We don't want our children picking up your opala after you've gone.  Maybe you should include a plan for it's dismantling and disposal.  How about starting now,  with the relics that are already there?  Think atomic waste, radioactive and lethal....where is it buried now?  Sometimes, no matter how great the discoveries are, we do not take responsibility for the disposal of the dead.  Worse yet, we don't even know how?
