Use of hemp cord in pottery identified at ancient village site dating back over 10,000 years, located in the area of modern day Taiwan. Finding hemp use and cultivation in this date range puts it as one of the first and oldest known human agriculture crops. As explained by Richard Hamilton in the 2009 Scientific American article on sustainable agriculture “Modern humans emerged some 250,000 years ago, yet agriculture is a fairly recent invention, only about 10,000 years old … Agriculture is not natural; it is a human invention. It is also the basis of modern civilization.” This point was also touched on by Carl Sagan in 1977 when he proposed the possibility that marijuana
