According to the song "What the World Needs Now" which was written in 1965, the thing the world needs is "love, sweet love."
I disagree.
What the world needs now is a swift and virulent pandemic.
I believe that many of the troubles in the world are being caused by the gross overpopulation of the planet. In short, there are way too many freakin' people around.
Consider: As the population rises, more and more land is gobbled up for use in building houses, mini-malls, new roads, and Starbucks franchises. Land being used for these purposes is no longer available for crop planting or livestock raising, which means that less food is produced. So the number of people needing to be fed increases while the amount of arable land decreases. Anyone else see the problem here?
And obviously, more people means more consumption of disposable items, which increases the pollution problems that are also killing the planet and will, in turn, kill its inhabitants. Just not quickly enough.
People are not meant to breed like prey animals. Women should not be lauded and given a badge of honor for having litters of children. There's a reason rodents have lots of babies at one time - it's called predation. If a mouse has twenty mouselings, there's a good chance that perhaps a quarter of them will survive to create more mouselings. Aside from other humans, Mankind has no natural enemy. There are no dragons or dinosaurs around to prey on us, and modern medicine has improved to the point where most babies survive to adulthood. I could understand the reasoning in the old days of having twelve children - some of them would die young and you needed a flock of children to help run the farm because you didn't have machinery for plowing and harvesting. We're not living in "the old days" any longer. Stop with having so many damned kids. [I blame some of this on the Catholic church who says it's a sin to use birth control. Ummm, isn't your God powerful enough to make a pill or condom fail, if it's truly His will that you should be fruitful and multiply?]
Adding to the population overload is that fact that more and more people live longer these days. There are marvels of science and medicine to keep people from succumbing to the plague. So not only are scores of new people arriving, we're not losing people quickly enough to balance things out. There was a great definition of death on the old "Dave's World" TV show. Dave's young son wanted to know why people had to die, and Dave told him, "Life is like a merry-go-round. Some people have to get off so other people can get on." In today's world, people aren't exiting the merry-go-round at a fast pace, and there's no room for the newcomers.
I'm sure some people might think, "Oh sure, you're all for a global pandemic as long as it doesn't affect people YOU love." And if they think that, they'd be - pardon the pun - dead wrong. While it would be optimal if a plague only wiped out the morons and evildoers among us, I would still welcome it, even if it took people I care about, even myself. We are dying slowly right now, choking off our supplies of clean air and clean water. I'd much prefer a swift death to one brought about by starvation, suffocation, or dehydration.
Eventually, there will be a mass extinction. The Earth's history bears proof of several former extinctions, and there's no reason to think there won't be another, especially at the rate we're destroying the planet.
I say, bring it on. Leave the place to the non-human animals. I'm sure they'll treat their environment better than the homo sapiens have.
