People who use the "look at the last (10, 20, 30 years))" stuff need to consider this. Technology is going to hit its peak soon, especially with hunting. I think the bigger problem will we be land and access. Poaching and trespassing are going to be on the rise because of this.
In the early 1900s, some proposed the closure of the U.S. Patent Office because "nothing else could be invented".
I do agree that land is going to be steadily decreasing if we dont stand up and do something to stop all of the developing and building.
