I said nothing about selfish.  The right to produce food for the hungry is not selfish.  If so, the organic crowd is even more selfish because the food they supply costs more and deprives folks of needed assets.  There is no proven benefit of organic food.  You mention invasive spraying but do not define it.  I suspect that you would suggest that if any chemical substance can be detected with the best analytical methods, it is invasive.  Sorry, there is just reasonable basis for such belief.  In any event, there is no point in discussing this it is religion.
