Legal Industrial Hemp Farming would be near death to many of the world's Multinationals, unless they were 100% in charge of it's production. It's a near limitless commodity that was made illegal by Big Oil, Big Plastic, Big Pharma, Big Timber, Big Construction... It goes on and on.
Prior to WWII, farmers were encouraged to plant Hemp for the war effort. Then, made illegal.
It's a magic plant.
