Anchor: Why are canned bottles so rich in Holland?

Because cans and bottles are mostly used for storage in Holland, they have money. Of course, some Dutch people use him to grow some green plants, most of which are hydroponic. In our country, canned bottles have no specific purpose. Most of them keep whole grain bottles, mostly beans, after eating canned food. In the north, we can have some pickles, or some pickles, which are easier to keep in the refrigerator. So rich.
