We cut down forests, plowed flood meadows, and in their place we took up intensive farming. so bees lost their rich flower meadows, hedges, flowering trees and other habitats such as ponds and floodplains.
Many plants today begin to bloom earlier, when the bees are not yet ready to pollinate and collect nectar for themselves. and later, the bees do not have enough food, because the period of flowering of the main melliferous plants is over.
Pesticides are designed to kill unwanted pests, but their toxic properties and widespread use are also harming beneficial insects such as bees.
Industrial methods of beekeeping, such as migrating to monoculture fields, collecting all honey and feeding sugar syrup, and others, lead to weakening of the bees to fight pests and reduce the bees' immunity to diseases.
