the difference between natural and artificial is a symantic argument at best-oxygen is the most natural of substances right? its everywhere it occurs in almost every environment on this planet, its necessary for our survival, etc-but until green algae developed evolutionarilly there was no such thing as oxygen-only nitrogen and carbon dioxide-so what im saying is oxygen was made "artificially" by green plants, the same way beer is made "artificially" by humans-our conciousness is just a catalyst for advancing nature
and for people who say that anything "not made by man" is inherrantly better or safer than anything "made by man" i say this-if i go harvest the posion ivy that grows in my back yard, dry it, cure it, chop it up, roll it in a spliff, light one end, and stick the other end in your mouth, are you going to inhale?
