One thing I keep noticing in my travels in Thailand is the way Thais deal with garbage.
They usually simply throw it on the ground.
While in most larger cities, this is not a problem (there seems to be an almost invisible army of people cleaning up the streets so they are not overrun with garbage), in small towns and remote locations, this attitude towards garbage can be problematic.
I really do not know what the attitude stems from (my best guess is it has to due with a lack of garbage collection infrastructure, and the very rapid influx of manufactured goods that do not biodegrade)
It is however something that most Thais do not seem to notice, but something which I am not accustomed to.
I always feel terrible when I arrive at a presumably pristine location only to find it overrun with garbage.
