Are there even really 90 billion bees in the whole of France??

90- billon dead over 10 years = 9 billion per year.
9 billion dead per year = 9 million hives with 1 thousand bees per hive, or 900, 000 hives with 10, 000 bees per.
so if the pop of FRance is 90 million people, and one in a thousand raises bees, that would be 90,000 hives at 100, 000 bees per hive
seems like an overstatement to me
