All honey bees are effecting through their existence an enhancement of natural nourishment resources, mainly by pollination of wildflowers, herbs, many tree species and other plants. They contribute to a better ecological balance and produce inter alia honey, wax, propolis and gelee royal. There are many species, e.g.: Western honey bee (Apis mellifera), Eastern honey bee (Apis cerana), Philippine honey bee (Apis nigrocincta) and Koschevnikov's honey bee (Apis koschevnikovi). Bees are very vital. They are endangered by wrong treatment and environment pollution. Albert Einstein should have said: "If bees were to disappear from the globe, mankind would only have four years left to live." (https://morethanhoneyfilm.com/).
