I read a book by the world's first zero-waste restaurant, Silo. The book got me thinking about how different our lives would be if oil were expensive. "Pretend oil is really expensive" is a good proxy for doing things that are "eco-friendly." Since reading the book, I've tried to eliminate single-use plastic from most of my life. It's incredibly hard. Everything from my socks to my vegetable packaging to my dog's toys to my floor is made of plastic.
I've slowly been adjusting my habits - such as checking whether clothing is natural or oil-based, buying food mostly at the farmers market, and eating in instead of takeaway. These little change have decreased my carbon footprint immensely.
I enjoy playing this game of "pretend oil is expensive" even though it's not because it's revealing problems we will need to tackle as a society. At some point we will run out of oil. When that happens, everything will be impacted. Travel, food delivery, and most of all healthcare.
