Honey bees are going extinct because of excessive use of pesticides in crops and certain blood-sucking parasites that only reproduce in bee colonies. It’s true that the extinction of bees would mean the end of humanity.
"For many of us, honeybees are annoying. We think that their only purpose is to keep buzzing around and dropping their formic acid-laden stings on random people (this impression will certainly change when we stop getting spoonfuls of sweet honey in our morning cereal).
The truth is, honeybees are crucial elements of our environment, and almost never get the credit that they deserve.
If bees didn’t exist, humans wouldn’t either.
Bee extinction – Why would it affect us?
Out of the 100 crop species that provide us with 90% of our food, 35% are pollinated by bees, birds and bats (source). It’s that simple.
Bees are the primary initiators of reproduction among plants, as they transfer pollen from the male stamens to the female pistils."
Since 2006, the population of bees has declined considerably (source). Pesticides, disease, parasites, and poor weather due to global warming have played a major role in this worrying decline."
