2. Petrochemicals  Early 1800’s the only materials that were used were “found materials” - materials that occurred naturally (wood, stone etc)  Now, most of our products are created by materials that the people from 1800’s have never seen.  Early 1800’s the only materials that were used were “found materials” - materials that occurred naturally (wood, stone etc)  Now, most of our products are created by materials that the people from 1800’s have never seen.
