puts a lot of responsibility on us to behave better, doesn't it? But does it really matter if, in a planet with only a few hundred people, one of them kills another with a rock, or on a planet with a few billion people, one group kills another with a bomb? Dead is dead.
BTW, the pollution of the early industrial age was far worse than it is currently (though we could certainly do more to improve the environment, IMHO). In the mid-19th century, London's air was worse than L.A.'s in the mid-1960s. Mill girls in 19th-century Massachusetts routinely coughed up bits of cotton lint that they'd aspirated. And remember that the Chicago River was so polluted, it actually caught fire and burned. Cholera outbreaks from polluted water supplies were common in the developed western countries.
Things just aren't that bad--unless you watch Fox News!
