I spent a lot of time a few years back reading some Russian world traveller's photo blog (he looooved taking photos of signs and fire hydrants and such, which I wasn't super into but was sometimes interesting, but also posted plenty of other things—I misplaced the URL long ago or I'd link it) and the rule for off-the-beaten-path tropical paradises seemed to be that they were incredibly poor and absolutely covered in litter and improvised garbage dumps. If there were touristy sections it'd be every square meter of the place off the tourists' beach that looked like this.
