Bees are most likely dying because, Pollution, Pesticides, Temperatures rising aka Global Warming, And microscopic parasities
The way bees make honey is by going up to flowers and and collecting a sugary sticky substance called nectar. Bees have 2 stomachs 1 for storing and digesting food and the other one for storing honey. Once their stomach for storing honey if full they will bring it back to the have and pass it off to a worker bee the bee chews the wax for about a half a hour then passes it onto another bee. They keep repeating that process until it turns into honey. Then they put the honey into a cell then close it off with wax so the honey doesn't get dirty.
