I love research about success stories of biocontrols for pests which negates using science-based Agro-Chemicals poisons. And yet, on the other hand, has anyone ever considered the money making economic potential for farming some pests ? This was really a fun read and reforces in myself how deceptive it is for any of us to judge various things in the natural world based on human concepts of good, bad, hate, evil, what is righteous, etc. Nature doesn't think and reason like us in those terms. You can almost count on if there is a problem, it developed because of human ignorance and land mismanagement. Ever wonder where many natural fabric or cosmetic dyes come from ?
