Is Earwax necessary

Answer 1

Ear wax has nothing to do with germs.

The eustachian tubes (one on each side) help drain the sinuses and ears. Ear wax is a natural "lubricant" of the ear canal, much like saliva lubricates the mucous membranes of the mouth.

Ear wax darkens with illnesses or environmental changes. For example, cigarette smokers often produce more and darker ear wax than non-smokers.

It is true that ear wax "catches" insects, but only because of the sticky nature of ear wax. It prevents the insect from moving, but that also means the insect can't move OUT. Once trapped, the wax suffocates the insect.
