> Why is mass tourism such a problem today and not the 90s/2000s
Back then was mostly Western tourists, and maybe a smattering of other folks. Now much of Asia has caught up, as has Eastern Europe and parts of MENA. Volume has just increased.
Cheapo flights like RyanAir + cheapo accommodations like AirBnB also make it feasible for less well off folks to travel. Again, just spiking the volume.
