Which factor can negatively impact pollinator populations?

The use of non-selective herbicides can negatively impact pollinator populations because these chemicals kill a wide range of plants, including those that provide essential food sources for pollinators like bees and butterflies. When flowering plants are eliminated from an area, pollinators that depend on these plants for nectar and pollen find themselves with fewer resources. The decline in available food not only affects their survival but also their reproductive success, leading to decreased population numbers.

Conversely, increased flowering plants, the creation of wildlife habitats, and organic farming practices typically support and promote pollinator populations by providing diverse food sources and healthier ecosystems. In summary, while some practices enhance pollinator habitats and food availability, non-selective herbicides have a detrimental effect by indiscriminately removing vital plant species from the landscape.
