Industrial hemp is not just a food source; it is a clean, renewable resource. Per hectare, industrial hemp yields 4 times that of the yield from trees, and double the yield of cotton. Trees take at least 5 years to grow for paper or pulp, compared to hemp growing within 120 days.
Industrial hemp can also be processed into clothing, concrete and building materials, energy, bio-fuel, plastic, stone, paper, cardboard, car panels, animal bedding and feed, and was used for thousands of years before it was demonised and banned in the 30s. Archaeologists have found hemp textile dated 10,000 years old.
In 1933, Henry Ford said, that why use up the forests which were centuries in the making and the mines which required ages to lay down if we can get the equivalent of forests and mineral products from the annual growth of the hemp fields.
Henry Ford built a car made of hemp plastic, which was stronger and lighter than steel and fueled the car with hemp bio-fuel grown on his own farm. But the investors of the Ford car company insisted him not to use hemp, but petroleum oil.
Our planet is in dire peril due to climate change and a long drought, and drought-resistant crops such as hemp must be considered. Cotton uses enormous amounts of water and chemicals, the land is raped of trees and the dwindling oil is sucked from the ground like there is an endless supply.
