William Randolph Hearst (Citizen Kane) and the Hearst Paper Manufacturing Division of Kimberly Clark owned vast acreage of timberlands. The Hearst Company supplied most paper products. Patty Hearst's grandfather, a destroyer of nature for his own personal profit, stood to lose billions because of hemp.

In 1937, Dupont patented the processes to make plastics from oil and coal. Dupont's Annual Report urged stockholders to invest in its new petrochemical division. Synthetics such as plastics, cellophane, celluloid, methanol, nylon, rayon, Dacron, etc., could now be made from oil. Natural hemp industrialization would have ruined over 80% of Dupont's business.
