Good question....the usual cop out is it will all be taken care of by Jehovah. But humans (survivors), are the body desposers so what about the obvious after effects that have to be dealt with. Just read an account about what would happen to the earth if all people disappeared. Within 2 days all sewage systems would overflow. Within 7 days the atomic reactors would explode and release their deadly contents as there would be no one to operate the cooling towers..So I wonder how many experts in those areas the Wt society has...no time to train them. As usual the difficult questions are never anwsered...we should not speculate...all is under control....Yep.
