Points: Can stop the use of tree products that have contributed to deforestation Trees cut down to make paper take 50 to 500 years to grow‚ while hemp can be cultivated in as little as 100 days and can yield 4 times more paper over a 20 year period. Until 1883‚ from 75-90% of all paper in the world was made with cannabis hemp fiber including that for books‚ Bibles‚ maps‚ paper money‚ stocks and bonds‚ newspapers‚ etc. 2 Hemp paper is longer lasting
