Hemp is the same species as marijuana, its scientific name is “cannabis sativa.” Both the U.N. and North American Free Trade Agreement recognize industrial hemp as distinct from marijuanna due to hemps next to nothing THC content. For thousands of years hemp was used to make dozens of commercial products like paper, rope, canvas, and textiles. In fact, the very word “canvas” is derived from a variety of european words that mean cannabis.
Many years ago hemp and marijuana were unjustly banned together; however, they have recently been rediscovered as a species that bestows upon humans, plants, and animals, myriad benefits in the form of great environmental, economic, and commercial potential!! The US Department of Agriculture once published a report which found that one acre of hemp can produce 4 times more pulp for paper than one acre of trees! In todays economy it is truly unknown what potential could lie ahead as modern technology, practices, and the production of new varieties of industrial hemp could all positively affect this potential as well! Hemp can invigorate our planet in so many untold ways!
In fact, all types of paper products can be produced from hemp: newsprint, computer paper, stationary, cardboard, envelopes, toilet paper, even tampons. FACT: IT IS UNLIKELY THAT ANY TREE OR PLANT SPECIES ON EARTH WILL EVER BE CAPABLE OF PRODUCING AS MUCH PULP FOR PAPER PER ACRE AS HEMP! HEMP IS & WILL REMAIN NUMBER ONE! Paper production from hemp would eliminate the need to chop down BILLIONS of trees! MILLIONS of acres of forests and huge areas of wildlife habitat could be preserved!! Associates of the tree farming industry claim that more trees are planted each year than are cut down. However, I do not know how long that could last. I'm guessing they do not have infinite resources to buy up larger tracts of land for tree farming. It seems like eventually supply and demand would even out and the industry would plant only the amount of trees that it needs for a sustained supply of fiber. Further tree planting efforts would be attributable to individuals, environmental groups & governments.
Hemp can be grown on most farmland throughout the U.S., but forests require large tracts of land available in few locations. MORE LAND COULD POTENTIALLY BE INCORPORATED INTO THE NATIONAL FOREST SYSTEM!! or used to enrich human life as well. Substituting hemp for trees would save forests and wildlife habitats especially because some trees live to be so old that farming them for their full lifespan is impractical. Allowing trees to achieve their full life span and beyond can be important because there are many organisms that have a relationship only with mature, old, or even dead trees. Additionally, the boots, treads, and logs of all the people & equipment doing the tree farming or forestry also thoroughly trample many little organisms that live on the ground. Trees are also a major player in carbon sequestration and contribute to the water cycle by returning water vapor to the atmosphere.
