Bee populations in North America have been in a tailspin since the 1940s. This has made people in the agriculture industry, especially farmers, worried sick. Why? Because about 75 percent of specialty crops depend on the services of pollinators. And the most economically important pollinators are bees. In the United States, honey bees and native bees are the key bee species. They contribute approximately $15 billion in crop value. The USDA's National Institute of Food and Agriculture (NIFA) invests in many research studies on bees. These include investigating the reasons for the declining populations, promoting pollinator health, reducing honey bee colony losses, and restoring pollinator habitats.

Explanation:

Bees are essential for agriculture and for this reason, the decline in bee populations is so worrisome for farmers and for life on the planet as a whole. That's because 75% of crops need the work of pollinators to produce food. These pollinators are mostly insects, mainly bees that exist in greater abundance in plantations around the world. The decline in bee populations is not only an economic concern, but also a humanitarian one, as this can drastically reduce food availability due to lack of pollination.
