1 . Professional chemistry operations have enabled scientists to produce replacements for natural products: Discuss the problems associated with downsizing world assets with regard to 1 identified organic product that is not a precious fuel, figuring out the substitute materials used and/or current research set up to find a replacement for the named material: PLASTIC: Natural Rubber: Up until the 1940's, most rubber was sourced via plantations of rubber trees in exotic areas including Malaya and Burma. These types of trees can be ‘tapped', that may be, an incision made into the bark from the tree plus the latex systems applications and products collected and refined right into a useable rubber. Demand for natural rubber elevated greatly during WWII (mainly for armed service vehicles), and provide routes were interrupted by conflict. While the natural sources...
