From Britannica: "Living a “natural life” was the only option for people before the advent of plastics and other manmade compounds. Recently there has been a move towards using natural, unprocessed - or minimally processed - products for daily necessities that can certainly help reduce not only the environmental impact but also make a positive difference in the home and surroundings. Innovation and wise resource management have made natural forms of fiber, construction materials, and food preservatives more readily available."
