I do have to say this. I think the reason this stuff happens, is, well, we as humans have really become overpopulated.

Look at what happens if you stick 30 rats in a cage made for 10, they will start to kill each other off. I think this is whats happening now, we have far too many people, and good old mother nature is starting to push back. I don't know that there is a solution, or even a reason for it all happening, other than we just flat out have hit the tipping point.

 

Personally i think you are wrong, as the person who had the gun was not fighting over a resource such as clean water or food. This person may have just had mental issues and over reacted in a very bad manner, with a gun pointed at society to get revenge or reparation of his past or present life.

I say it doesn't have anything to do with over crowding because he is not fighting for food, water, land space, etc in this certain situation and placed him self at the school.

 

Think about cancer and disease. Not everyone are going to be perfect, typical human beings. Think of it as an upside down bell shape curve. Most of the population is somewhere in the standard deviation where there are others who lie on the outside, the very gifted ones and the very non gifted ones. Obviously the more people we have on the planet, the more side effects show up. Just something to consider.

And dementia/altzheimers might be nature telling us that living too long doesn't do ya any good since everything else in the body starts to wear down. Another side effect to health advances. In any case, just stating the obvious and something to consider. The United States will want to try and fix the issue, but others will always pop up.

Kind of like the chicken pox. When I was a kid everyone got them around kindergarten. Now that I'm older I know many receive shots, and then receive booster shots when they're older because of not having the antibody from having chicken pox. You're more susceptible to getting shingles that is more dangerous.
