There is no classifing the garbage.

In Japan, people always classify the garbage into can burning and cannot burn. But at MFWI, we don't separate the garbage and only throw away to one place. I was surprised at American's how to throw away the garbage. It is strange. Why do Japanese separate the garbage, and why don't American separate? Japanese are more nervous than American. I learned in Japan, if you mix the cannot burn garbage into can burn garbage, it will not good for environment. Because, if you burn some unburnable garbage, it emits some pollution to environment. American aren't concernrd about garbage? This is mysterious and cultural observation.
