If I took every thing out of your house made of peritoneum completely or partially you would not have much. No electronics, the isolation on the wire is made of oil.(vinyl), your pluming,(PVC)or some other plastic in most newer homes. Containers made of plastic. The paint on your walls. Your roofing, your carpet, the cloth on your furniture, most of your clothing especially coats, your mattress,(if you have a good one) and most importantly, the food in your pantry,(fertilizer like ammonia to make nitrogen compounds). Want to live with out oil? Think 1870 technology, hard, but it has been done.
