Like I just replied a moment ago earlier in this thread.

Imagine where we’d be if not for Bernays, Anslinger and Hearst.

Imagine how good the soil, water, air, and minds would be, if we had still been growing hemp copiously.

Unlike many other plant defences to insects, cannabis/hemp has sticky trichomes to capture them, and the main nutritious part for us is another two layers deeper. Not to mention, we have other uses for the trichomes, like for (very benign, non-lethal, non-addicting) medicine (... "king of panacea" they called it). And the plant is so vigorous itself, it's often called "weed", out competing other weeds we have less use for.

Ironically, hemp's even a powerful bio-accumulator, and can be used to clean up polluted soils. And can leave the soil in a better condition. Can even be grown in the same location for 20 years without rotation before any depletion/imbalance to the soil occurs.

This along with all the other advantages... how it produces versatile super-strong fiber along with food and medicine. Not to mention oil (for lubricants, fuels, plastics, etc), and nowadays, there's even a very cost effective way to produce graphene from hemp, so we can create things like carbon nano-tubules and buckyballs to make solar panels out of, or leave it as graphene sheets and create capacitor bank batteries, and more.

And it cleans the air 7 times more than pine forests do. Ever been in a pine forest? That's some seriously clean air already.

And I forget how many times more paper it can produce than trees too. And paper that lasts longer (way, way, way longer), and requires orders of magnitude less chemical processing too. And it's stronger. Same with cotton, orders less chemical processing, less labour intensive, and produces a product that lasts way longer.

I could go on and on and on further yet. But suffice to say already even at that point, one can see why the competing industries banded together to eliminate the competition.

Either we restore cannabis and start growing it again profusely, sooner, in wisdom, or, we do so later, in desperation (... or not at all (~ too late, all dead)).
