In my oppinion you’ve made an really good article about this topic, although it’s very difficult to not offend the people because it’s still in their mind that cannabis (in every way) is bad for the humanity, although there are enough studies which prove the opposite.
Related to the use of hemp you’ve also mentioned nearly all the necessary points like for cosmetic, textiles, building materials and very important the medical effect which it has. There are a lot of more people where the „normal“ medicine doesn’t help (anymore) and with hemp they can be healed or the restrictions can be made bearable.
You’ve mentioned a lot of points why they should change the paper-production from wood to hemp, but as you said it’s still in the people brains that cannabis is dangerous and bad. Apart from that it’s also a money-factor, that the paper-industry does use wood instead of hemp. They can make more money with paper from wood than with paper made by hemp. But I think the planet should be first an business second and not the other way round because it’s our task to look forward that our next generation can live without any problems made by us.
