Recently in Japan there has been a lot of talk about P.M. 2.5. At first, I was thrown for a loop to figure out what it actually meant. I mean from watching the news I could deduce what it meant, but knowing the meaning that the Japanese gave it....that can sometimes be entirely different.
Well in this case PM 2.5 basically means pollution from China combined with the yellow sand that blows in from the Gobi Desert every year. The combination of these two is what the Japanese mass media call "PM 2.5".
The "PM" in "PM 2.5" means particulate matter. The "2.5" means the size in micrometers.
My good buddy Mexican Samurai did a video talking about it on YouTube. Check it out!
