In-different Observation # 2

need to check the facts as to why... but without any background knowledge or "research" into the field... i'd like to know WHY eatables marked "Bio", which are supposedly grown organically, without fertilizers, et al, are MORE Expensive than regular food in the market? i mean, if everything required to produce is freely available in nature (come on, there are many efficient ways to irrigate plants!), why do we need to pay more for the same damn thing?! ah, staying "healthy" is a costly affair...
