Answer:

here is ur answer

The impact of pesticides consists of the effects of pesticides on non-target species. Pesticides are chemical preparations used to kill fungal or animal pests. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields.[1] Runoff can carry pesticides into aquatic environments while wind can carry them to other fields, grazing areas, human settlements and undeveloped areas, potentially affecting other species. Other problems emerge from poor production, transport and storage practices.[2] Over time, repeated application increases pest resistance, while its effects on other species can facilitate the pest's resurgence.[3]

Each pesticide or pesticide class comes with a specific set of environmental concerns. Such undesirable effects have led many pesticides to be banned, while regulations have limited and/or reduced the use of others. Over time,[when?] pesticides have generally become less persistent and more species-specific, reducing their environmental footprint.[citation needed] In addition the amounts of pesticides applied per hectare have declined,[when?] in some cases by 99%.[citation needed] The global spread of pesticide use, including the use of older/obsolete pesticides that have been banned in some jurisdictions, has increased overall.[4]
