So what
So far we have littered the Moon, with plastic bags and bits of lander. Mars has had allsorts of stuff dumped on it, along with all the other junk in space in the name of science and now Musk thinks it is a good idea to put 100 meatbags in a giant rocket. I supposed on the plus side that is 100 less rich idiots around when they get incinerated on takeoff. landing or suffocated when something goes wrong a the far end.
