Hemp Essay I Found A Long Time Ago
What's So Great About Hemp?
By Lee Hitchcox
Historical tradition, if not current federal law, favors hemp. The U.S.Constitution, the Declaration of Independence, the Gutenberg Bible, and Old Glory (our nation's first flag) were all made from hemp as was the favorite fuel of Henry Ford, the reading lamp oil of Abraham Lincoln,the paints used by Van Gogh and Rembrandt, and the parachute webbing that saved the life of George Bush.  Hemp canvas covered the Westward-bound wagons, the tall sailing ships, the biplanes and zeppelins of World War I. Hemp was so crucial to colonial America that its cultivation was mandated by law. 
"Make the most of the Indian Hemp seed and sow it everywhere." ~George Washington, 1794

Hemp biomass can be converted into fuels (methane, methanol, gasoline) more efficiently than fossil fuels (coal, oil) and without the sulfur oracid rain.  Hemp fiberboard is stronger than wood; hemp houses are as strong as cement houses and better insulated.  Plastic, rayon, and cellophane made from hemp are biodegradable; plastic and nylon made from petrochemicals are non-biodegradable.
