Such outstanding protruding ears are due to the habitat of these animals - they use their ears as fans, fanning themselves to escape the heat. Elephants' ears have a completely unique network of veins, similar to human fingerprints. Developed blood supply to the ears helps animals survive the exhausting heat more easily.

It would seem that the formulation of the question is completely banal and simple - of course it is necessary! Almost everyone always does this all their lives. This is considered generally accepted hygiene rules. However, in fact, nature cannot invent a mechanism for the occurrence of earwax, and it has a useful practical meaning.
Earwax is a naturally occurring substance produced in the ears of many mammals, including humans. There is an opinion that sulfur is a sign of uncleanliness, but in fact it helps keep the ears clean, filters dust, debris and other substances such as shampoo. Thus, sulfur protects the ear canal from infection.
The ear canal in our body is essentially a “dead end”. Dead skin cells cannot be removed from it through physical erosion the way they can be removed from other areas of the body. Sulfur - creative solution this problem. 
Scientists say earwax carries important information about human health and nature. It traps dust, bacteria and small objects, preventing them from entering the ear. Sulfur also perfectly protects against water entering the ear canal.
Many doctors do not recommend removing earwax. Earwax plays important role in the functioning of the ears and, in most cases, there is no need to get rid of it. Our ears are self-cleaning, and if they are functioning properly, no intervention is required to keep them clean. In some people, the self-cleaning mechanism of the ears is disrupted, and wax becomes “trapped” in some part of the ear canal. This can happen for a number of reasons, including the anatomy of the ear (some people have very sharp curves in their ear canal). Or it may be due to insertion into the ear canal foreign bodies, such as cotton swabs, which can cause wax to actually be pushed further into the ear canal. 
Since the ear produces wax all the time, where the wax particles are pushed with a stick, over time a wax plug appears, which can remain in the ear for decades. Excess wax in the ear has a lot of side effects, including pain, general irritation and sometimes infection of the ear canal.
In some cases, ringing in the ears, buzzing, or other extraneous sounds occurs. The wax plug can touch the eardrum, or completely block the external auditory canal, which will impede the passage of sound. It occurs in 35% of people over age 65 and can cause mild hearing loss that resolves once the wax is removed. That is, our efforts to cleanse our ears actually disrupt their self-cleaning cycle. A few drops of water or natural oil(for example, olive or almond) can be very effective in softening the wax plug in the ear and facilitating its “migration” from the ear. If there is no improvement, then you should consult a doctor who may prescribe douching with water. The main thing you should never do is push anything into your ears in order to clean them.
