And people would harvest hops and then hang them in their house, typically kitchen where they would dry out and be used to make beverages, typically beer. If you mess around with beta alanine and manganese (chloride), be prepared for an increase in olfactory sensing (smelling), and you'll soon discover the rotting smell of vegetation when things get damp, foggy or it rains amongst many other things. I pity our canine friends. I think humans wouldnt live in such damp environments if they could smell how bad it is, but as they cant normally/couldnt in the past, would explain the migration to damp conditions in human history, instead of mastering irrigation in arid environments. So whilst the growing of vines and other vegetation on buildings could work at absorbing the ultraviolet and infrared radiation spectrum to reduce urban cooling, is it such a thought out idea, or are we increasing a new bacterial attack vector into our immediate environment?
