The obsolescence is the process that most of the products follow. This process is that one product has a maximum time to be used, when it meets the time period can not be reused. This process is followed because the products that follow it are usually essential objects in our day to day.
An example of obsolescence is the light bulb, after 1200 hours the light is fused, and light is essential.
My opinion it`s that this create more money but more contamination.
