One day Homo Sapiens became so almighty that he no longer needed to think. He got more and more fat. So he had to throw away more and more pants. He then found no better thing to do than to start producing more and more pants. He produced a huge amount, just in case. In case he would run out of pants.
Trees will manage, so will the pants. Perhaps pants will even go through a renaissance. If Sapiens ever wants to be of any help, the only wise thing to do is to return to dust.
