Pollinators are a diverse group of organisms that perform a vital role in the ecosystem. A pollinator is described as any organism that take pollen from one flower and directly deposit it on another flower.
Some different species of pollinators include:
Honey bees, bumble bees, etc.
Unfortunately, due to human influence (pesticides, habitat loss, reduction of resources, etc.), we are losing millions of pollinators. Without pollinators, our crops will go un-pollinating making it become a huge threat for the ecosystem and food security.
It is therefore our duty to protect pollinators by increasing available habitat, increase food sources and floral resources while also reducing the use of pesticides.
