Ok lets introduce more wolves and lions no problem the population grows the wolves make a new packs the lions have a new home range and yes they control the deer and elk herds but then with todays hunting population we have less numbers of game animals to hunt. Now we have a problem alot of people less game to hunt and yes some areas will close and people will be congested in one area ok now we can`nt control the preditors because there a protected spiecies. Lets see whos foot steps in the door first ya right the antis and they take are rights away to hunt because there is not a viable species to hunt so then it gets protcted and put on an endangered list. You really have to way the PROS AND (CONS)to see the long term afect.
Just my opinion.
