Firstly, leather is made from the skin of animals, which is a natural material that has evolved to be durable and resistant to wear and tear. This means that leather is inherently strong and able to withstand a lot of use and abuse.
Secondly, the tanning process that turns animal hides into leather also contributes to its longevity. Tanning involves treating the hides with chemicals or natural substances that prevent them from decomposing and make them resistant to water, heat, and other environmental factors that can cause deterioration. This makes leather much more durable than untreated animal skins, which would rot and decompose relatively quickly.
The exact lifespan of leather depends on a variety of factors, including the quality of the leather, how it is used and cared for, and the environment in which it is kept. High-quality leather that is well cared for and protected from extreme heat, cold, and moisture can last for decades or even centuries.
However, leather that is exposed to harsh conditions, such as extreme heat or cold, excessive moisture or dryness, or regular wear and tear, may start to deteriorate more quickly. For example, leather shoes that are worn every day and exposed to rain, snow, and other elements may only last a few years before they start to show signs of wear and tear.
In general, the key to extending the longevity of leather is proper care and maintenance. This includes regular cleaning and conditioning to keep the leather supple and prevent it from drying out
