The honeybee population began reducing since 2007. Beekeepers have observed that bees are leaving the hive, queens, larvae, and resources with no obvious cause. Large, modern honey beekeepers experienced dramatic losses. Colony collapse disorder (CCD) carried public regard for the significance of pollinators, the human effect on their well-being, and the results of their potential loss. Numerous variables, such as parasites, diseases, pesticides, limited floral resources, winter survival rates, fluctuations in the honey market, etc., add to bee colony loss. Apart from this, bee species are facing very serious environmental threats.                                                 

Honey bees aren't the main bees in danger. No less than 45% of Europe's honey bees are in population decline because of living space/habitat fragmentation and loss of foraging plants. In North America, four types of bees are in decline, and one is already extinct. We know considerably less about the preservation status of solitary species. Ongoing proof recommends that 49 eastern North American bee species are in decline, including ground nesters, stem and cavity nesters, brood parasites, and narrow host-plant specialists.

Pollinators are essentially linked to food security, but sadly, the bees and various pollinators, such as bats, butterflies, and hummingbirds, are increasingly under threat from human activities & several environmental factors. Changes in weather patterns, intensive farming practices, habitat loss, and the excessive use of agrochemicals pose a threat to plant varieties critical to human well-being and livelihoods.

Air pollution is also remembered to be affecting honey bees. Fundamental research shows that air pollutants interact with fragrance particles delivered by plants which honey bees need to find food. The mixed signals obstruct the honey bees' ability to forage productively, making them increasingly slow and compelling at pollination.

While most pollinator species are wild, including in excess of 20,000 types of honey bees, the mass reproducing and large-scale transport of pollinators can pose risks for the transmission of pathogens and parasites.

Taking Urgent Actions will be Helpful –

The European Association in 2017 partially banned the use of three insect sprays known as neonicotinoids to relieve the deadly danger they pose to honey bees and their trickle-down effect on pollination as a whole. Later at the United Nations Biodiversity Conference (COP15), it was decided to reduce the usage of pesticides by at least 2/3rd by 2030.

Expanding crop and regional farm diversity, as well as designated habitat conservation or restoration, is one approach to fighting environmental change and advancing biodiversity.

However, taking other actions like planting nectar-bearing flowers, raising awareness among the people on the importance of bees, setting up a pollinator farm, preserving old meadows, and using herbicides are helpful in preserving bees and other pollinators.
