प्रश्न
What care should be taken in order to reduce water pollution from non-point sources?
उत्तर
Non-point sources of pollution are the outside sources which affect a large area, e.g. run-off from agricultural fields and deforested areas. Run-off of manure should be diverted to the dry fields, there should be separate drainage for sewage to divert it with rainwater. Natural manure should be used and pest management system should be established for pest control to reduce the use of pesticides.
