why do we need bees in the world
Where would we be without bees? As far as important species go, they are top of the list. They are critical pollinators: they pollinate 70 of the around 100 crop species that feed 90% of the world. Honey bees are responsible for $30 billion a year in crops.
That s only the start. We may lose all the plants that bees pollinate, all of the animals that eat those plants and so on up the food chain. Which means a world without bees could struggle to sustain the global human population of 7 billion.
Our supermarkets would have half the amount of fruit and vegetables. It gets worse. We are losing bees at an alarming rate. Possible reasons include the loss of flower meadows, the crab-like varroa mite that feasts on their blood, climate change, and use of pesticides.

Additionally, with the increase in global trade and transportation, blood-sucking parasites, viruses and other bee pathogens have been inadvertently transmitted to bees throughout the world.
These parasites and pathogens weaken bees' immune systems, making them even more susceptible to effects of poor nutrition from lack of flowers, particularly in countries with high agricultural intensity and pesticide use.
