Well sadly the only way to fix that is to go into several African nations and several others on the Asian subcontinent, forcefully relocate their populations elsewhere at gunpoint and then establish massive reserves that are constantly patrolled by drones, hi tech attack helicopters and other armed resources all with orders to shoot and kill poachers on sight, no questions asked. Sad thing is, you'd still be carrying out airstrikes against poachers on a daily basis. Might boggle your mind, that people would literally risk life and limb to poach - but if you'd ever lived in Africa you'd understand.
As for myself, sure, I'd love to see these critters out and about with thousands and thousand of acres to roam in - but I don't bury my head in the sand and pretend that things are different than they are, I understand that without zoo's many of these critters would probably go extinct, and if not for the conservation efforts made by most major zoo's to protect animals in the wild some of them would probably be there already.
So really if you honestly want to make a difference, then support your local zoo any way you can - buy a membership, take pictures and post them and hopefully encourage others to do the same. Frankly it's a lot more productive than complaining about what category they were posted in on some internet forum.
