From Wikipedia, the free encyclopedia
Pollinator decline is based on observations made at the end of the twentieth century of the reduction in abundance of pollinators in many ecosystems worldwide. Pollinators participate in sexual reproduction of many plants, by ensuring cross-pollination, essential for some species, or a major factor in ensuring genetic diversity for others. Since plants are the primary food source for animals, the reduction of one of the primary pollination agents, or even their possible disappearance, has raised concern, and the conservation of pollinators has become part of biodiversity conservation efforts.
