Here are a couple links if you want to read some about it yourself.
The whole ordeal boils down to: down buy Grand Theft Auto for your child because it is bad for their development and can cause increases in angry and violent thoughts....
Now the Aspects of Grand Theft Auto:
-You go around shooting people
-You steal from anywhere or anyone
-You get chased by the cops and you try not to get killed
-You can indulge in different "foul" play throughout the game while they give you nonsense objectives on harming others or destroying things (usually).
Now, the hype of not buying this for your children seems to be completely based upon this: the children may harm other people (or things created by people) like they are allowed to do inside the video game.
So, humans in present day society are concerning themselves over other humans hurting them and other aspects of human life that animals can simply not grasp (according to the hype over this game and the research done behind it).
As the years have gone by, I can almost say that people in America, specifically, seem to be spending increasingly more of their time doing their jobs and worrying about aspects of human life (being in a car crash or being kidnapped and how to get to the next level on a video game or obtaining a high GPA).
Is OUR strive for knowledge (which is increasing inevitably) causing us to not concern ourselves with other species on this planet? (aside from pets obviously). Is this what is leading us to continually ignore animal's needs as it relates to their longevity?
EX: We are destroying the planet we live in order to "advance" as quickly as possible.
EX: We are destroying our planet, currently, because we need to drive to work (to work on things usually not related to animals at all and only for people).
EX: We create advancements in technology to slaughter our cattle more efficiently while the resources for cattle and new technology is scarce, precious, and valuable.
I find this an interesting insight into why animals in our society seem to be "suffering" and humans are continually fine with this. (To understand what i mean by suffering... if you show anyone a video of the inside of a cattle factory, they will be disgusted... and they will feel bad for the cow... that's what I mean).
