Lately, the numbers of newbie adventurers has seen a massive increase. There is a reason for this.
A useless goddess in charge of reincarnation has been sending weaklings and newbies to a world that has been labeled as "Ultimate difficulty ruined world" (our world) and to make things worse, she is sending them to Argentina.
These weaklings with no skills and zero common sense have been having trouble finding a decent job, and have been hunting low level rats and snakes in exchange for a few coins. These small rewards are barely enough to afford 2 rice bowls per day, which is actually causing a lot of problems for the local population, as the number of adventurers is huge, and local rice production is just not going to be enough to meet local demands in the near future. With no chance of extending the size of the wetlands used for rice production, and a huge influx of new adventurers, things might get ugly soon.
If these adventurers don't get a proper job soon, rice might become a scarce high-priced luxury.
