Without sounding like popular '80s comedian Yakov Smirnoff, I'm an immigrant to this country and there are a lot of idiosyncrasies that stand out, still, even after 20+ years of living here, as super weird.
For instance: any supermarket is (literally and figuratively) full of plastic-wrapped items. You open the plastic once. You throw it away and it sits in a landfill forever. You even bring home the plastic-wrapped items in plastic bags that take forever to biodegrade, or just sit in the ocean for decades. It makes zero sense, but that's the way that it's been done for years, and there's a powerful plastic lobby to ensure it stays that way.
But what if it we could stop using so much plastic?
