It is BS to throw ur garbage to another country.

Also BS: "Deflation poses a threat to economies because falling prices encourage people to put off spending in anticipation of further declines. Retailers then cut prices, profits fall and salaries are reduced, which can quickly lead to a deflationary spiral."
