It’s amazing to think there wasn’t any plastic one hundred years ago. Now it’s everywhere. Almost everything that’s made has some plastic in it. Whoever invented it must be really rich. There are all kinds of plastic. It’s pretty useful stuff. I once went to an exhibition on plastic. I was shocked to see just how important it is in our lives. Look around you and count how many things you see or have or are wearing that are made of plastic. One day, we’ll need to find a replacement 1 for plastic. That’s because oil will run out and plastic is made from oil. Maybe in the future there’ll be plastic museums full of valuable plastic. People will buy antique 2 plastic. I think I’ll save some pens and plastic carrier bags. They might be worth something in the future.
