What's the big deal, Everest can handle an infinite amount of trash, just like our atmosphere. No worries, what could go wrong? Just keep piling it up...
The good news is they cut fees for the individual climber from $25K to $11K, which will entice more climbers with more trash each year. If they don't come back with 18 lbs of trash, so what, the penalty is less than the fee cut.
