They don't have to work to diminish it... We do it to ourselves every day. Look at the average age of those buying hunting permits and stamps, it goes up.... Like its about 42 yrs old right now...
Every year we lose more and more cause our kids do less and less. Yes, there are some parents out there gettin their kids outdoors and all but the effort is lost due to a lack in popularity.
More work needs to be done to get kids outside, it needs to be driven towards kids too... Less trophy crap and more outdoors stuff... More fun= more kids = more hunters for the future... as it stands right now, we are looking at being out numbered severly in the quite near future.
