That is a myth. We don't have to change our lifestyle or rather we do but it can actually mean to a much better one, cleaner, healthier and more abundant. Imagine if we replaced most of cotton with hemp, replaced paper with hemp so that those millions of acres of forests can be left alone, replaced wood with bamboo and hemp, replaced crude oil with hemp oil and all the while growing hemp sequesters CO2 and brings nutrients to the surface of the soil and also removes heavy metals from soil. You didn't know this did you? Yeah well, that's by design. But do look into it. Everything I say is absolutely true.
