So you’re saying if we just switch our diet to mosquitos we’ll all be fine?
It comes from a study where bats were trapped in a chamber filled with mosquitoes to see how many they could eat.
A comparable experiment would be putting a human in a cage filled with bread crumbs to see how many the human eats.
In our natural habitat, we eat slices of bread and other food. We don't waste the time and energy of consuming bread crumbs unless given no alternative.
Yes, bats can eat mosquitoes, but why bother when there are much larger, nutritious insects to catch with the same effort?
