Thank you Syed Aamir Shah, as a practitioner i can tell you that when i visit a field i see several insects flying here and there, at the same time you find some bugs that are in the soil - this is part of ecosystem where beneficial insects can fight against pests coming on the plant - this is given only in natural and organic fields. With inorganic, synthetic or chemical pesticides we kill any insect or microorganisms on the field, beneficial ones and pests. You will not notice any insect around you, it will be very very quiet place, but a very catastrophic situation for the soil, because the soil depends on its living creatures...
