For example, Hemp can be used to make Hemp concrete aka Hempcrete which is 7X stronger than concrete, resistant to mold, self-insulatable and many more benefits , hemp can be used to make hemp paper and hemp plastic which is 10 times stronger than steel and much lighter, making it a great alternative building material for airplanes. The founder of Ford Motor Company, Henry Ford's first car was out of hemp plastic. In addition, hemp fibres can be used to make hemp fuel, cancer prevention medicine (hemp oil), textiles and clothing, nutritious protein source, and the list goes on... it's pretty much the most multi-functional plant the world has ever known, yet it is illegal, even though hemp can't get people high or intoxicated. Surely, science has not been the foundation for the implementation of this ridiculous law.
To extend this idea, hemp is a superior textile material to cotton from its production cost savings to the material itself.
Easier said than done, for the info image above, but definitely in the realm of possibility no doubt. Only if there is a movement from the people, we live in a democracy and if the science says this but the laws say otherwise. Is it not important to change the laws that align with scientific evidence? I certainly think it is.
