Pest .....in my view

                             Pest .....in RamAsre's  view

                                   None of the organism of this universe is a pest

They are innocent animals and are the unit of the ecosystem having their active  role to sustain ecosystem. If any organism behaves like a pest ,it behaves under the  provocative conditions created by the man.Lets not consider any organism as a pest without assessing  its loss to be occurred through Pest Risk Analysis  process.
A pest organism may not be a pest if the loss caused by it is below ETL.While considering an organism  as a pest we consider only economic loss,ignoring its indirect loss pertaining to our health,Environment, nature and ecosystem which is not correct.
