Organic farming relies upon a healthy organic soil Perth with an extensive and diverse population of microorganisms. Very few of these microorganisms attack living plants, and plants have developed effective defence mechanisms against those. So plant pathogens only cause serious damage if they become too numerous. In a sterile soil a few potentially harmful microorganisms facing no competition multiply quickly and can destroy crops. In a healthy soil the interaction of many microorganisms maintain a balance which keeps potentially harmful ones in check.
Humans also have evolved in a world teeming with micro-organisms. They live inside our bodies, and on our skin. They are a natural part of the world around us and we too have evolved defence mechanisms to protect ourselves from the harmful few. Why then do we upset the balance by cleaning and trying to sterilise our homes with chemicals more appropriate to hospital cleaning than a house? Disinfectants and antibacterial wipes for every surface, antibacterial soaps and even washing detergents.
Our bodies’ natural defences are stimulated by pathogenic organisms or by particles of dead ones which are present everywhere, including household dust. Antibodies are produced which protect us against that organism, and often against others. Exposing children to a wide variety of microorganisms over a period of time is particularly important in the development of their immune systems. The alarming increase in the incidence of allergies and asthma in recent years has been linked to the increasing cleanliness of the household environment. Children who have siblings to bring infectious organisms home and those exposed to farmyard animals which carry a large range of microorganisms, have better developed immune systems and a far lower incidence of childhood asthma.
The aim of cleaning should not be to kill all microorganisms, but to reduce the number present to a level the immune system can deal with, and to prevent potentially harmful ones from multiplying and spreading. This is more important in some areas than others. In a food processing factory cleaning standards will vary; areas where the risk of contamination is high may need to be sterilized but less stringent measures will be required in others. So too the kitchen in a house requires more cleaning than a living area or bedroom. In a kitchen you need floors and surfaces that are quick and easy to clean, but in other areas carpets can provide a useful repository for a range of microorganisms and microbial residue which normal carpet cleaning won’t completely remove.
Even in the kitchen there is no need for the extensive use bactericides and antiseptics. Soap and water will remove most bacteria from hands and surfaces; and proper refrigeration and cooking of food will stop them multiplying. Organic farming has shown that to grow healthy and vigorous plants without chemicals you need a large thriving community of microorganisms. Perhaps we should consider applying at least some organic principles to the growing of humans. Check this website if you are looking for right nursery supply.
