How would like like a building material that is stronger than cement and SIX TIMES lighter?
Better yet, one of its main ingredients in the waste product of a plant that literally grows like a weed.
Well, Big Brother says you can't have it because the plant - hemp - is "dangerous to society."
Here's the reality about cement:
1. The manufacture of traditional cement is incredibly energy intensive, so much so that many cement companies seek and receive legal variances to not only burn coal, but also medical waste and used automobile tires as fuel for their kilns.
2. After oil refineries and chemical plants, cement factories are the most polluting factories in the world, spewing tons of microparticles containing toxins like arsenic and mercury into the air.
