if there are any questions that are about science and not sentence structure I may have your answer.  The ACDC page is paraphrased from each audio recording of Dr.  William Courtney  online.  He does not simplify this because it is for 7 billion people's future.  If I hadn't paraphrased www.rawhemp.tk would be out of reach for many more folk.  Any suggestions to change the way I paraphrased him will be disregarded.
